Platinum catalyst for addition liquid silicone

Product Description


Introduction of platinum catalyst 

The platinum catalyst is a high reactive and high catalytic platinum catalyst. It can catalytic the addition reaction without side-product of Si-Vi and Si-H efficiently. And the product is with advantages of good stability and strong toxic resistance which avoid appearing of the atrament in storage or processing and decrease the influence of nitrogen, vulcanization containing substance.


Advantage of platinum catalyst 

High reactivity, simple vulcanizing(can vulcanize at low temperature)

Good stability

Strong toxic resistance

No side products

Less influence in transparency and high transparent products can be made.

Friendly environmental, no toxic gas released in vulcanizing processing


Application of platinum catalyst 

1.Be a catalyst for addition liquid silicone rubber, silicone gel, addition solid silicone rubber, LED encapsulant and inks of silicone

2.Be a catalyst for compounding of polyether silicone oil and aminosiliconoil

3.Can be used in other situations that addition reaction of silicone-hydrogen



Typical properties of platinum catalyst 













Transparent liquid
