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 bubble-free epoxy resin for charms, badges, coated cards and miniature mold pieces. Its thin formula moves quickly across fine details and shallow surfaces, helping reduce trapped air during pouring and leveling. The resin suits small projects that need a clear, glossy finish without heavy post-correction. Fast curing shortens the wait between pouring and demolding, while the cured material keeps stable hardness for handling and display. This product fits silicone molds, keychain parts, badge coatings and mini decorative pieces where fluidity and bubble control matter.
