1.Product features

Product Name: Platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane

Synonym:Karstedt catalyst, Pt Catalyst, Platinum catalyst, Si-H additive catalyst solution

Cas No.:68478-92-2

Km-415 Platinum catalyst is also named Karstedt's catalyst,which is an organoplatinum compound derived from divinyl-containing disiloxane. This coordination complex is widely used in hydrosilylation catalysis. It is a colorless liquid that is generally assumed to be a mixture of related Pt(0) alkene complexes. 

It can catalyze Si-H addition reaction and inhibit the side reactions accompanying Si-Vi and Si-H reactions . It overcomes the phenomenon of yellow or blackening in the use of other catalysts. Curing speed, high efficiency, low consumption; Also can prepare high transparent colorless products, the Transparency can meet the standards of similar foreign products in Japan, the United States, Germany and other countries.
