Polyurethane coating cure enhancement using ultrafine zinc oxide
摘要:
Ultrafine zinc oxide can initiate hardening of 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.
