Abstract

A peelable paint composition for forming a peelable coating on a substrate is provided. The peelable paint composition includes water, a polysiloxane resin, and a film-forming resin that includes a component selected from the group consisting of styrene-butadiene copolymer, polyvinyl butyral, and combinations thereof.

First claim

What is claimed is:

1. A peelable paint composition for forming a peelable coating on a substrate, the peelable paint composition comprising:
a polysiloxane resin that includes polysiloxane with functional groups and polyglycol ether groups;
a film-forming resin that includes a component selected from the group consisting of styrene-butadiene copolymer, polyvinyl butyral, and combinations thereof; and
water.

2. The peelable paint composition of claim 1 , wherein a weight ratio of the film-forming resin to the polysiloxane resin is from 5:1 to 40:1.

3. The peelable paint composition of claim 1 , wherein a weight ratio of the film-forming resin to the polysiloxane resin is from 8:1 to 15:1.

4. The peelable paint composition of claim 1 , wherein the film-forming resin includes a styrene-butadiene copolymer.

5. The peelable paint composition of claim 1 , wherein the styrene-butadiene copolymer is a random copolymer of about 50 to 85 weight percent butadiene and about 50 to 15 weight percent styrene.

6. The peelable paint composition of claim 1 , wherein the styrene-butadiene copolymer is a random copolymer of about 70 to 80 weight percent butadiene and about 30 to 20 weight percent styrene.

7. The peelable paint composition of claim 1 , wherein the polysiloxane resin includes a polyether functional polydimethylsiloxane.

8. The peelable paint composition of claim 1 , wherein:
the polysiloxane resin is present in an amount from about 1 to 20 weight percent of the total peelable paint composition; and
the film-forming resin is present in an amount from about 50 to 75 weight percent of the total peelable paint composition,
with the balance being one or more paint additives and water.

9. The peelable paint composition of claim 8 , wherein the one or more paint additives are selected from the group consisting of titanium oxide, pigment extenders, matting agents, rheology modifiers, surfactants, defoamers, organic solvents, pH adjusters, UV stabilizers, dispersants, coalescents, biocides, opaque polymers, thickeners, mildewcides, and combinations thereof.

10. A peelable paint composition for forming a peelable coating on a substrate, the peelable paint composition comprising:
a reactive polysiloxane resin that is completely miscible with water;
a film-forming resin that includes a component selected from the group consisting of styrene-butadiene copolymer, polyvinyl butyral, and combinations thereof;
titanium oxide; and
water.

11. The peelable paint composition of claim 10 , wherein the weight ratio of the film-forming resin to the polysiloxane resin is from 5:1 to 40:1.

12. The peelable paint composition of claim 10 , wherein the film-forming resin includes a styrene-butadiene copolymer.

13. The peelable paint composition of claim 10 wherein the reactive polysiloxane resin includes a polyether functional polydimethylsiloxane.

14. The peelable paint composition of claim 10 wherein the reactive polysiloxane resin includes polysiloxane with functional groups and polyglycol ether groups.

15. The peelable paint composition of claim 10 , wherein:
the reactive polysiloxane resin is present in an amount from about 1 to 20 weight percent of the total peelable paint composition; and
the film-forming resin is present in an amount from about 50 to 75 weight percent of the total peelable paint composition; and
titanium oxide is present in an amount of 3 to 15 weight percent of the total peelable paint composition,
with the balance being one or more paint additives and water.

16. The peelable paint composition of claim 15 , wherein the one or more paint additives are selected from the group consisting of pigment extenders, matting agents, rheology modifiers, surfactants, defoamers, organic solvents, pH adjusters, UV stabilizers, dispersants, coalescents, biocides, opaque polymers, thickeners, mildewcides, and combinations thereof.

17. A peelable paint composition for forming a peelable coating on a substrate, the peelable paint composition comprising:
a polysiloxane resin that includes a polyether functional polydimethylsiloxane or an organosiloxanyl with polyalkylene glycol;
a film-forming resin that includes styrene-butadiene copolymer; and
water.

18. The peelable paint composition of claim 17 , wherein the weight ratio of the film-forming resin to the polysiloxane resin is from 5:1 to 40:1.

19. The peelable paint composition of claim 17 further comprising titanium oxide.
