Metal Finishing

Phosphate Conversion Coatings

We offer Parkerizing, Bonderite, Parco-Lubrite and heavy, light, or calcium-modified phosphate coatings that improve paint or adhesive bonding, provide lubricity during installation, and act as a barrier coating to prevent break-in wear. In combination with various oils, phosphate coatings also promote corrosion resistance for protection during shipping, storage, and assembly.

Bulk handling (in barrels) or individual racking of parts is available to prevent damage to parts.

Torque-Tech

Our proprietary hybrid zinc phosphate coating that confers lubricity and corrosion resistance for high strength fastener installations requiring consistent torque, was developed for Cummins Engine, and provides the highly repeatable coating weight (± 50 mg/ft²) necessary for automated bolt installation in critical applications.  We maintain strict controls and offer custom recipes to provide the exact crystal structure that you need on each job, by using appropriate pre-treatment cycles and diligent testing of our tank solutions.

Passivating

When alloy steel surfaces are machined, embedded foreign particles should be removed by passivating. This treatment is recommended to clean the surface, to improve the corrosion resistance of stainless steels, and to prepare the workpiece for painting or lubricating.
