Solid Dry Film Non-Wettable Coating
For those applications where you want a coating that sheds oil, rather
than retains it — such as oil pans, windage trays, blower housings, and
valve covers — HPC has developed SDF-2
. A major component of this
coating is polytetrafluoroethylene (better known as DuPont’s Teflon). This
process works well in eliminating exfoliation/corrosion and oxidation on
zinc, aluminum, and magnesium. SDF-2 can be applied directly over more
conventional pretreatments such as anodizing, phosphating, and electroplating.
It is a black-pigmented coating with temperature stabilities from -100
degrees to +700 degrees.
