ZINC

ZINC

• Zinc is an auxiliary drier, used in conjunction with redox metals. The primary function of the Zinc is to keep the film "open" by retarding surface drying, thereby permitting hardening throughout and preventing surface wrinkling. Zinc is also a powerful wetting and dispersing agent and when incorporated early in the formulation, greatly reduces the time of mixing and grinding. Extremely low color of Zinc facilitates addition without discoloration of film. Zinc is available as a solution in MTO in various concentrations.
