Description: DT-2000 A & B is a lightweight, color coded, two component, 1 to 1 mix epoxy system. When mixed together it forms a soft, dough-like consistency that cures at room temperature. DT-2000 A& B exhibits low exotherm thus providing excellent for quick light weight back-up supporting structure for large parts.
