Pre-coating Solution


What is Pre-coating ?

Pre-coating consists in applying on a cylindrical threaded or smooth component a special product which is activated when the part is assembled or press-fitted.

The products used are of different types:

– Micro-encapsulated locking products
– Sealing products
– Polyamide Patch
– Anti-seizing products


Advantages of Pre-coating are various:

Pre-coating products are applied in a liquid form via different processes: dipping, pouring or brushing. Once they have been applied, the coated parts are steamed to eliminate the solvent and to obtain a smooth and dry film.
The life shelf of the parts is between 1 and 4 years.
