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.
TASK™ 11
TASK™ 11 urethane casting resin is a semi-rigid plastic (has some flexibility) that is strong and very tough. Originally developed for high impact tooling (drop hammer punch), TASK™ 11 also offers good abrasion and chemical resistance and is ideal for a variety of industrial applications.
This product is suitable for some FDA/USDA applications - dry food contact only.
TASK™ 11 applications include making abrasion resistant parts, foundry patterns, encapsulation, roller facings, metal bonding and vibration pads.
