Klüber Klüberlectric R 64-401


Klüber Klüberlectric R 64-401 Is a paste for easy assembly of plastic and elastomer components in the electrical industry.


Benefits for your application


– Neutral especially towards silicone-based elastomers
– Low assembly forces
– Good electrical insulation
– Odourless also when heated




Klüberlectric R 64-401 is a fully synthetic assembly paste based on synthetic hydrocarbons and silicate.

Klüberlectric R 64-401 reduces the force needed to assemble silicone-based elastomers in electrical components and devices
without affecting the insulating effect of plastic and elastomer materials. Klüberlectric R 64-401 ensures these low forces for a considerably longer time than silicone-based assembly pastes; consequently, components can later be disassembled for inspection without being destroyed. The electroconductive characteristics of Klüberlectric R 64-401 are hardly affected by moisture.

Klüberlectric R 64-401 is neutral towards silicone-based elastomers. Due to the many different material compositions, we recommend component tests under real-life conditions for compatibility with the assembly paste prior to series application.
