A flowable liquid with consistent quality in whatever color. Prt A is a flowable liquid, part B is the curing agent. Prepare the original mold or product to copy, add 2%-2.5% curing agent to certain amount of silicon, and mix them evenly and they are ready for use.

The product is intended principally for manual molding and small quantity product duplication.
