1. Mouldmaking rubber Description:
Mouldmaking rubber is two-component material consiting of part A silicone rubber, part B catalyst. It cures at room temperature by condensation raction.
A range of materials can be cast into a cured silicone molds, like plaster, gypsum, polyurethane, polyester, resin, cement, wax and so on are usually used.
2. Moldmaking silicone FEATURES:
1). Two-part silicon rubber:flowable liquid silicon and curing agent.
2). Cures at room temperature within 3-5 hours.
3). An exceptional fluidity and good operability, easy to demold.
4). Good tensile and tear strength, low shrinkage.
5). High duplication times.
