Properties
Hydroxyl silicone oil is the organosilicon material polymerized by siloxane monomer terminated with hydroxyl groups. Conventionally the hydroxyl silicone oil with viscosity above 1500 mpa.s is called 107silicone sealant/adhesive.
Apart from the general functions of hydroxyl silicone oil, this product possesses the reactivity of the hydroxyl group that can be made into some new material or crosslinked as elastomer(or film body). This product is a colorless transparent liquid with excellent electrical insulation, high and low-temperature resistance, high flash point, low freezing point, long-term adaption to temperatures from -50°C to 250°C, low viscosity-temperature coefficient, high compression rate, low surface tension, good water repellent and moisture resistance, chemical inertness, physical inertness.
