JJ 12AX7 / ECC83S V1

The product curing (polymerisation) is carried out under the exclusion of atmospheric oxygen (anaerobic) and the catalytic action of the metal (metal contact). The product is used to secure screws in the state as delivered, without cleaning. Fixates stud bolts, ball and antifriction bearings that typically do not have to be dismantled. Especially suited for highly stressed screw connections.
