Polysiloxane Modified Polyisocyanates for Use in Coatings

A method of manufacturing an isocyanate-terminated polysiloxane material comprising the steps of:

• providing a silanol functional polysiloxane compound having the following structure:
• wherein n≧1 and each R individually correspond to methyl, phenyl or alkyl groups;
• providing an isocyanate having at least two isocyanate groups;
• providing a reaction catalyst;
• reacting the polysiloxane with the isocyanate in the presence of the catalyst for a period of time sufficient to produce a isocyanate-terminated polysiloxiate material.

A coating kit comprising:

• a isocyanate-terminated polysiloxane curing agent;
• a isocyanate-reactive polymer;
• and
• wherein the isocyanate-terminated polysiloxane curing agent and the isocyanate-reactive polymer are packaged separately.
