LET’S RESIN 1/2 Gallon Casting Epoxy Resin

LET’S RESIN’s 1:1 epoxy system is designed for crystal-clear results with a bubble-free formula. The 32 oz resin and 32 oz hardener blend yields a high-gloss, scratch-resistant surface that resists yellowing. Its anti-foaming additives reduce air bubbles, saving time on de-bubble steps. The cured resin remains water and heat resistant up to 160°F, making it suitable for jewelry, coasters, and decorative pieces that require a durable, glassy finish.
Key features include a simple 1:1 mix, beginner-friendly handling, and a focus on maintaining clarity over time. The kit’s crystal-clear appearance supports vibrant color casting and resin art, while its protective layer helps preserve color integrity with light exposure. Ideal for projects that benefit from a high-brightness, transparent appearance.
LET’S RESIN Polyurethane Resin, 60oz 2 Part Casting Resin

This two-part polyurethane resin cures quickly, forming a white, durable plastic in about 10 minutes with a 2-minute working time. It delivers a fast path to prototyping and casting, especially when time is critical. The polyurethane chemistry provides faster demold times and an opaque white finish, differing from crystal-clear epoxy. The kit’s low odor, low viscosity, and simple 1:1 mix make it suitable for casting into molds, making figurines, and quick functional prototypes without heavy equipment for degassing.
Applications span from model making to decorative props, with reliable performance in room-temperature environments. The formulation emphasizes minimal shrinkage and bubble reduction, enabling smoother surfaces and consistent results across batches. It’s a strong option for rapid manufacturing workflows and high-volume projects where speed matters.
SPRESIN Model-Pro 32 Oz

Model-Pro is a professional-grade polyurethane resin kit designed for both beginners and experts. It features a simple 1:1 mix ratio and a quick 15-minute cure time, enabling rapid production of models, figurines, and prototypes. The kit is compatible with standard room-temperature molds and avoids the need for complex degassing equipment, making it suitable for hobbyists who still require dependable, high-quality casts.
Users benefit from low viscosity and an odor-conscious profile, helping projects stay comfortable during production. The fast cure supports high-output environments and allows for multiple casting cycles in a single day. Its versatility makes it a practical choice for art studios and makerspaces that prioritize speed without sacrificing finish quality.
Teexpert Epoxy Resin Crystal Clear 64OZ

Teexpert offers a 64 oz two-part epoxy system with a 1:1 ratio and self-leveling properties. The resin is described as crystal clear and bubble-free when mixed properly, with stabilization additives to resist yellowing over time.

The epoxy chemistry pairs well with bar tops, crafts, and commercial displays where transparency and durability are critical. Its broad application range makes it a versatile choice for makers exploring both functional and decorative castings.
Buying Guide: Key Purchase Considerations for 2-Part Resins
- Resin type and cure time: Epoxy generally yields crystal-clear results with slower cure times, while polyurethane cures faster and can be opaque. Choose based on project timeline and desired finish.
- Mix ratio and working time: Most kits use 1:1 by volume. Verify total working time to ensure you can finish details without rushing or air entrapment.
- Clarity and yellowing resistance: Look for UV stabilizers and color retention additives if clarity over years matters for your piece.
- Bubble control: Bubble-free formulations save time; consider self-leveling or anti-foaming features for large surfaces.
- Odor and safety: Low-odor, non-toxic options are preferable for indoor spaces or beginners. Always follow safety directions and use ventilation.
- Heat resistance and durability: For items like coasters or table tops, higher heat and scratch resistance extend the life of the piece.
- Viscosity and pourability: Low-viscosity resins flow easily into molds; higher viscosity resins hold detail but may capture more bubbles.
- Volume and scalability: If you’re completing many pieces, consider larger kits to reduce restocking frequency and ensure consistent results.
- Compatibility with molds and substrates: Some resins cure best in silicone RTV molds; check compatibility with wood, metal, or resin blanks you plan to cast.
