Loctite 675 Retaining Compound 50ml

Loctite 675 Retaining Compound is a high strength green methacrylate retaining compound engineered for maximum efficacy in joining cylindrical assemblies. This industrial-grade adhesive permanently bonds sleeves, wear rings, and bushings in place, preventing costly loosening and leakage caused by shock and vibration. Whether you are securing close fitting press fits or loose fitting slip fits, this premium anaerobic adhesive provides a robust, leak-proof seal on all ferrous or copper alloy metals—including steel.

Why Choose Loctite 675 Retaining Compound?

• High Strength Bond: Delivers a high shear strength of 20 N/mm² to ensure permanent cylindrical assemblies.
• Very Low Viscosity: Self-hardening liquid easily self-flows into minute spaces, making it ideal for close fitting press fits and joints with a maximum diametrical clearance of 0.1 mm.
• Slow Curing Formula: Provides a fixture time of 45 minutes on steel, allowing plenty of time for precise alignment and adjustment during assembly.
• Augments Mechanical Fits: Locks bearings on shafts and in housings, and seals mechanical fits that have small clearances.
• Thermal Stability: Maintains a reliable service temperature range of -55°C to +150°C (-65°F to +300°F).

Technical Specifications

Simple Application Instructions

1. Clean: For optimal performance, ensure all internal and external surfaces are clean and free of grease.
2. Apply: For slip fitted assemblies, apply adhesive around the pin and leading edge of the collar. For press fitted assemblies, coat the adhesive thoroughly onto the pin. Ensure the joint is completely filled.
3. Assemble: Assemble parts using a rotating motion for slip fits to ensure good coverage. For press fits, heat the collar sufficiently to create free clearance for assembly. Parts should not be disturbed until sufficient handling strength is achieved.

Frequently Asked Questions (FAQ)

What is Loctite 675 used for?

Loctite 675 is a high strength retaining compound designed primarily for joining cylindrical assemblies of all types. It is specifically formulated to lock bearings on shafts and in housings, bond pivot pins, adapters, or plugs, and prevent components from loosening or leaking due to vibrational stress.

Can Loctite 675 be disassembled?

No, it is a high-strength permanent adhesive. To disassemble, the components typically require localized heating to approximately 250°C to degrade the polymer matrix, followed by mechanical effort while hot.

Does Loctite 675 work on all surfaces?

It cures reliably when confined between ferrous or copper alloy metals. For other metals or thermoset plastics, the use of a primer like Locquic Primer T or N is required. It is not normally recommended for use on thermoplastic materials due to the risk of stress cracking.

Is Loctite 675 safe for oxygen or strong oxidizing systems?

No. This product is not recommended for use in pure oxygen and/or oxygen-rich systems, and it should not be selected as a sealant for chlorine or other strong oxidizing materials.
