BC-8340 is a two-part polyurethane molding system. BC-8340 is mixed one-to-one by volume (or 100 Iso Side A to 95 Curative Side B by weight) and cures at room temperature. BC-8340 contains no fillers and cures to a firm (Shore A40 4), medium amber rubber.

BC-8340 is used to make molds of detailed masters that contain moderate undercuts. Some of the most common uses are molds for point-of-purchase displays, rapid prototypes, special effects, taxidermy, and sculpture reproductions.
