E-1001/H-1001 is a two-component, solvent-free crystal clear epoxy resin for art casting, jewelry making, botanical embedding, and decorative object encapsulation. Formulated for applications where optical clarity, surface gloss, and dimensional stability of the finished cast piece are required together, the system delivers Shore D 80 hardness with low viscosity for clean mold filling and effective object embedding - with crystal-clear, high-gloss results, minimal bubble retention with vacuum de-airing, and the option to cure at room temperature or under heat. The process requirements specific to casting - pour depth management, thermal control across section thickness, vacuum de-airing for bubble-free optical results, and embedded element preparation - are the subject of this documentation. Available for OEM production evaluation; sample testing is recommended before production release.

 

Broad adhesion compatibility has been observed across multiple substrate types including metals, ceramics, stone, paper, leather, wood, bamboo, and electronics. However, substrate adhesion alone does not determine application suitability - the mechanical behavior of the substrate in service must also be matched to the coating hardness. The Application Fit Matrix below identifies which casting and coating applications are appropriate for this system.

Key Takeaways

• Shore D 80 - hard, rigid, crystal-clear finished pieces. The cured casting is rigid and dimensionally stable - appropriate for jewelry and display items handled daily, keychains carried in pockets, and gift pieces that must maintain their form and appearance over retail shelf life and service duration. Shore D 80 provides meaningful scratch resistance against the abrasion modes that decorative cast pieces encounter in use.
• Low viscosity (E-1001: 2,000–4,000 cps at 25°C) - clean mold filling and effective embedding. Lower viscosity allows the resin to flow around embedded elements - botanical pieces, decorative objects, pigments, glitters - without trapping air at inclusion boundaries. The same property supports clean mold penetration in detailed mold geometries without air pocket formation at sharp corners or recesses.
• Vacuum de-airing recommended for bubble-free results. Mechanical mixing introduces air into the resin. Drawing a vacuum on the mixed system before pouring removes entrapped air before it is locked into the cast piece. Recommended for applications where any bubble in the casting is a quality defect - jewelry, photo encapsulation, and high-clarity display objects.
• Pot life 60 minutes (60g, 25°C); mix ratio 3:1 by weight (E-1001 : H-1001). RT gel 8–24 hours; full mechanical properties at 7 days. Accelerated cure: 80°C × 2 hours. Weight measurement required for consistent cure; volume measurement is not interchangeable.

 

Art Casting and Decorative Embedding Applications

Figure 1. E-1001/H-1001 application range: art casting, jewelry making, botanical embedding, photo and memento encapsulation, display object casting, and rigid decorative surface coating. For composite laminating (fiberglass/carbon fiber) and keychain/name badge surface coating → E-126/H-100. For leather/wood/bamboo coating → Shore A flexible system.

 

Art Casting - Decorative Objects and Display Pieces

E-1001/H-1001 produces a crystal-clear, high-gloss cast piece with Shore D 80 hardness - the combination of optical clarity and surface rigidity appropriate for decorative objects intended for display or retail. Low viscosity allows the resin to flow cleanly into mold geometries, wet the mold surface without gap formation, and settle around embedded elements without displacement. The cured casting exits the mold with a smooth, glass-like surface that enhances the visual appearance of any embedded elements - pigment layers, metallic particles, or three-dimensional objects - through its optical transparency.

 

This system is intended for decorative and non-structural applications. Structural or load-bearing cast components require engineering-grade materials with independent structural qualification. For composite laminating applications - fiberglass, carbon fiber, Kevlar - E-126/H-100 is the appropriate system for those applications.

 

Jewelry and Wearable Craft Casting

A pendant that will be worn regularly accumulates handling wear - caught on fabric, contact with skin moisture, occasional drops onto hard surfaces. Shore D 80 hardness provides the surface durability appropriate for wearable decorative pieces that see regular use rather than shelf display only. The crystal-clear finish maintains optical depth in layered castings - pigment gradients, embedded metallic leaf, mica powders - without optical distortion or surface haze.

 

Broad substrate compatibility across metals, ceramics, stone, and most non-PP/PE plastics supports mixed-material jewelry assemblies - cast pieces with metal findings, stone inlays, or wire inclusions - without requiring a different system for each substrate component. Adhesion to specific metal findings, wire types, and any plating or coating on the inclusion should be verified before production use.

 

Botanical and Object Embedding

For dried flower, leaf, botanical, and decorative object embedding, the critical process requirements are optical clarity around the embedded element and the absence of bubble formation at the element boundary. Low viscosity allows the resin to flow completely around the embedded element on contact, with sufficient time within the 60-minute pot life to allow air released from the element surface to clear the resin before gel. Vacuum de-airing of the mixed resin before pouring removes the air introduced during mixing; for botanical embedding where trapped air between resin and element surface is a common defect, vacuum de-airing is strongly recommended.

