| About |
|---|
| BC8360 is a two-part polyurethane molding system. BC8360 is mixed one-to-one by volume (or 100A-to-95B by weight) and cures at room temperature. BC8360 contains no fillers and cures to a firm (Shore A60 ± 4), medium amber rubber. Applications BC8360 is used to make molds of detailed masters that contain shallow undercuts. Some of the most common uses are concrete formliners and to make molds for point-of-purchase displays, rapid prototypes, special effects, taxidermy, and sculpture reproductions.&& |
