Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluroethylene that has numerous applications.
Xylan is a dry film lubricant (DFL) that acts the same way as Teflon and is used for its non stick properties also reducing friction, prevent scoring and galling enhancing corrosion resistance and providing secondary lubrication in the event of failure of the primary (conventional) lubricant. Xylan is available in many different grades and colours to various metal substrates please refer to attached PDFs. Currently we are concentrating on the application of 1000 series offering the 1010, 1014, 1052 and 1070 Xylan grades.
The substrate needs to be thermally homogenised to a specified temperature of 30ºC prior to spraying, followed by curing, typically in the range 100-150ºC, to burn off the solvents in the Xylan coating. This is then followed by further curing at temperatures in the range of 240ºC.
New Datasheets: Xylan and Molybdenum di-Sulphide
Xylan®, based upon the Whitford Xylan® family of coatings, are first and foremost dry film lubricants (DFL); however, they have many desirable secondary properties. These lubricants are combined in a matrix with the newest high temperature organic polymers resulting in ‘polymeric alloys’ formulated to provide unique and desirable properties.

Molybdenum di-Sulphide [MoS2] is one of the most lubricious coatings currently available. It has a dynamic coefficient of 0.01 and provides an exceptionally low slip surface, which can be used over a wide range of temperatures from cryogenic levels up to 400°C (fully run-in). MoS2 has the unique ability to lubricate precision components used within an extensive industrial sector spectrum. Read the full data sheet here.
