Abstract

A peelable paint composition includes a release agent having a component selected from the group consisting of soy lecithin, a polysiloxane, silicone polyether, and combinations thereof. The peelable paint composition further includes a film-forming resin that includes a component selected from the group consisting of natural rubber, styrene-butadiene copolymer, polyvinyl butyral, a vinyl acetate-ethylene copolymer, vinyl acrylic copolymer that includes styrene, acrylic styrene copolymer, and combinations thereof. The peelable paint composition can further include a number of optional additives. Water makes up the balance of the paint composition.

Claims (42)

1 . A peelable paint composition for forming a peelable coating on a substrate, the peelable paint composition comprising:

soy lecithin as a release agent;

a film-forming resin that includes a component selected from the group consisting of natural rubber, styrene-butadiene copolymer, polyvinyl butyral, a vinyl acetate-ethylene copolymer, acrylic styrene copolymer, and combinations thereof; and

water.

2 . The peelable paint composition of claim 1 wherein the weight ratio of the film-forming resin to the release agent is from about 3:1 to 50:1.

3 . The peelable paint composition of claim 1 wherein the film-forming resin is present in an amount from about 30 to 75 percent of the total weight of the peelable paint composition.

4 . The peelable paint composition of claim 1 wherein the release agent is present in an amount from about 1 to 8 percent of the total weight of the peelable paint composition.

5 . The peelable paint composition of claim 1 , wherein the film-forming resin includes natural rubber.

6 . The peelable paint composition of claim 5 wherein the natural rubber is provided as a latex that includes poly (cis-1,4-isoprene) in an amount of about 40 to 80 weight percent of the total weight of the latex.

7 . The peelable paint composition of claim 6 wherein the latex is treated with an agent to remove protein.

8 . The peelable paint composition of claim 5 wherein the natural rubber is present in an amount from about 35 to 85 weight percent of the total weight of the peelable paint composition.

9 . The peelable paint composition of claim 1 wherein the film-forming resin includes a component selected from the group consisting of styrene-butadiene copolymer, a vinyl acetate-ethylene copolymer, vinyl acrylic copolymer that includes styrene, acrylic styrene copolymer, and combinations thereof and wherein the peelable paint composition does not include any polyvinyl butyral.

10 . The peelable paint composition of claim 1 , wherein a weight ratio of the film-forming resin to the soy lecithin is 10:1 to 30:1.

11 . The peelable paint composition of claim 1 , wherein the acrylic styrene copolymer each includes 15 to 50 weight percent styrene.

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

13 . The peelable paint composition of claim 12 , 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.

14 . The peelable paint composition of claim 1 , wherein the release agent is a polysiloxane that includes a polyether functional polydimethylsiloxane.

15 . The peelable paint composition of claim 14 , wherein the polysiloxane includes polysiloxane with functional groups and polyglycol ether groups.

16 . The peelable paint composition of claim 1 , further including one or more paint additives.

17 . The peelable paint composition of claim 16 , 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, matting agents, opaque polymers, thickeners, mildewcides, and combinations thereof.

18 . The peelable paint composition of claim 17 , wherein the one or more paint additives include a low shear rheology modifier and a high shear rheology modifier.

19 . A peelable paint composition for forming a peelable coating on a substrate, the peelable paint composition comprising:

natural rubber as a film-forming resin, wherein the natural rubber is provided as a latex that includes poly (cis-1,4-isoprene) in an amount of about 40 to 80 weight percent of the total weight of the latex and wherein the latex is treated with an agent to remove protein;

a polysiloxane; and

water.

20 . The peelable paint composition of claim 19 , wherein the polysiloxane is a polysiloxane defoamer.

21 . The peelable paint composition of claim 20 , wherein the polysiloxane defoamer is present in an amount from about 0.1 to 2 weight percent of the total weight of the peelable paint composition.

22 . The peelable paint composition of claim 19 , wherein the polysiloxane is a release agent.

23 . The peelable paint composition of claim 22 , wherein the release agent is a polysiloxane that includes a polyether functional polydimethylsiloxane.

24 . The peelable paint composition of claim 22 , wherein the polysiloxane includes polysiloxane with functional groups and polyglycol ether groups.

25 . The peelable paint composition of claim 22 , wherein the polysiloxane is a polydimethylsiloxane.

26 . The peelable paint composition of claim 22 , wherein the release agent is present in an amount from about 2 to 12 weight percent of the total weight of the peelable paint composition.

27 . The peelable paint composition of claim 19 wherein the natural rubber is provided as a latex that includes poly (cis-1,4-isoprene) in an amount of about 40 to 80 weight percent of the total weight of the latex.

28 . The peelable paint composition of claim 19 , wherein the natural rubber is present in an amount from about 35 to 85 weight percent of the total weight of the peelable paint composition.

29 . The peelable paint composition of claim 19 , further comprising one or more paint additives.

30 . The peelable paint composition of claim 29 , 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, matting agents, opaque polymers, thickeners, mildewcides, and combinations thereof.
