Klübertemp GR RT 15 N Long-term lubricating grease NSF 100g

Klübertemp GR RT N greases are white, homogeneous long-term greases based on perfluorinated polyether oils (PFPE) and polytetrafluoroethylene (PTFE). This series contains greases with a range of specific additives for use in different applications.

Klübertemp GR RT 15 N shows good compatibility with plastics and elastomers, enabling a wide range of component materials to be selected.

Benefits for your application:

• For use at high operating temperatures up to 250 °C
• For applications exposed to aggressive media

Application:
Klübertemp GR RT N greases are used in numerous sectors of industry and a wide variety of components operating at high temperatures.

Behaviour towards elastomers and plastics:
Lubricants based on perfluorinated polyether oils and polytetrafluoroethylene are generally regarded as neutral towards most elastomers and plastics  (exception: perfluorinated rubber).

Nevertheless we recommend testing compatibility with the material to be used, especially prior to series application.

Application notes:
For optimum lubrication results, we recommend cleaning the friction points with white spirit 180/210 followed by Klüberalfa XZ 3-1. Then blow the surfaces with clean, dry compressed air or hot air to remove solvent residues. For initial lubrication, the friction points must be clean and bright, i.e. free from oil, grease and perspiration. Klübertemp GR RT N greases are applied directly or by means of brush, spatula or lubricant dispenser.
The technical sales departments at Klüber Lubrication may be contacted at any time for advice to ensure optimum service life results.
