Product Description Klüber Klüberalfa KRA 3-730

Klüberalfa KRA 3-730 is a lubricating fluid based on selected PFPE oils that was especially developed for automatic minimum-quantity spray lubrication of plug-in contacts. Klüberalfa KRA 3-730 reduces assembly forces and protects surfaces effectively against tribological ageing without increasing contact resistance. A newly developed additive package prevents wear due to vibration (fretting corrosion) or frequent plug cycles, thus considerably increasing the operativeness of the lubricated contacts. Klüberalfa KRA 3-730 contains fluorescent indicators which make automatic, visual quality controls easier.

Application notes

We recommend applying Klüberalfa KRA 3-730 by means of automatic spraying systems or immersion bath onto the clean contacts. A low-boiling, non-flammable solvent ensures quick drying. An average film thickness of approx. 2 µm is sufficient in most cases. Before applying Klüberalfa KRA 3-730 the contacts should be free of contamination and punching oil residues in order to ensure good wetting of the entire contact surface. For detailed information on spray application or film thicknesses, please seek consultation by one of our sales engineers. In general, Klüberalfa KRA 3-730 is compatible with plastics, however due to the great number of different plastics we recommend checking compatibility prior to series application.
