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.

What is claimed is: 
     
         1 . A radiation curable coating comprising a biobased polyol acrylate, the biobased component being blended with a coating formula, the coating formula including at least one initiator, wherein the biobased polyol acryate is derived from plant oil, and wherein the radiation curable biobased coating contains at least about 5% weight of renewable materials or biobased content. 
     
     
         2 . The radiation curable coating of  claim 1 , wherein the plant oil is directly acrylated to form the biobased polyol acrylate. 
     
     
         3 . The radiation curable coating of  claim 1 , wherein the plant oil is selected from the group consisting of castor oil, linseed oil, soy oil, tall oil, tung oil,  vernonia  oil,  lesquerella  oil, and cashew shell oil. 
     
     
         4 . The radiation curable coating of  claim 1 , wherein the radiation curable coating further comprises a diisocyante or triisocynate. 
     
     
         5 . The radiation curable coating of  claim 1 , wherein the initiator is a photoinitiator. 
     
     
         6 . The radiation curable coating of  claim 1 , wherein the biobased polyol acryate is further modified with a diisocyante or triisocynate. 
     
     
         7 . The radiation curable coating of  claim 1 , wherein the radiation curable coating includes at least about 30% by weight of renewable or biobased content. 
     
     
         8 . The radiation curable coating of  claim 1 , wherein the radiation curable coating includes at least about 40% by weight of renewable or biobased content. 
     
     
         9 . The radiation curable coating of  claim 1 , wherein the radiation curable coating is provided on a flooring. 
     
     
         10 . The radiation curable coating of  claim 9 , wherein the flooring is a flooring tile. 
     
     
         11 . A flooring product coated with a radiation curable coating, comprising:
 a substrate having the radiation curable coating provided thereon, wherein the radiation curable comprises a biobased polyol acrylate, the biobased component being blended with a coating formula, the coating formula including at least one initiator, wherein the biobased polyol acryate is derived from plant oil, and wherein the radiation curable biobased coating contains at least about 5% weight of renewable materials or biobased content.   
     
     
         12 . The flooring product of  claim 11 , wherein the plant oil is directly acrylated to form the biobased polyol acrylate. 
     
     
         13 . The flooring product of  claim 11 , wherein the plant oil is selected from the group consisting of castor oil, linseed oil, soy oil, tall oil, tung oil,  vernonia  oil,  lesquerella  oil, and cashew shell oil. 
     
     
         14 . The flooring product of  claim 11 , wherein the radiation curable coating further comprises a diisocyante or triisocynate. 
     
     
         15 . The flooring product of  claim 11 , wherein the initiator is a photoinitiator. 
     
     
         16 . The flooring product of  claim 11 , wherein the biobased polyol acryate is further modified with a diisocyante or triisocynate. 
     
     
         17 . The flooring product of  claim 11 , wherein the radiation curable coating includes at least about 30% by weight of renewable or biobased content. 
     
     
         18 . The flooring product of  claim 11 , wherein the radiation curable coating includes at least about 40% by weight of renewable or biobased content.
