Liquid silicone rubber operations
Firstly process and prepare the model mold or the product to be
duplicated, take a certain amount of the silicon rubber, add 2-3%
solid curing agent, and mix evenly and they are ready for use. One
pair of mold can be solidified and formed in 2-3 hours.
(Note: our company does not recommend you to add silicon oil. If a
special soft silicone mold or fine detailed and complex patterns
products are required, 5%-10% silicone oil can be added to soften
the mold for easy demold.)
