Abstract

A coating composition for forming abrasion-resistant, high clarity coatings is described. It has been found that a macrocrystalline or single crystal miner al abrasive can be added at high levels, about 5 to about 80 percent by weight, to art-recognized film-forming resin compositions for producing coatings exhibiting exceptional abrasion resistance and clarity. Such a coating composition is useful for application to surfaces including wood, vinyl, til e, rubber modified cement, marble, metal, plastic, and laminated surfaces.</SDO AB>

Claims (31)

1. A coating composition for forming abrasion-resistant coatings of high clarity, said coating composition comprising a film-forming resin composition and a mineral abrasive in macrocrystalline or single crystalline form in an amount effective to impart abrasion resistance to the coating.
2. The composition of claim 1 wherein the mineral abrasive is an aluminum oxide.
3. The composition of claim 2 wherein the aluminum oxide is an electrofused aluminum oxide.
4. The composition of claim 2 wherein the aluminum oxide forms about 5 to about 80 weight percent of the coating.
5. The coating composition of claim 1 wherein the mineral abrasive is a silicon dioxide.
6. The composition of claim 5 wherein the silicon dioxide forms about 5 to about 80 weight percent of the coating.
7. The composition of claim 1 wherein the single crystal mineral abrasive forms a crystal of about 1 micron to about 500 microns in size.
8. The composition of claim 1 wherein the film-forming resin composition comprises a thermosetting resin.
9. The coating composition of claim 8 wherein the thermosetting resin comprises epoxy resins, acrylic resins, polyester resins, polycarbonate resins, melamine-formaldehyde resins, or polyurethane resins.
10. The coating composition of claim 9 wherein the thermosetting resins comprise a polymer crosslinked through the use of an aminoplast.
11. The composition of claim 1 wherein the film-forming resin composition comprises a UV-curable resin.
12. The composition of claim 11 wherein the UV-curable resin comprises olefin functional monomers and olefin functional oligomers or polymers.
13. The composition of claim 12 wherein the olefin functional oligomers or polymers comprise polyurethanes, cellulosic acrylic butyrates, nitrocellulosic polymers, polyesters, acrylic polymers, or blended or grafted combinations thereof.
14. The composition of claim 1 wherein the film-forming resin composition comprises a thermalplastic resin.
15. The composition of claim 14 wherein the thermalplastic resin comprises a nitrocellulose resin, an alkyd resin, a polyester resin, an acrylic resin, a vinyl acrylic resin, a styrene acrylic resin, a urethane, or a natural product.

26. The improved method of claim 24 wherein the aluminum oxide forms about 5 to about 20 percent by weight of the top coat.
27. The improved method of claim 16 wherein the surface is selected from the group consisting of a wood surface, a vinyl surface, a tile surface, a rubber modified cement surface, a marble surface, a metal surface, and a plastic surface.
28. An abrasion-resistant laminate comprising a base layer and at least one additional layer wherein the surface of said additional layer is finished with a coating composition comprising a film-forming resin composition and a macrocrystalline or single crystalline mineral abrasive in an amount effective to impart abrasion resistance to the surface finish.
29. A method of finishing the surface of a laminate comprising the step of applying to at least one layer of the laminate a coating composition comprising a film-forming resin composition and a macrocrystalline or single crystalline mineral abrasive in an amount effective to impart abrasion resistance to the surface finish.
30. A paper composition for forming an abrasion resistant surface of high clarity on a laminated composite said composition comprising paper impregnated or coated with a coating composition comprising a film-forming resin and about 5 to about 60 percent by weight of a mineral abrasive in macrocrystalline or single crystalline form.
31. A coating composition for forming abrasion-resistant coatings of high clarity, said coating composition comprising a film-forming resin composition and a mineral abrasive in macrocrystalline or single crystalline form wherein said mineral abrasive forms about 5 up to about 60 weight percent of the coating and wherein the coating composition exhibits about 70 percent clarity measured according to the ASTM® E430 Standard.
