Platinum-divinyltetramethyldisiloxane complex，68478-92-2
Hydrosilane addition catalyst for modifying silicone oil:
1. Hydrosilane addition reaction is a very important synthesis method in organosilication, which is widely used in the production of synthetic defoamer, levelling agent and textile auxiliaries.
2. It refers to the addition reaction between the material containing silicone hydrogen bond (Si-H) and the material containing unsaturated bond (H2C=CH-C-), so that a large number of organosilicon derivatives can be obtained, so the catalyst in the reaction plays an extremely critical role.
Our company has a close technical cooperation with Fudan University, in the silane hydrogen addition has a deep foundation and experience, now developed a KP series of new high efficiency catalyst, especially suitable for the synthesis of modified silicone oil.