 

Botanical elements should be fully dry before embedding - moisture content in the embedded element affects both adhesion and optical clarity. Photo and paper elements should be sealed before embedding to prevent resin absorption and discoloration. Compatibility of specific embedded elements with the cured resin should be verified on a sample piece before production use.

 

E-1001/H-1001 can also be applied as a clear surface coating on rigid decorative objects where Shore D 80 hardness and optical clarity are required. For fiberglass and carbon fiber composite laminating, keychain and name badge surface coating, and other coating workflows - E-126/H-100 documentation covers the application range, substrate compatibility, and process guidance specific to those workflows. Both products originate from the same base resin platform, but the documentation, process guidance, and application validation focus are different: E-1001/H-1001 is organized around casting and embedding workflows; E-126/H-100 is organized around coating and composite fabrication workflows.

 

Processing Notes for Casting

 

Figure 2. Recommended process for bubble-free casting with E-1001/H-1001: weigh 3:1 by weight → mix thoroughly → vacuum de-air before pouring → pour slowly into mold → cure at room temperature (7 days) or 80°C × 2 hours. Mix ratio must be by weight - volume measurement is not interchangeable.

 

Casting applications introduce process considerations that surface coating does not - primarily pour depth, thermal management, and bubble elimination. Two-component epoxy curing is exothermic: the chemical reaction releases heat. In thin-section coatings, this heat dissipates quickly into the substrate and surrounding air. In casting - where the resin is enclosed in a mold and thermally insulated by its own mass - heat accumulates within the pour volume. For thick-section castings, pouring in layers with partial cure between layers allows each layer's exotherm to dissipate before the next layer adds thermal load. The specific layer thickness depends on mold geometry, ambient temperature, and pour volume; process development on representative samples before production use is recommended.

 

Mold release should be applied to mold surfaces that will contact the cured casting. Silicone molds typically do not require release agent; rigid molds (acrylic, aluminum, polycarbonate) benefit from a thin release application to avoid adhesion between the cured casting and the mold. Mold compatibility and release behavior should be verified before production use.

 

 

 

Selection Notes

Use these notes to determine whether E-1001/H-1001 is appropriate for evaluation for your application.

Art casting, jewelry making, and decorative embedding - casting into molds, embedding botanical or decorative elements - E-1001/H-1001 may be evaluated. Shore D 80 hardness, low viscosity for clean mold filling and embedding, and optical clarity are the system's core characteristics for these applications.

 

Rigid decorative surface coating - display pieces, gift items, promotional objects on rigid substrates - E-1001/H-1001 may be evaluated. Substrate must be rigid and dimensionally stable in service.

 

Fiberglass or carbon fiber composite laminating, keychain and name badge surface coating - E-126/H-100 documentation is organized around coating and composite fabrication workflows and is the appropriate reference for those applications. → E-126 / H-100 Hard Clear Epoxy Coating Resin - Shore D 80 for Fiberglass, Keychains, and Rigid Decorative Surfaces.

 

Flexible substrates - leather goods, wood and bamboo crafts, mixed-material decorative objects with flexible components - a Shore A flexible clear epoxy should be evaluated. Shore D 80 hardness accumulates stress on substrates that flex or move with humidity, producing edge lift and micro-cracking over time. → E-1188TT / H-1188TT Anti-Yellowing Clear Epoxy - Shore A 75 for Leather, Wood, and Natural Material Coating.

 

Anti-yellowing performance required for light-colored substrates - E-1001/H-1001 is a standard clear epoxy system; anti-yellowing performance is not specified. For products where optical consistency over extended retail shelf life is required, a formulation with anti-yellowing specification should be evaluated.

 

Outdoor or extended UV exposure - an outdoor-rated polyurethane coating system should be evaluated. E-1001/H-1001 is formulated for indoor service conditions; UV resistance is not specified in TDS.

 

PP, PE, or silicone substrates or mold materials - adhesion to these substrate types is not supported. Silicone molds are commonly used with this system for their natural release properties; the resin does not bond to the mold surface in this configuration.

 

Frequently Asked Questions

Q: How deep can I pour E-1001/H-1001 in a single cast?

There is no single universal pour depth limit - the constraint is thermal management of the exothermic cure reaction, which depends on pour volume, mold geometry, and ambient temperature. In open, thin-section pours (under approximately 5–6mm) with adequate mold surface area for heat dissipation, single-layer curing at room temperature is standard. For deeper sections, pouring in multiple layers - with each layer allowed to reach partial gel before the next pour - distributes the exotherm across time and prevents heat accumulation in the core of the casting. The appropriate layer depth for a specific mold should be determined through process development on representative samples before production use.

Figure 3. For casting sections beyond approximately 5–6mm, the layer-pour approach manages exothermic heat accumulation: pour first layer, allow to reach tacky gel, pour next layer. Each layer's heat dissipates before the next adds thermal load. Attempting to pour full depth in a single pour risks heat accumulation, discoloration, or stress cracking in the casting core.

