GENERAL DESCRIPTION: HHTD A & B is a lightweight, color coded, high heat, two component epoxy system. When mixed together it forms a soft dough-like consistency that gels at room temperature. Then post cure.
RECOMMENDED USE: Apply two high temperature epoxy gel coats (HSC-905 & HT-9234), then 2-4 layers of fiberglass cloth (6 oz. TO 10 oz.) with high temperature laminating resin (HTR-350 & HT-9234). Then apply HHTD A & B to about 1/4" to 3/4" thick, making sure resin and hardener are mixed thoroughly. Then 2-4 layers of fiberglass cloth with high temperature laminating resin. This application will yield a very lightweight sandwich mold.
