Xylan gives 150 million cycles at elevated temperatures

Lubricating a rotor for an automotive air-conditioner blower presented a difficult problem.

The rotor was formed with powder metal, which meant baking to remove impregnants prior to cleaning and coating. Another problem: The unit operated in a refrigerant, which is detrimental to most coating resins.

A coating of Xylan sealed the vane slots in the rotor and reduced friction on the sliding vanes. Qualifying tests showed that the Xylan coating withstood 150 million cycles at 8,000 rpm, at temperatures up to 185°C/365°F, and provided a unique solution to enable the design to become a reality without compromise.

Xylan sealed the vane slots in the rotor,

reduced friction and increased wear life.
