The Zinc-Chro-SHIELD™ Yellow sealer is specially formulated to maintain the bright yellow color of yellow hexavalent chromated zinc deposits, while enhancing corrosion protection.  The sealer is said to provide more than 250 hours of salt spray protection over a hexavalent yellow chromate to less than 5% white corrosion.  The low viscosity and operating temperature make it an ideal final rinse in both rack and barrel operations, and it requires no additional equipment.
