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™ 15

TASK™ 15 is a premium performance urethane resin that has very high impact strength, even when cast in thin-wall sections. Pot life is 6 minutes and handling time 60 minutes at room temperature. Resin cures with negligible shrinkage.

Vibrant colors are possible by adding small amounts of SO-Strong™ tints, UVO™ pigments or IGNITE™ fluorescent colors.

Plastic fully cures with negligible shrinkage and can be machined, sanded and/or painted. TASK™ 15 features a gradual cure profile, making it ideal for rotational casting applications (making hollow parts).

Applications include making very tough prototype parts and limited run production castings as well as rotationally cast parts such as mannequins.
