3:1 Low Viscosity Bubble Free Fast Cure Clear Epoxy Resin
Model: 312AB-8 Mixing Ratio: 3:1 by weight
312AB-8 is a 3:1 low-viscosity 2 part epoxy designed for small casting, badge coating, keychains, cards and miniature mold work. Its thin flow helps the resin move into fine details and shallow surfaces while reducing trapped air during pouring. The formula self-levels smoothly and cures into a clear glossy surface with reliable hardness. It suits silicone molds, charms, small ornaments and coated decorative pieces where bubble control and clean detail matter. Fast curing also helps shorten handling time for small batches without sacrificing clarity.
