Product Description
EpoxAcast™ 690
EpoxAcast™ 690 is an UV resistant clear casting epoxy resins suitable for a variety of industrial and art related projects requiring a rigid, clear finished casting. EpoxAcast™ 690 features a very low viscosity for easy mixing and minimal bubble entrapment. Castings cure with negligible shrinkage and are very hard and strong. Resin can be colored with UVO™ or IGNITE™ colorants. Cast Magic™ and Glow Worm™ powders can also be added to create amazing casting effects.
Econ™ 60
Econ™ 60 is an economical and fast curing Shore 60A urethane rubber. It has no odor, features a convenient 1A:1B by volume mix ratio and a low viscosity for easy mixing and pouring. Working time is about 6 minutes and handling time is 4 hours at room temperature. Translucent clear amber color(light passes through) makes Econ™ 60 easy to color with SO Strong™, UVO™ or IGNITE™ colorants. Econ™ 60 is used to make limited run production rubber molds, stamping pads, rubber prototype parts, rubber props and pour-in-place gaskets for industrial equipment. It is also suitable for coating fabrics.
