Silane-Functional Polyurethane-Urea Binder
WorléePur Si (2K-Isocyanate free)
2-component silane-functional polyurethane-urea binder, moisture-curing, acid-catalyzed
The silane-functional polyurethane-urea binders of this WorléePur Si range cure isocyanate-free. As activator/2.component acid catalysts are added. Depending on the formulation, pot lives of more than 24 hours or even several weeks can be achieved. Due to the very fast drying times, the binders in this group are particularly suitable for industrial applications. Thanks to silane cross-linking, coatings on this basis can be cured and processed well even at very high humidity levels.

WorléePur Si (11component)
1-component silane-functional polyurethane-urea binder, oxidative and moisture-curing
The silane-functional polyurethane-urea binders in this WorléePur Si series achieve exceptional properties, particularly in terms of drying speed, hardness and chemical resistance. By combining oxidative drying and the reaction of the silane groups, the binders in this group enable significantly improved properties compared to conventional alkyd resins, even under more critical climatic conditions. The resistance of the coating systems is similar to that of conventional 2K isocyanate cross-linked coatings.
