Desmomelt® VP KA 8702

Desmomelt VP KA 8702 is a largely linear hydroxyl polyurethane. It is a hot melt adhesive powder produced by grinding flexible polyurethane granules with a very high rate of crystallization and very low thermoplasticity. A typical application for Desmomelt VP KA 8702 is the fast and economical production of laminated articles by means of scatter coating. Desmomelt VP KA 8702 allows the economic production of technical textiles as well as footwear and leather goods. Desmomelt VP KA 8702 has very good adhesion on textile substrates and on a large number of other materials (rubber, wood, polyurethane elastomers, aluminium foils and plastic films, e.g. ABS/PVC blends). It also has excellent adhesion on flexible PVC.
