rubber molds stone veneer with low shrinkage

1.Description of rubber molds stone veneer with low shrinkage

rubber molds stone veneer with low shrinkage are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage.

The mixing ratio between Part A and Part B can be 10:1 or 1:1.
