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.

Platinum (0) -1,3-divinyl-1,1,3,3-tetramethyldisiloxane is a catalyst containing platinum element, also known as platinum metal catalyst. It has two vinyl functional groups and can catalyze crosslinking reactions between silicone rubber and other silicon-based materials. This catalyst is very important in organic silicon chemistry and silicone rubber industry due to its high activity and selectivity. It is commonly used to control the crosslinking process and improve the performance of materials.
