Hydroxypolysiloxane

COSiL®F series hydroxy polysiloxane is a hydroxyl-terminated polydimethylsiloxane. Hydroxy polysiloxane is a series of functional polymers with different terminal hydroxyl content depending on viscosity. It 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 oil can also be used as a reactive diluent to adjust the overall viscosity of the formulation. Hydroxy silicone oil series products can undergo condensation reactions with crosslinkers (such as alcohol silanes, lipid silanes, and acidic silanes), and tin catalysts can promote the reaction.
