Phosphating of metals

The Phosfast products produce a conversion coating that can replace existing iron or zinc spray, soak phosphate lines on steel, aluminium, zinc substrate or allochrome. The application is a pretreatment for any painted surface in use in the automotive industry through industrial to household goods.

• Single stage cleaning and phosphate: the natural materials which make up the proprietory formulation act as a powerful cleaning agent, thus eliminating the cleaning station.
  
• Increased throughput: the proces takes between 45 seconds and 3 minutes depending upon temperature and coating weight required. The cleaning stage is eliminated.
  
• Reduces energy requirement: the coating is applied by spray or soak at operating temperature between 30 °C and 60 °C. Low incident of flash rusting allows drying ovens to be set at lower temperatures.
  
• Enhanced performance: natural accelerators and grain refiners react with the steel, aluminium or zinc surface and produces a strongly adhering amorphous polymer coating giving enhanced salt spray.
  
• Reduced effluent and waste: 80 higher process efficiency mean low sludging, long bath life > 3 years. Biodegradable ingredients means reduces BOD and COD.
  
• Safe: the natural ingredients are safe for users and environment. No impact on aquatic life or adverse bio-accumulative effects. Eliminating effluent treatment costs.
