Paint Grip is pre-treated at the mill for subsequent painting in the as-received condition. The sheet goes through a phosphatizing process which produces a deposit of hydrated zinc on the galvanized surface, obtaining a dull gray appearance. This coating provides a good adherent base for painting, and also extends the life of the painted surface. Paint Grip is intended to be painted and the unfinished surface may weather unevenly.*
This process consists in a layer of zinc on each side of the steel sheet that is tightly adhering to the steel through the formation of an iron-zinc alloy bonding layer that is formed by a diffusion process while the heated steel strip is in contact with the molten zinc.
In a continuous, controlled process, coils of galvanized steel are first thoroughly cleaned and rinsed. A conditioning agent is then applied to promote the formation of a fine crystalline zinc phosphate coating. This process then converts the bare galvanized surface to an inert, crystalline zinc phosphate which is subsequently rinsed and sealed with a thin in-place chromate conversion coating. This entire process creates what is called a Bonderized finish.
A long-time favorite of the rainwater goods industry, zinc phosphate provides the perfect surface for field painting of flashing, gutters, downspouts, and other roofing materials, as well as signs and even enamel-coated interior fixtures.
