Patent ID: 7247351

Claim:
A method of applying a silicone modified polyurea to a substrate, comprising: combining at least one amine selected from the group consisting of primary aliphatic amines, primary cyclo-aliphatic, secondary aliphatic amines, primary aromatic amines, and secondary aromatic amines, and mixtures thereof, with at least one epoxy functional silicone to form a solution; reacting said solution to form a polyol prepolymer chain extender, wherein said reacting comprises heating said solution at a temperature in the range of from 130° F. to 210° F. for a time period sufficient to substantially react all of said polyol prepolymer chain extender; cooling said polyol prepolymer chain extender; and applying said polyol prepolymer chain extender and at least one polyisocyanate simultaneous to said substrate to form a silicone modified polyurea on said substrate.
