Abstract
A silicone modified organic polymer is shown and described herein. The silicone modified organic polymer is a reaction product of a composition comprising an organic polyol, a silicone resin, and a hydrophilic silane. The hydrophilic silicone modified resin is directly dispersible in water. An aqueous dispersion of the silicone modified organic polymer is suitable for use as an additive in a coating composition.

A silicone modified organic polymer comprising a reaction product of:
- an organic polyol;
- a silicone resin;
- and
- a hydrophilic silane or an oligomer thereof;
- wherein the silicone resin is an organopolysiloxane of the formula:
- MDTQ
- where
- M is R1R2R3SiO1/2
- D is R4R5SiO2/2
- T is R6SiO3/2;
- Q is SiO4/2;
- and
- where R1, R2, R3, R4, R5, and R6 are independently selected from a monovalent hydrocarbon radical, OR7 or a divalent hydrocarbon radical, OR8O, where R7 is independently selected from H or a C1-C10 hydrocarbon radical and R8 is independently selected from C1-C10 divalent hydrocarbon radical.
