Uv/eb curable biobased coating for flooring application

Abstract

A coating composition and a floor product are disclosed. The coating composition has a biobased component that includes urethane acrylate, vinyl ether, or polyester acrylate. The coating composition includes at least about 5% by weight of renewable and/or biobased component. The coating composition is radiation curable, formed by acrylating a biobased polyol acrylate, and reacting the biobased polyol acrylate with polyisocyanate to form a biobased resin. The floor product includes a cellulosic substrate and a biobased coating applied to the cellulosic substrate.

         7 . The coating of  claim 1 , wherein the biobased component includes diisocyanate or triisocyanate. 
     
     
         8 . The coating of  claim 1 , wherein the biobased component includes a biobased polyol acrylate. 
     
     
         9 . The coating of  claim 1 , wherein the coating includes at least about 30% by weight of renewable or biobased content. 
     
     
         10 . The coating of  claim 1 , wherein the coating includes at least about 40% by weight of renewable or biobased content. 
     
     
         11 . The coating of  claim 1 , wherein the initiator is a cationic type initiator. 
     
     
         12 . The coating of  claim 1 , wherein the coating qualifies for at least one point under the LEED rating system. 
     
     
         13 . The coating of  claim 1 , wherein the coating is a radiation curable coating. 
     
     
         14 . The coating of  claim 1 , wherein the coating is positioned on a flooring. 
     
     
         15 . The coating of  claim 14 , wherein the flooring includes a cellulosic substrate and the coating is positioned on the coating. 
     
     
         16 . A radiation curable flooring coating, comprising:
 a biobased component comprising renewable and/or biobased materials;   wherein the radiation curable flooring coating is formed by acrylating a biobased polyol acrylate; and   reacting the biobased polyol acrylate with diisocyanate or triisocyanate to form a biobased resin;   wherein the biobased resin is blended into a radiation curable biobased coating formulation including at least one initiator.   
     
     
         17 . The radiation curable flooring coating of  claim 16 , wherein the biobased polyol acrylate is directly blended into the radiation curable biobased coating formulation;
 wherein the radiation curable biobased coating formulation includes at least one initiator.   
     
     
         18 . The radiation curable flooring coating of  claim 16 , wherein the biobased polyol acrylate is directly blended into the radiation curable biobased coating formulation;
 wherein the radiation curable biobased coating formulation includes at least one epoxy resin or vinyl ether;   wherein the radiation curable biobased coating formulation includes at least one initiator.   
     
     
         19 . The radiation curable flooring coating of  claim 16 , wherein the initiator includes a cationic type photo initiator. 
     
     
         20 . A floor, comprising:
 a cellulosic substrate; and   a coating applied to the cellulosic substrate, the coating comprising a biobased component including urethane acrylate, vinyl ether, or polyester acrylate;   wherein the biobased component is blended with a coating formula, the coating formula including an initiator;   wherein the coating includes at least about 5% by weight of renewable or biobased content.
