Coatings containing micronized polymers as matting agents
A matte finish coating for application to a substrate includes in a mixture a coating substance and a micronized polymer matting agent. The matte finish coating comprises the micronized polymer matting agent in an amount, by overall weight of the matte finish coating, of about 0.5% to about 15%.
1. A matte finish coating for application to a substrate, comprising in a mixture:
a coating substance; and
a non-emulsified micronized polymer matting agent comprising a micronized high-density polyethylene (HDPE) polymer or a micronized low-density polyethylene (LDPE) polymer wherein the HDPE or LDPE has an average particle diameter of about 6 microns to about 30 microns; and
wherein the matte finish coating comprises the micronized polymer matting agent in an amount, by overall weight of the matte finish coating, of about 0.5% to about 15%.
2. The matte finish coating of claim 1 , wherein the matte finish coating comprises the micronized polymer matting agent in an amount, by overall weight of the matte finish coating, of about 1.0% to about 12%.
3. The matte finish coating of claim 2 , wherein the matte finish coating comprises the micronized polymer matting agent in an amount, by overall weight of the matte finish coating, of about 1.5% to about 10%.
4. The matte finish coating of claim 1 , wherein the coating substance comprises a clear-coat composition or a pigmented coating composition.
5. The matte finish coating of claim 1 , wherein the coating substance comprises a paint composition.
6. The matte finish coating of claim 1 , wherein the coating substance comprises an ink composition.
7. The matte finish coating of claim 1 , wherein the weight ratio of the micronized polymer matting agent to the optional silica matting agent is about 10:1 to about 1:10.
8. The matte finish coating of claim 7 , wherein a weight ratio of the micronized polymer matting agent to the silica matting agent is about 5:1 to about 1:5.
9. The matte finish coating of claim 8 , wherein a weight ratio of the micronized polymer matting agent to the silica matting agent is about 2:1 to about 1:2.
10. The matte finish coating of claim 1 , wherein an average particle diameter of the micronized polymer is from about 10 microns to about 25 microns.
11. The matte finish coating of claim 10 , wherein an average particle diameter of the micronized polymer is from about 14 microns to about 18 microns.
12. A substrate comprising the matte finish coating of claim 1 coated on at least one surface thereof.
13. The matte finish coating of claim 1 , wherein the silica matting agent comprises 0.5% to about 15% by weight of the matte finish coating composition.
14. A matte finish coating for application to a substrate, comprising of in a mixture:
a coating substance;
a non-emulsified micronized polymer matting agent consisting essentially of a micronized high-density polyethylene (HDPE) polymer or a micronized low-density polyethylene (LDPE) polymer wherein the HDPE or LDPE has an average particle diameter of about 6 microns to about 30 microns; and
wherein the matte finish coating comprises the micronized polymer matting agent in an amount, by overall weight of the matte finish coating, of about 0.5% to about 15%.
