ABSTRACT:
A urethane prepolymer repair system is provided by an isocyanate-terminated polytetramethylene ether glycol prepolymer of about 3,500-10,500 molecular weight that cures to an elastomer upon exposure to atmospheric moisture and is packaged in a container capable of repeatedly dispensing the prepolymer with minimal exposure to ambient air, such as a collapsible tube or caulking gun cartridge. The repair system is used to build up worn down soles and heels of footwear, repair separations of soles and heels from shoe tops, and hundreds of other uses.
