– under vacuum
Klüberalfa GR ZLHT is a white long-term grease based on perfluorinated polyether (PFPE) oil and a polytetrafluoroethylene (PTFE) thickener. The extremely high viscosity index, i.e. the very flat viscosity curve of the base oil, allows excellent sliding friction properties across a wide service temperature range.
Klüberalfa GR ZLHT is preferably used for the lubrication of plastics and seals where it shows exceptionally low friction values and a low tendency to stick-slip. This leads, for example, to a lower frictional heating of elastomers subject to dynamic loads and hence longer component life.
General behaviour towards elastomers and plastics:
Lubricants based on perfluorinated polyether oils and polytetrafluoroethylene are generally regarded as neutral towards most elastomers and plastics (possible exception: highly fluorinated rubber). Nevertheless, compatibility with the materials should be tested, especially prior to series application.
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. Klüberalfa GR ZLHT is applied directly or by means of brush, spatula or lubricant dispenser.
