Linear vinyl silicone oil IOTA 273
DESCRIPTION:
1. This product is the end vinyl polydimethylsiloxane, active intermediate material.
2. The product has common performance of methyl silicone oil.
3. Two ends of vinyl is too active to react with hydrogen silicone with catalyst, also can participate in a variety of other reactions.
4. it has better intermiscibility with organic material comparing to methyl silicone oil, easy to compatibility with other organic materials.
5. For containing lively double bond, easy to have reaction with organic material such as polyurethane etc.