 

Q: Is vacuum de-airing required for art casting and jewelry applications?

Vacuum de-airing is not required, but it is strongly recommended for applications where bubble-free optical clarity is a quality requirement. Mechanical mixing introduces air into the resin regardless of mixing speed or technique. Drawing a vacuum on the mixed resin before pouring removes this air before it is locked into the casting during cure. For jewelry, photo encapsulation, and botanical embedding - where a visible bubble is a defect that renders the finished piece unsalable - vacuum de-airing is standard process practice. For applications where minor bubbles are acceptable or will be sanded and finished, it may be omitted.

 

Q: Can E-1001/H-1001 be used to embed dried flowers and botanical elements?

Yes, with process preparation on the embedded element. Dried flowers and botanical elements must be fully dry before embedding - residual moisture causes clouding, adhesion failure, and bubble formation at the resin-element interface. For fragile dried elements that may release fine particles into the resin, a thin seal coat of mixed resin applied to the element before the full pour can stabilize the surface. For elements with complex three-dimensional geometry, vacuum de-airing after the initial pour helps pull resin into internal cavities and displaces air trapped between resin and element surface. Compatibility of specific botanical elements - including any dyes, preservatives, or coatings applied to the element - with the cured resin should be verified on a sample piece before production use.

Can E-1001/H-1001 be cured at room temperature, and when is heat cure preferred?

Room-temperature cure is a full capability of the system. At ambient conditions, the casting gels in 8–24 hours and reaches rated Shore D 80 hardness and mechanical properties at 7 days. RT cure is appropriate for heat-sensitive embedded elements - dried botanicals, photos, paper elements, and certain plastics that may discolor or deform at elevated temperature - and for large castings where oven processing is impractical. Accelerated cure at 80°C reduces full cure to 2 hours, which is appropriate for rigid mold casting on non-heat-sensitive objects where production throughput requires shorter cycle time. The 60-minute pot life applies under both cure paths - application or pouring must be completed within this window regardless of cure temperature selected. Mix ratio is 3:1 by weight (E-1001 : H-1001) - weight measurement is required for consistent cure.

 

Q: What mold materials are compatible with E-1001/H-1001?

Silicone molds are the most commonly used mold material - the resin does not bond to silicone, so release occurs naturally without additional mold release agent. Rigid molds in acrylic, polycarbonate, aluminum, or steel are compatible with a mold release agent applied to the mold contact surface; without release, the cured casting will adhere to these surfaces. Polyethylene (PE) and polypropylene (PP) molds are also release-compatible due to their low surface energy, though edge detail transfer may be lower than with silicone. Mold geometry, surface finish, and release agent selection should be evaluated on sample castings before production use.

 

Q: Before Requesting a Sample

To make sample evaluation efficient, prepare three items before inquiry: (1) application type - casting (mold geometry and approximate pour depth or section thickness), embedding (element type, dimensions, and any surface treatment on the embedded element), or surface coating (substrate type and surface condition); (2) cure constraints - oven availability or RT-only, and whether any embedded element is heat-sensitive; (3) optical clarity requirement - whether bubble-free results are a hard quality requirement (determines whether vacuum de-airing equipment is needed in the process). Mix ratio is 3:1 by weight (E-1001 : H-1001) - weight measurement is required for consistent cure.

Existing production lines do not need to match the reference cure profile exactly before evaluation. Initial discussion is intended to determine whether the application type, cure schedule, and embedded element compatibility are consistent with the system's performance range.

For art casting, jewelry making, botanical embedding, photo encapsulation, and decorative object casting where Shore D 80 hardness and crystal-clear optical clarity are both required, share your application type, mold geometry or substrate description, embedded element if applicable, and cure equipment available. This helps determine whether E-1001/H-1001 is a direct fit or whether process compatibility - pour depth, vacuum de-airing, mold release - should be reviewed first.

Sample evaluation is recommended before production release.

Evaluation discussions may include mold compatibility review, pour depth recommendations, vacuum de-airing process guidance, and cure schedule options based on the provided application and embedded element conditions.

All values from TDS. Pot life, gel time, and cure conditions depend on ambient temperature, humidity, casting section thickness, and pour volume. RT gel time of 8–24 hours reflects performance at standard conditions - lower temperatures and higher humidity extend gel time. For thick-section castings, exothermic heat generation increases with pour volume; pouring in layers with partial cure between layers is recommended for sections beyond 5–6mm to manage thermal load. Casting reaches rated Shore D 80 hardness and mechanical performance at 7 days (RT) or 80°C × 2 hours. Mix ratio is 3:1 by weight - weight measurement required; volume measurement is not interchangeable. Vacuum degassing prior to pouring is recommended to minimize entrapped air. Verify mold compatibility, release behavior, and embedded element adhesion under your specific application conditions before production use.
