Xylan coating
Xylan coatings contain PTFE or other types of lubricants and are applied in thin films. Xylan Coatings provide lubrication and controlled friction, wear resistance, heat resistance, nonstick and release properties and, at the same time, can also protect from corrosion. Materials which can be coated with Xylan includes plastics, elastomers, glass, ceramics, fabrics, etc. Xylan coatings have a broad range of properties which make them ideal for a variety of applications. Xylan coatings applications include: automotive, aerospace, industrial, appliances, piping, impellers, non-stick applications, fasteners and electronics.
Since 1972, with the introduction of Fluoropolymer coating in America,
TEFCOTTM coated studs
bolts and nuts are widely used for enhanced corrosion resistance,
permanent thread lubrication and consistently low applied torque
to induced tension (clamping load).
Since then, almost all international petrochemical, oil drilling
rigs and chemical process industries have specified these studs
for both offshore and land based applications.
Apart from these TEFCOTTM coated
B7 stud, bolts are installed under sea splash zones and chemical
environments with great success

Properties:
Over a phosphate pretreatment, a TEFCOTTM system
far exceeds in performance when compared with galvanised, cadmium
plated,
aluminised or molycoated studs and other premium types of studs.
A
TEFCOTTM coating
prevents galling and reduces both 'make-up' and 'break-out' torques.

Typical Application:
The use of
TEFCOTTM coated
bolts is increasing in industrial applications, offshore, petrochemicals
and marine industries due to their property of
withstanding extreme corrosive environments and providing permanent
lubrication over a very wide temperature range.
