Flame-resistant finish or coating

Abstract

A flame-resistant finish is adapted for a closure piece to form a detachable closure. The closure piece has a flat basic fabric (14) of warp threads (10), and weft threads (12). Functional elements (18) protrude on the front side of the basic fabric (14). The basic fabric (14) is provided with the flame-resistant finish. The fabric (14) and the functional elements (18) are predominantly, preferably entirely, made of flame-resistant plastic materials.

What is claimed: 
     
         1 . A flame-resistant finish for a flame-resistant closure piece that is adapted to a corresponding closure piece to form a detachable closure and that has at least one flat basic backing and functional elements protruding on a front side of the basic backing, the flame-resistant finish comprising:
 a solvent-free, moisture-curing, reactive polyurethane prepolymer-based melt adhesive.   
     
     
         2 . A flame-resistant finish according to  claim 1  wherein
 said melt adhesive additionally contains 10 to 90% polyester-polyol, 0 to 50% polyether-polyol, 5 to 35% polyisocyanate, 2 to 50% flame-retardant agents of at least one of antimony-free and halogen-free phosphorus compounds or triazine compounds, and additives of catalyst or a stabilizer as needed. 
 
     
     
         3 . A flame-resistant finish according to  claim 1  wherein
 said melt adhesive includes polyester-polyol therein. 
 
     
     
         4 . A flame-resistant finish according to  claim 1  wherein
 said melt adhesive includes polyether-polyol therein. 
 
     
     
         5 . A flame-resistant finish according to  claim 2  wherein
 said flame-retardant agents comprise antimony-free and halogen-free phosphorus compounds. 
 
     
     
         6 . A flame-resistant finish according to  claim 2  wherein
 said flame-retardant finish comprises triazine compounds.
