PRESSURE WASHER OR STEAMER – use at 0.2 - 0.5 % at 150 ˚ F or higher. Apply for 30-90 seconds, alternating sides to prevent streaking.
SPRAY OR TUNNEL WASHERS – use Phos-Brite 251 to avoid foaming problems.
DIP TANK – use at 1 -10 % at 150 - 200 ˚ F. 5 - 30 minutes exposure time is required, depending on the type of metal and coating weight desired.
To store phosphated parts for extended periods (up to 5 years indoor), coat them in Phos-Brite 262.
Phos-Brite 252 is
a multi-metal iron phosphating compound designed for blackening of steel in
a hot dip tank. This product :
1. Cleans the metal of oil, grease and dirt.
2. Removes oxidation from the metal surface.
3. Conditions the surface for phosphate deposit.
4. Deposits a controlled amount of phosphate on the surface.
5. Protects treated parts from corrosion.
6. Provides a base for paint adhesion or lubricant retention.
Phos-Brite 252 incorporates superior surfactants and activators to produce smooth and uniform phosphate coating ( 50-150 milligrams per square foot ) in a one step process. When properly applied, the phosphate coating will have a black or grey colour on cold or hot rolled steel. This compound does not contain zinc or manganese and is completely non-hazardous and biodegradable.
