Aqueous polyurethane coating system containing zinc crosslinked acrylic dispersion

摘要

Zinc crosslinked acrylic dispersions can initiate hardening of 2K polyurethane coatings based on polyester polyols or polyurethane polyols and decrease the coating tack-free time. The decreased tack-free times facilitate earlier application of additional polyurethane layers and earlier return of a coated article to service, and can provide improved floor finishes.
