How to make the silicone mold? 1. Make sure the surface of the original is clean and free of loose material. 2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container. 3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage. 4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base. 5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original 6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.
