Locking by bonding function
The assemblies unscrew because of the vibrations, shocks and thermic dilatations. Numerous technologies have been developed in order to secure the screwed assemblies to avoid untimely unscrewing.
The most efficient solution against unscrewing is to bond the threads by the pre-coat technology.
The technique consists in pre-coating the threads with a microencapsulated adhesive which is activated only while screwing. Upon assembly, the adhesive components are released and creates a bond between the male and female threads. It is the most effective anti-unscrewing solution.
Advantages
The pre-coated fasteners replace the common thread locking solutions thanks to utmost technical performances and economical advantages:
Excellent performances: excellent resistance against vibrations
Easy conception: replaces standard screws without a re-conception of the assembly
Rapid assembly: no need of a washer nor adhesive
Technical control: the deposed volume of the pre-coating product on the assembly is always the same
Excellent quality: no omission possible of the coating process
Important reduction of the assembly costs: high productivity in workshop and on construction site
Suppression of the hygienic and security problems due to the fluid adhesives
CHARACTERISTICS AND PRODUCTS
The pre-coating products that we apply come from long partnerships with many manufacturers.
