100 pbw to 100 pbw
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.
Apply 2 epoxy gel coats (RSC-301X & SC-150-N), then 2 layers of style 7500 fiberglass cloth with clear laminating resin (LR-100 & LH-101), then 1/4″ to 1/2″ thick DT-2000 A & B. Next apply 2 layers of 7500 fiberglass cloth with laminating resin. This application will yield a very lightweight sandwich mold.
