Processes - Xylan Dry Film Lubricant

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 application of xylan to a substrate is very similar to the application of a Molybdenum Disulphide dry film lubricant (MoS2) DFL with discreet technical variations specific to each xylan coating type. In most cases the substrate needs to be thermally homogenised to a specified temperature i.e. 30ºC prior to spraying followed by a “flash off” typically in the range 100-150ºC to burn off the solvents in the xylan coating. This is then followed by further curing for at a substrate temperatures of 240ºC.
