Precote®

Precote® Coating: Blockers, Self-Brakes and Thread Sealants

Safety and Reliability

Precote® coating is an advanced solution for locking and sealing threaded couplings. Thanks to its pre-assembled application, it eliminate the need for liquid sealants or additional mechanical devices, improving the efficiency of production processes and ensuring high reliability over time.

Features and Advantages of Coatings

Optimal locking and sealing for screws, bolts and threaded components
Pre-applied, ready-to-use application without the need for additional sealants
Resistance to vibrations, stress and liquid leakage
Easy identification thanks to specific coating coloring
Available in different formulations to suit specific industrial needs

Types of Precote® Coating

Precote® coatings are divided into four main categories, depending on the level of resistance required:

Strong clamp: prevents unlocking under high loads
Medium ascender: prevents unblocking caused by medium intensity loads
Braking: counteracts unscrewing due to light loads
Sealant: protects against liquid leaks, ensuring the tightness of the first screwing

Note: The brake treatment is usually applied with a stamp (from 90° to 120°), but if distributed over 360° it also ensures the tightness of the fluids at the first screwing.

Applications:

Thanks to its high versatility, Precote® coating is used in various industrial sectors, including:

Automotive industry: Clamping and sealing of components subject to vibration
Mechanical engineering: Improving safety in threaded connections
Industrial and machinery: protection against liquid leakage and corrosion
Electrical industry: Secure fastening of elements exposed to dynamic loads

Why choose Precote® coating?

Opting for Precote® coating means improving the reliability of threaded components, reducing maintenance costs and simplifying assembly processes. With a range of solutions to suit any industrial need, we ensure high performance and safety in every application.
