Zinc Sealer
Zinc sealer is the process of coating zinc for protection against rust and corrosion. Zinc sealer is used as a final rinse over other chromate plating process. It has low viscosity and produces very thin coatings, making it suitable for both rack and barrel operations.
Zinc-Chro-SHIELD
Description
Zinc-Chro-SHIELD provides over 100 hours of salt spray protection over a hexavalent blue chromate to less than 5% corrosion.
Zinc-Chro-SHIELD provides over 600 hours of salt spray protection over a yellow hexavalent chromate to less than 5% corrosion.
Zinc-Chro-SHIELD provides over 350 hours of salt spray protection over high performance trivalent chromates to less than 5% corrosion.
Zinc-Chro-SHIELD is used as a final rinse, so there is no additional equipment required.
Zinc-Chro-SHIELD operates at room temperature to 140° F (60° C).
Zinc-Chro-SHIELD has very low viscosity and produces very thin coatings, making it suitable for both rack and barrel operations.
