Predominantly linear hydroxyl polyurethane. Desmocoll® 500/2 is a flexible polyurethane with an extremely high crystallization rate. It has outstanding adhesion on PVC substrates and particularly on rubber. Due to its excellent solubility, Desmocoll® 500/2 can used for adhesives, based on non inflammable solvents, e.g. Methylen chloride. The bonds have outstanding resistance to the most commonly used PVC plasticisers.
