Product Highlights

USi-OH Polymers are a series of silanol functional fluids with various viscosities and silanol contents. The low viscosity grades can be used as reactive diluents for high viscosity polymers to adjust the overall viscosity of the formulation. They have excellent stability and can be used with catalytic amounts of ammonium carbonate to treat reinforcing fillers in-situ. USi-OH products are pure and do not contain any plasticizers or additives. Curing of the USi-OH series can be achieved by all usual condensation crosslinkers (i.e. alkoxy silanes, oxime silanes, acetoxy silanes) in conjunction with catalysts - the use of dibutyl tin dilaurate or stannous octoate have been found effective as catalysts for these reaction.
