Coating compositions and related products and methods
View Patent ↗A coating composition including an uncured binder component and a particle component. The particle component can include a plurality of first particles and/or a plurality of second particles. The first particles are non-spherical and have an average particle size in the range of from about 0.5 to about 20 μm and have a Mohs hardness in the range from about 4 to about 7. The first particles are made of material comprising inorganic, amorphous, glass material. The second particles are at least substantially spherical and have an average particle size in the range of from about 0.5 to about 70 μm. The second particles are made of material comprising organic material.
1. A coated sheet adapted for lamination to a substrate, said coated sheet comprising:
a) a paper, fabric or plastic sheet having a major surface bearing a printed pattern, and
b) overlaying said printed pattern, a coating composition that comprises:
1) a substantially cured polymeric binder, and
2) a plurality of particles that comprise,
(A) non-spherical inorganic, amorphous, glass particles, said glass particles having
(i) an average particle size of from 1 to 12 μm, and
(ii) a Mohs hardness of from about 4 to about 7, and
(B) substantially spherical organic particles having an average particle size of from 20 to 30 μm, wherein at least a portion of said organic particles provide the coated sheet with a non-uniform, discontinuous surface.
2. The article of claim 1 , wherein the substantially cured polymeric binder has a thickness of from 1.25 to 12.5 μm.
3. The article of claim 1 , wherein the glass particles comprise natural glass.
4. The article of claim 1 , wherein the glass particles are present in an amount of from 0.5 to 50% based on the total weight of said coating composition.
5. The article of claim 1 , wherein the organic particles are present in an amount of from 0.01 to 50% based on the total weight of said coating composition.
6. The article of claim 1 , wherein the surface of the coating composition opposite said printed pattern has a Sheffield Smoothness of from 100 to 350 cc/min.
7. The article of claim 1 , wherein the organic particles comprise an acrylic resin.
8. The article of claim 1 , wherein the organic particles comprise at least one a compound chosen from polymethyl methacrylate, polyacrylic ester, or polybutyl (meth)acrylate.
