The preliminary coatings used in bonding contain micro- encapsulated, adhesive components in the coating to be applied. After drying, a non-sticky, dry film with product- specific coloration is then formed, which is immediately ready to use. The screw threads thus threated, develops the required protection and sealing characteristics after the pre-applied screw is screwed into the nut or specific component.
A differentiation is made between reactive and non- reactive adhesives.
Reactive adhesives (precote® 30, 80, 85, Scotchgrip 3M®) consist of 2 components. Acrylate and epoxy base for threadlocking and sealing.
Non-reactive adhesives (precote® 4, 5, 6, 9, 10-1, 19-2) are on an acrylate and polyamide base for threadlocking and sealing, too.
