A new DuPont™ Teflon® industrial coating that is the first truly water-based, low-VOC and easy-to-use coating with a corrosion resistance of up to 3,000 salt spray hours has been released by Intech Services. Specifically engineered for coating offshore, chemical processing and water treatment fasteners, the new coating is targeted towards applications requiring outstanding corrosion resistance, anti‐galling and dry lubrication.
Salt spray test results performed by an outside company show excellent corrosion resistance even without surface pretreatment, though the corrosion resistance can be enhanced if used with recommended primers and substrate pretreatments. Fasteners with a zinc base coat of .3 mils easily passed ASTM testing of less than 10% red rust at 3,000 salt spray hours. Excellent corrosion resistance can also be achieved without pretreatments on aluminum steel and stainless steel substrates. This one-coat product dwarfs the corrosion resistance of the current one-coat technology.
The water-based coating can be applied to thicknesses of 1-4.5 mils. Curing temperatures of 450 °F improve the process with less bake time and energy required. Coatings are available in colors including blue (857G-018) and red (857G-508), with yellow and black colors being added in the near future.
