Polyurea self-sealing target

Abstract

A polymer material is adapted to coat a weapons training target that has the ability to self-heal and maintain its useful life significantly longer than conventional targets. The polymer material includes a polyurea formed from a mixture of about 1 part isocyanate to about 1 part polyetheramine. Methods for making the targets include coating a target mold with the polyurea polymer coating.

What is claimed is: 
     
         1 . A self-sealing target comprising:
 a polyurea polymer coating formed from an isocyanate and a polyetheramine in a 1:1 volumetric ratio.   
     
     
         2 . The self-sealing target of  claim 1 , wherein the polyurea is formed from a 100 percent solids, two component polymer hybrid ceramic putty. 
     
     
         3 . The self-sealing target of  claim 1 , wherein the polyurea contains no volatile organic compounds. 
     
     
         4 . The self-sealing target of  claim 1 , wherein the target is a military training target. 
     
     
         5 . The self-sealing target of  claim 1 , wherein the polyurea polymer coating is disposed on the target with a thickness from about 1/16 inch to about 5/16 inch. 
     
     
         6 . A method for making a self-healing target, comprising:
 coating a target mold with a polyurea polymer coating formed from an isocyanate and a polyetheramine in a 1:1 volumetric ratio;   allowing the polyurea polymer coating to cure; and   removing the self-healing target from the mold for use.   
     
     
         7 . The method of  claim 6 , wherein the target withstands hundreds of bullet strikes without developing holes and falling apart. 
     
     
         8 . The method of  claim 6 , wherein the polyurea polymer coating is disposed on the target mold with a thickness from about 1/16 inch to about 5/16 inch. 
     
     
         9 . The method of  claim 6 , wherein the polyurea polymer coating is formed from a 100 percent solids, two component polymer hybrid ceramic putty. 
     
     
         10 . The method of  claim 6 , wherein the polyurea polymer coating contains no volatile organic compounds. 
     
     
         11 . The self-sealing target of  claim 6 , wherein the target is a military training target.
