Products Description

Additive Mold silicone

Additive mold silicone is usually called two-component room temperature vulcanization molding silicone. The A and B components of

the silicone are liquid, containing platinum thixotropy, catalyst or other additives, and can be cured at room temperature or at

elevated temperature after mixing.

* Metal crafts, alloy car and other precision mold manufacturing

* Molding of epoxy resin, polyester resin, polystyrene, vinyl plastic, paraffin, etc.

* Manufacture of molds for large cement components, cultural stones, concrete and other products

* Design and production of high-precision hand-plate models, automotive development, power airfoil

* Food grade mold making

* Customized Product
