Dispersions of silicate particles are formed in a polyol phase. The polyol, an alkoxysilane, water and catalyst are combined and reacted under specific temperature conditions to form the silicate particles in-situ in a liquid polyol phase. The dispersions are characterized in having excellent stability.

Method of making dispersions

A foam control agent comprising a linear polyorganosiloxane-polyoxyalkylene block copolymer comprising a single block of polyorganosiloxane having a DP of from 10 to 200 and a single block polyoxyalkylene block having a DP of from 2 to 60.

Linear silicone polyether foam control agent

Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.
