BE769 Intermediate Toughened Epoxy Tooling & Modelling Board

BE769 is a toughened epoxy modelling material known for its superior finish, dimensional stability and its ability to maintain tolerances even after being subjected to temperature variations. For example, direct tooling where it helps maintain high detail quality following repetitive thermal-cycling.
