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.

Product Usage

* 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

Product Feature

* Food grade, non-toxic and odorless, RoHS certification
* High tensile and tear strength, multiple use, difficult to deform
* Good flowability, easy infusion, can be cured at room temperature or at elevated temperature, easy to operate.
* Deep vulcanization is possible regardless of the thickness of the product.
* Low line shrinkage (≤0.1%) and high precision of reproduction products.
* Excellent chemical resistance, high temperature resistance up to 250℃
