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. Different hardener speed options are available depending on your project requirements. Maximum heat resistance is achieved using HT HIGH TEMP hardener (up to 225°F/108°C).

Cured EpoxAcast® 655 epoxy has high physical properties and is used for a variety of applications including making hard tooling, vacuum forming dies/molds, injection molds, foundry patterns, jigs and fixtures and metal forming dies.  Depending on project requirements, Part A Base can be mixed with 101 FAST, 102 MEDIUM, 103 SLOW or HT HIGH TEMP hardeners.
