Abstract

The present application provides a primer composition, a method for treating a wet or damp surface with the primer composition, and a method to improve the adhesion of pavement markers to wet or damp surfaces. The primer composition comprises about 5 weight percent to about 90 weight percent of the reaction product of: (i) about 30 to about 70 parts by weight of an (meth)acrylate ester wherein the (meth)acrylate ester; (ii) about 70 to about 30 parts by weight of a hydrophilic acidic comonomer; and (iii) about 10 to about 100 parts based on 100 parts of the sum of the (meth)acrylate ester and the hydrophilic acid comonomer, of a plasticizer; dissolved in about 10 to about 95 weight percent of at least one organic solvent.

First claim

What is claimed is:

1. A method for treating a wet or damp surface comprising:
providing a primer composition comprising:
(a) about 5 weight percent to about 90 weight percent of the reaction product of:
(i) about 30 to about 70 parts by weight of an (meth)acrylate ester;
(ii) about 70 to about 30 parts by weight of a hydrophilic acidic comonomer; and
(iii) about 10 to about 100 parts based on 100 parts of the sum of the (meth)acrylate ester and the hydrophilic acid comonomer, of a plasticizer; and

(b) from about 10 to about 95 weight percent of an organic solvent;

applying the primer composition to a wet or damp surface; and
allowing the primer composition to dry.

2. The method of claim 1 , wherein the primer composition is applied to the wet or damp surface by means of casting, spraying, rolling, coating, spreading, painting, covering, layering, smearing or brushing.

3. The method of claim 1 , wherein the wet or damp surface includes at least one of brick, pavingstone, asphalt, wood, wood composite, polymer, concrete or bituminous material.

4. The method of claim 1 , wherein the (meth)acrylate ester monomer is selected from a group consisting of n-butyl acrylate, 2-ethylhexyl acrylate, isooctyl acrylate, lauryl acrylate and mixtures thereof.

5. The method of claim 1 , wherein the hydrophilic acidic monomer is selected from a group consisting of ethylenically unsaturated carboxylic acids, ethylenically unsaturated sulfonic acids, ethylenically unsaturated phosphonic acids and mixtures thereof.

6. A method for applying a pavement marker to a wet or damp surface comprising:
providing a primer composition comprising:
(a) about 5 weight percent to about 90 weight percent of the reaction product of:
(i) about 30 to about 70 parts by weight of an (meth)acrylate ester;
(ii) about 70 to about 30 parts by weight of a hydrophilic acidic comonomer; and
(iii) about 10 to about 100 parts based on 100 parts of the sum of the (meth)acrylate ester and the hydrophilic acid comonomer, of a plasticizer; and

(b) from about 10 to about 95 weight percent of an organic solvent;

applying the primer composition to a wet or damp surface;
allowing the pavement marker to dry; and
applying a pavement marker to the surface.

7. The method of claim 6 , wherein the pavement marker is at least one of a liquid pavement marking composition, a pavement marking tape, and a raised pavement marker.

8. The method of claim 6 , wherein the pavement marker includes an adhesive that contacts the treated surface.

9. The method of claim 8 , wherein the adhesive is one of a pressure sensitive adhesive, a contact adhesive, and a hot-melt adhesive.

10. The method of claim 6 , wherein the primer composition is applied to the wet surface by means of casting, spraying, rolling, coating, spreading, painting, covering, layering, smearing or brushing.
