Clear coatings acrylic coatings

Abstract

The presently disclosed and claimed inventive concept(s) relates generally to liquid-based coatings for writable-erasable surfaces, products that include such coatings, and methods for making and using the same.

What is claimed is: 
     
         1 . A coating product comprising a cured clear acrylic coating extending upon a substrate and having a surface, wherein the coating is formed from a base composition in a carrier optionally with a coating curing agent. 
     
     
         2 . The coating product of  claim 1 , wherein the coating is cured under ambient conditions. 
     
     
         3 . The coating product of  claim 1 , wherein after the surface is marked with a marking material, the marking material can be erased from the surface to be substantially invisible. 
     
     
         4 . The coating product of  claim 1 , wherein the base composition is produced by reacting a hydroxyl-containing acrylic resin, an alcohol, a silane compound, water, and an acid catalyst. 
     
     
         5 . The coating product of  claim 4 , wherein the hydroxyl-containing acrylic resin is produced by copolymerizing a hydroxyl-containing acrylic monomer with another ethylenically unsaturated group-containing monomer. 
     
     
         6 . The coating product of  claim 4 , wherein the alcohol is selected from the group consisting of methanol, ethanol, 2-propanol, butanol, isobutanol and combinations thereof. 
     
     
         7 . The coating product of  claim 4 , wherein the silane compound has a general chemical formula: R n Si(OR′) 4-n , wherein each R and R′ independently represent a hydrocarbon group, and n is 0≦n<4. 
     
     
         8 . The coating product of  claim 4 , wherein the acid catalyst is selected from the group consisting of hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and combinations thereof. 
     
     
         9 . The coating product of  claim 1 , wherein the carrier is a water-based solvent, a non-water based solvent or combinations thereof. 
     
     
         10 . The coating product of  claim 3 , wherein the marking material comprises a colorant and a solvent. 
     
     
         11 . A method of making a coating product, comprising the step of applying a coating to a substrate, wherein the coating is formed from a base composition in a carrier and a coating curing agent and curable under ambient conditions.
