Product Description

Hydroxypolysiloxane
The COSIL F series of hydroxypolysiloxanes is a hydroxyl terminated polydimethylsiloxane. It is a series of functional polymers with different viscosities and different contents of terminal hydroxyl groups. Low-viscosity polymers can be used for filler surface treatment and anti-structuring additives for high-temperature adhesives, and can also be used in room-temperature adhesive formulations. Low-viscosity hydroxy silicone oils can also be used as reactive diluents to adjust the overall viscosity of the formulation.
