Properties of silane-functional polyurethane-urea binders compared to classic two-component polyurethane coatings
Urethane has been the basis for high-quality two-component coatings for decades. The development of this technology changed the coatings industry permanently, and even today a wide variety of developments are taking place on this basis. The increasing reduction of solvent contents also requires an adaptation of the base binders used. These must have a higher solids content at the same viscosity level, which requires a reduction of the average molecular weight. Suitable catalysts still ensure acceptable drying times and good reactivity here, but significantly reduce the pot life or processing time.
Our moisture-curing polyurethane-urea binders make it possible to decouple drying and processing time. However, the technology also enables the optimisation of other properties of classic polyurethanes.
