一般特征
Desmocoll 500/2 is a 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-flammable solvents, e.g. Methylene chloride. The bonds have outstanding resistance to the most commonly used PVC plasticisers.
