Houston Plating & Coatings (HP&C, South Houston, Texas) has added low-weight phosphate to its list of plating and coating services.  Its new coating line provides low weight (150-500-mg/ft2) micro-crystalline zinc phosphate, says the company. The line’s low-weight phosphate tank is 30" wide x 142" long x 42" deep, with a lifting crane capacity of 4,000 pounds.

The phosphating process is a chemical reaction that occurs on an iron base substrate when the part is immersed in the phosphate solution. The primary benefits from phosphate coating are strong adhesion and corrosion protection. There are very few environmental issues related to the use of phosphate coatings.

“Phosphate conversion coatings are used on ferrous parts for corrosion resistance, lubrication, or as a foundation for subsequent rust preventatives, coatings or painting,” explains Eric Turner, HP&C’s COO and director of quality assurance. “Applied by immersion, the phosphate solution reacts with the surface of the part to form a thin gray layer of micro-crystalline zinc that is aesthetically pleasing and typically does not affect dimensional tolerances.”


  • Measuring the Surface Area of Fasteners

    How do you measure the surface area of a threaded fastener? How much coating would you put on it? How thick of a coating? What about non-threaded fasteners? The U.S. Department of Agriculture’s Forest Service, of all people, may have come up with the solution for those pondering how to coat sometimes-difficult small pieces using computer imaging and software to compute the area.

  • Waterborne painting process is a first at South Carolina BMW plant

    PPG launched the first use of waterborne compact paint technology in a U.S. automotive manufacturing plant at the BMW assembly plant in Spartanburg, S.C. This painting process has turned out to be a 2012 award winner and has opened up a new way for auto manufacturers to go leaner and become more efficient in their operations.
