Product Details And Comparisons
LET’S RESIN EPOXY RESIN 1 Gallon High Viscosity Kit
Features: This resin kit has a high mixed viscosity of 14208cps, thick enough to stay put while still flowing smoothly over surfaces. Suitable for coating tables, furniture, countertops, bartops, or floors, delivering smooth and glossy finishes on concrete, fabric, wood, and more. The kit includes 64oz resin and 64oz hardener, plus mixing tools and gloves. It uses a 1:1 mixing ratio with a working time around 20 minutes at 70-80°F and cures within 24 hours. Ideal for beginners and experienced artists, though tumbler-specific mold is not included. Self-leveling, self-degassing, and UV resistant to reduce yellowing.
Best uses: table tops, river table components, countertops, and surfaces needing a durable, high-gloss shield. This kit is designed for larger projects where a thick, self-supporting pour is desired.
LET’S RESIN UV Resin 200g — High Viscosity
Features: This UV resin kit has a viscosity around 5000-6000 cps, providing high viscosity and slower flow. It is well-suited for curved surfaces, sphere molds, water drop effects, and 3D detailing. It cures to a hardness around 90D with minimal shrinkage and low odor, and it’s designed for bonding high-permeability materials like glass. It’s particularly popular for small jewelry pieces, doming, and coatings that require precise shape retention and a crystal-clear finish.
JDiction UV Resin Upgrade 300g — High Viscosity
Features: The JDiction 300g UV resin features high viscosity (approximately 3700-3800 cps) to slow flow, aiding in detailed doming and precision sealing on small crafts. It emphasizes crystal clarity, low odor, and safety, with strong anti-yellowing properties and a glossy finish. It’s designed for small projects like domed charms, mini sculptures, and jewelry components where sharp details and a smooth surface are essential.
HeyClear UV Resin 300g — High Viscosity
Features: HeyClear offers a high-viscosity UV resin in a 300g setup with strong hardness after curing and low odor. It’s designed for doming, sealing, and casting on crafts with crisp transparency and good scratch resistance. The resin’s slow flow helps maintain intricate shapes and reduces drips, making it suitable for jewelry, small sculptures, and crystal-like coatings where a rigid, clear finish is required.
Liquid Glass Deep Pour Epoxy — 0.75 Gallon, 96 oz Kit
Features: While marketed as a deep pour resin, this kit is designed for 2-4 inch pours with a focus on large projects like river tables and trays. It promises bubble-free curing through a low-viscosity formulation that reduces air pockets and maintains a crystal-clear, UV-resistant finish. It aims for high structural integrity and long-lasting gloss, ideal for those pursuing substantial, deep cast works.
Buying Guide: Key Considerations For High Viscosity Epoxy Resin
- Project scale and pour depth: High-viscosity resins are best for tall or thick pours where flow needs to be controlled. For river tables or large surfaces, consider formulas designed for 2-4 inch pours or thicker to minimize layering.
- Curing time and working window: Look for resin kits with a workable pot life long enough to shape and spread the coating, followed by a reasonable cure time. Temperature can affect both working time and final hardness.
- Clarity and yellowing resistance: A crystal-clear finish with UV resistance will prevent yellowing over time, especially on sun-exposed furniture or crafts that will be displayed prominently.
- Odor and safety: Low-odor formulations make indoor use more comfortable. If the product is food-safe, ensure it’s used per directions for compatible applications like coasters and serving surfaces.
- Reactivity and compatibility: Some products are optimized for tumblers, while others are ideal for tabletops, coasters, or jewelry. Confirm compatibility with your substrate (wood, concrete, metal, glass, resin art, etc.).
- Bubble control and self-leveling: Bubble-free and self-degassing features reduce surface defects. Self-leveling resins help avoid manual adjustments during the pour.
- Availability of accessories: Some kits include mixing cups, gloves, or spreaders, which can be convenient for beginners. Check what’s included and plan for any extra tools you might need.
- UV resistance and finish durability: If UV stability is critical, choose resins specifically labeled UV resistant with a high gloss finish to preserve clarity and prevent surface micro-scratches.
