Precote® 85
High-Strength & Heat-Resistant Thread Coating with Controlled Torque / Tension
Precote® 85 are varnish-like, solvent free coating systems based on micro-encapsulated acrylates for sealing and locking of threaded parts. The dried film is tack-free, non-sticky and can be used in all kind of assembly procedures. Its characteristics as a locking and sealing element become effective only when the capsules are ruptured by shear and pressure stress and the adhesive is allowed to cure.
Advantages
- Curing begins in about 10 minutes with full locking in 8 hours
- Controlled friction to improve joint tension
- Epoxy chemistry for robust structural bonding performance
- High torque performance
- Environmental resistance to heat, automotive fluids, thermal and mechanical shock and vibrations
- Bonds to a broad range of fastener finishes
- Longest shelf life in the industry
- Complies with or exceeds major OEM specifications
- Seals against pressures up to 400 bar (5760psi)
- Parts are ready for assembly
- Precise thread coverage in every part
- Can be applied on external and internal threaded fasteners
- Is not affected by high humidity conditions
- Dry-to-touch and tack free with good adherence
Technical Data
- Color: turquoise (special colors available upon request)
- Thread Friction Value > 0.10 – 0.15
- Curing Time (RT) 8 hours (an additive of “-3” will reduce to 2 hours)
- Temperature Range: -50°C (-58°F) to +170°C (+338°F)
