KLUBERLECTRIC KR 44-102

Special grease for the lubrication of electrical switches, contacts and sensors.

Klüberlectric KR 44-102 is a special grease for the lubrication of electrical switches, contacts and sensors. It consists of a synthetic hydrocarbon oil and lithium soap incorporating a UV indicator for quality inspection. A special additive combination makes Klüberlectric KR 44-102 particularly suitable for the lubrication of electrical contacts. It is intended especially for the protection and lubrication of copper, tin and silver surfaces against corrosion. Further positive effects are: reduction of plug-in and switching forces, reduction of fretted oxide development, extended connecting and switching cycles, constantly low contact resistance and smoother switching transitions.

For electrical components in the automotive, industrial engineering and installations sector. Due to its specific base oil viscosity, Klüberlectric KR 44-102 works particularly well under low to medium contact forces and at low temperatures. It is compatible with most plastic materials and hence can be used for the lubrication of plastic/plastic material combinations. Klüberlectric KR 44-102 minimises contact resistance values under lifetime operating requirements subject to varying electrical and mechanical loads.
To utilise this special grease's full performance capacity, component parts to be greased should be cleaned to remove all foreign substances such as corrosion protection oils, waxes, etc. Electrical contacts should be bright and clean.
The lubricant can be applied by spatula, tampon printing or via automatic dosing equipment. Due to the many different material compositions, in terms of elastomers and plastics, compatibility with the selected materials should always be tested prior to series application.
