Abstract
The present invention is directed to a sealing composition comprising: (a) a polysiloxane; (b) a reactive polysiloxane comprising at least one reactive functional group; and (c) water; wherein the weight ratio of polysiloxane to reactive polysiloxane is from 2.7:1 to 4:1. Also disclosed are coated substrates and methods of coating a substrate.
Claims26
A sealing composition comprising:
- (a) a polysiloxane, wherein the polysiloxane comprises alkoxy groups;
- (b) a reactive polysiloxane comprising at least one reactive functional group;
- and
- (c) water;
- wherein the solids weight ratio of polysiloxane to reactive polysiloxane is from 1.7:1 to 4:1.
A method of coating a substrate comprising applying a sealing composition to at least a portion of a surface of the substrate, wherein the sealing composition comprises:
- (a) a polysiloxane;
- (b) a reactive polysiloxane comprising at least one reactive functional group;
- and
- (c) water;
- wherein the solids weight ratio of polysiloxane to reactive polysiloxane is from 1.7:1 to 4:1.
A substrate at least partially coated by a sealing composition, wherein the sealing composition comprises:
- (a) a polysiloxane;
