Dav-Lon® is a chemically deposited nickel-phosphorous alloy that is specially treated, using our proprietary process, to infuse a fluorocarbon polymer into the electroless nickel matrix. This coating, which has a surface appearance similar to 300-series stainless steel, is used to further enhance the excellent lubricious wear and corrosion properties of Dav-Tech Plating's Dav-Lin® electroless nickel.

Benefits of Dav-Lon®

The ability to coat complex parts uniformly, allowing the deposit to mirror the substrate's surface contour, is Dav-Lon®'s greatest benefit. The coating deposits uniformly wherever it contacts your product, so we can process complex parts with no edge build up and ensure uniform coating thickness in recesses regardless of part configuration.

Typical Dav-Lon® Applications

Application Reasons for Use
Gun Components Wear, corrosion, appearance
Food Handling Equipment Wear, corrosion, cleanliness
Molds, Dyes Wear, corrosion, release, uniformity of deposit over complex shapes
Pumps Erosion, corrosion
Gears/Bearings Wear, contour replication
Hydraulic Cylinders Wear, corrosion, uniformity in IDs
Marine Electronic Parts Corrosion
Medical Corrosion, cleanliness
Printing (rolls, accessories) Wear, ink-resistance, uniformity
