Loctite 572 Thread Sealant

LOCTITE 572 is a white to off-white, medium-strength thread sealant. The product is designed for the locking and sealing of metal pipes and fittings. It is especially suited for use on coarse threads. It prevents loosening and leakage due to shock and vibration.

LOCTITE 572 is a methacrylate-based sealant. It cures at room temperature when confined between close-fitting metal surfaces. The curing process occurs in the absence of air. Viscosity of the product decreases under stress. This property reduces the migration of liquid product after application.

• Medium strength
• High viscosity
• Suitable for thread sizes up to M80
• Offers breakaway torque of 7 Nm
• Thixotropic to reduce adhesive migration

How to use Loctite 572:

1. For best results, clean all surfaces with a LOCTITE solvent. Allow it to dry.
2. If using on inactive metal or curing speed is too slow, use an activator spray such as LOCTITE SF 7471 or SF 7649. Allow it to dry.
3. Apply a 360° bead of LOCTITE 572 to the leading threads of the male fitting. Leave the first thread free. For bigger threads: adjust product amount accordingly. Apply a 360° bead of product on the female threads also.
4. Assemble and tighten as required.
5. Assemblies will seal instantly to moderate pressures. For maximum strength and solvent resistance, allow the product to cure for 24 hours, minimum.

Storage

Store LOCTITE 572 in the unopened container in a dry location. Optimal Storage: 8° C to 21° C. Storage below 8° C or greater than 28° C can adversely affect product properties.
