Pre-applied Strong and Medium Adhesives. These lock and seal any threaded connection, and can be applied to all types of metal and some plastics. During the screwing up and tightening of the threaded parts, the microcapsules break up and are distributed between the screw and the female screw along with the resins. When polymerisation is complete, the product reaches its full locking and sealant power, ensuring excellent levels of resistance to loosening, stresses and vibrations.
