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

Advantage of platinum catalyst

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

2. Good stability

3. Strong toxic resistance

4. No side products after using our platinum catalyst

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

6. Friendly environmental, no toxic gas released in vulcanizing processing
