| Characterization: Aliphatic polyisocyanate prepolymer based on isophorone diisocyanate. As a binder for elastic coatings and surface sealing compounds. Properties / Applications: Desmodur® VP LS 2371 can be combined with latent hardeners such as Hardener® VP LS 2959 in the formulation of moisture-curing coatings. It can also be used with, for example, Hardener® DT and other special NH-functional co-reactants in the formulation of elastic coatings and surface sealing compounds for structural protection. On account of the polyether structure of this product, the resultant films are largely resistant to hydrolysis. However, if used outdoors, suitable light stabilizers must be added to counter the effects of sunlight. Information provided by Covestro |
