SOAP GEL BASED GLUE STICK

摘要

Adhesive sticks are obtained using water-based preparations of synthetic polymers of adhesive character and soaps which act as shaping gel-forming components. Mixtures of polyurethanes and polyvinyl pyrrolidone are used as the synthetic polymers. The polyurethane may be in the form of a dispersion and produced by reacting at least one polyol, at least one polyfunctional isocyanate and a component capable of salt formation in alkaline aqueous solution and/or a nonionic hydrophilic modifying agent.
