    Abstract: Zinc crosslinked acrylic dispersions can initiate hardening of multicomponent polyurethane coatings based on polyester polyols or polyurethane polyols and decrease the coating tack-free time. Zinc carbonates and ultrafine zinc oxide can initiate hardening of multicomponent polyurethane coatings 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.

    Abstract translation: 锌交联的丙烯酸分散体可以引发基于聚酯多元醇或聚氨酯多元醇的多组分聚氨酯涂料的硬化,并降低涂层无粘性时间。 碳酸锌和超细氧化锌可以引发多组分聚氨酯涂层的硬化,并降低涂层的无粘性时间。 降低的无粘性时间有利于更早地应用额外的聚氨酯层,并且早期使涂层制品返回使用,并且可以提供改进的地板饰面。
