precote® 80

precote® 80 – High Strength Threadlocking for High Temperature Applications

precote® 80 is a high strength and high temperature resistant thread locking and sealing
coating designed to be used on all types of external or internal threaded fasteners. When it
comes to pre-applied threadlockers, there is none stronger than precote® 80.

When it comes to pre-applied adhesives, there’s none stronger than precote® 80. With its signature heat-resistant pink coating and exclusive dual micro-encapsulation design, it provides long-lasting, high-strength locking and sealing properties between male and female threads upon assembly.

The pre-applied precote® 80 forms a tack-free dried film, non-sticky and can be used in all kinds of assembly processes. Its fast-curing formula will cut time on the assembly line as well as provide excellent resistance to vibration, even under the most extreme operating conditions.

Also available with two additives:

3” , precote® 80-3 provides a fast curing time, accelerating the locking effectiveness.
“- 8”, precote® 80-8 is added for utilization with thread sizes M6 and smaller.

The following combinations are available:

precote® 80:
Standard thread locker for threads > M6 or pitches > 1mm.
precote® 80-3:
Accelerated curing for threads > M6 or pitches > 1mm. Yellow UV marker visible under UV light.
precote® 80-8:
Standard thread locker for threads ≤ M6 or pitches ≤ 1mm. White UV marker visible under UV light.
precote® 80-3-8:
Accelerated curing for threads ≤ M6 or pitches ≤ 1mm. White UV marker visible under UV light.


All versions of precote® 80 are high-strength thread locking coatings that retain their strength even at high temperatures. They can be used on all types of external or internal threads.
