Polymer bonding process

Abstract

The present application provides compositions, methods of making the compositions, methods of using the compositions, and kits having instructions for using the compositions for providing a bond between synthetic polymers or between a synthetic polymer and another type of substrate.

What is claimed is: 
     
         1 . A kit for producing a permanent bond between a synthetic polymer first surface and a substrate second surface, the kit comprising:
 a) a quantity of synthetic polymer preparation solution;   b) a quantity of a polymerization catalyst;   c) a quantity of surface insensitive cyanoacrylate structural adhesive; and   d) instructions to use the synthetic polymer preparation solution, a polymerization catalyst, and the surface insensitive cyanoacrylate structural adhesive to produce the permanent bond between the synthetic polymer first surface and the substrate second surface.   
     
     
         2 . The kit of  claim 1 , wherein the instructions comprise instructions to:
 a) apply the synthetic polymer preparation solution to the synthetic polymer first surface and, if the substrate second surface is a synthetic polymer, to the substrate second surface;   b) allow the applied synthetic polymer preparation solution to dry on each applied surface;   c) apply the polymerization catalyst to the synthetic polymer first surface;   d) allowing the applied polymerization catalyst to dry on the synthetic polymer first surface;   e) apply heat to warm the surfaces made of a synthetic polymer until surface temperatures reach between about 114°-120° Fahrenheit;   f) apply the surface insensitive cyanoacrylate structural adhesive to the second surface;   g) urge contact between the first surface and the second surface; and   h) apply heat to warm a seam formed between the first and second surface.   
     
     
         3 . The kit of  claim 2 , wherein the instructions to apply heat to warm the surfaces made of synthetic polymers comprise instructions to apply heat until the surface temperature reaches about 118° Fahrenheit. 
     
     
         4 . The kit of  claim 2 , wherein the instructions to urge contact between the first surface and the second surface comprises instructions to urge contact between the first surface and the second surface for approximately 15-20 seconds. 
     
     
         5 . The kit of  claim 2 , further comprising the instruction to i) allow the bond to cure for at least 7 days. 
     
     
         6 . The kit of  claim 2 , wherein the synthetic polymer preparation solution comprises quantities of hydrotreated light naphtha, isopropanol, and triethylenediamine. 
     
     
         7 . The kit of  claim 2 , wherein the polymerization catalyst is a cyanoacrylate accelerator composition which comprises an amine. 
     
     
         8 . The kit of  claim 7 , wherein the amine is a quantity of dimethyl toluidine (N,N-Dimethyl-p-toluidine). 
     
     
         9 . The kit of  claim 2 , wherein the surface insensitive cyanoacrylate structural adhesive comprises a quantity of cyanoacrylate ester.
