Largely linear hydroxyl polyurethane. Desmomelt® VP KA 8702 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, economical and environmentally friendly 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).
