Product Description

EpoxAcast™ 690

EpoxAcast™ 690 is a clear casting epoxy resin suitable for a variety of industrial and art-related projects requiring a rigid, clear finished casting. It is mixed 100A:30B by weight (gram scale required) and features a very low viscosity for easy mixing and minimal bubble entrapment. Working time is 5 hours and cure time is 24 hours at room temperature. Castings cure with negligible shrinkage and are very hard and strong. Resin can be colored with UVO™ or IGNITE™ colorants. This product is not moisture sensitive and can be used in humid environments. Recommended casting thickness maximum per layer is 3/8 in. / 0.95 cm.
