EpoxAcast 650 BLACK Quart 3 Lbs (800666)
EpoxAcast® 650 Black is a mineral filled general purpose casting epoxy that is low cost and versatile. It features a low mixed viscosity for minimal bubble entrapment. Choose Fast, Medium or Slow catalyst to fit your project. You can also use HT Hardener to give your castings higher heat resistance. EpoxAcast® 650 is used for making hard dies for metal stamping as well as patterns and fixtures. It is also used for electrical encapsulation to extend the life cycles and enhance the performance of potted electronic devices. The high compressive strength of EpoxAcast® 650 makes it ideal for making stamping dies for production pressing of metal ornaments.
