Product Description
EpoxAcast™ 655 + 103 Hardener
EpoxAcast™ 655 (formerly Metalset™ A-30) is a versatile aluminum filled castable epoxy resin that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in³ / 8,390 cm³.
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.
