PTFE coated studs, bolts and nuts
PTFE coated fastener’s provides exceptional corrosion resistance, low coefficient of friction, consistent tensioning and subsequent ease of installation and removal.
Extensive testing and field use have proven that the future of coated fastener’s lies with Fluoropolymer coatings. Previously hot dip, galvanized, cadium or zinc plated fastener’s were considered the standard. But these coatings could not stand up to the corrosive atmospheres prevalent in many industries. The most widely used application is on B7 studs with 2H nuts.
Dramatic improvements in efficiency, life expectancy and corrosion resistance are claimed to be imparted to Nut and Bolt connectors by the application of a low friction PTFE coating. PTFE coated connectors have out-performed all others in aggressive any noticeable effect.
Ptfe – Fluorocarbon Coating – Xylan 1070 / Xylan 1024 Blue / Red
Ceramic Filled Fluorocarbon Coating – Xylar 1 or Xylar 2 and Xylan 1070
PTFE coating on fasteners will have thickness range from 25± 5 microns to 45± 5 microns
Xylan® Coatings are a family of fluoropolymer coatings designed for use on various types of OEM components and fasteners to prevent corrosion and increase the life of the product. Most Xylan® coatings contain PTFE or other types of lubricants and are applied in thin films. Scroll down to see the Xylan® coatings we offer and their individual uses.
