DuPont has developed a new water-based, low-VOC coating solution based on Teflon PTFE for fasteners in highly corrosive environments. This easy to handle one-coat system is particularly suitable for applications requiring very high corrosion resistance, dry lubrication and anti-seize properties to prevent galling.
>Results from a salt spray test according to ASTM B117 carried by an independent laboratory have confirmed that screws treated with this new coating solution have outstanding corrosion resistance even without surface pretreatment. Corrosion resistance can be still further improved by using suitable primers or substrate pretreatments.
