Loctite 422 Instant Adhesive 50g

Loctite 422 Super Bonder Instant Adhesive 50g is a high viscosity, general purpose, clear ethyl-based instant adhesive engineered for maximum efficacy in bonding small to medium-size parts. This industrial-grade adhesive permanently binds surfaces together, preventing costly assembly failures caused by weak joint adhesion. Whether you are securing structural components or intricate assemblies, this premium cyanoacrylate provides a robust, seamless hold on all substrates—including difficult-to-bond plastics and rubbers when used with a compatible primer.

Why Choose Loctite 422?

• Rapid Fixture Speed: Achieves fixture strength in just 20 to 40 seconds, minimizing downtime and accelerating production lines.
• Versatile Substrate Bonding: Offers excellent adhesion across a wide variety of materials, making it highly effective for metals, rubbers, and plastics.
• Gap Filling Control: The high viscosity formulation (2500 mPa·s) prevents run-off and allows for controlled application on vertical or porous surfaces.
• Solvent-Free Formula: An eco-conscious, 100% reactive liquid compound that cures very quickly when confined between two closely fitting surfaces.
• Environmental Resilience: Designed to perform consistently across a wide operational temperature range of -65°F to 180°F.

Technical Specifications

Simple Application Instructions

1. Clean: For optimal performance, ensure all bond surfaces are completely clean and free from grease, oil, or contaminants.
2. Apply: Apply a thin layer of the liquid adhesive to one of the surfaces. This product performs best in thin bond gaps (0.05 mm).
3. Assemble: Bring the parts together immediately and press firmly. The formula initiates its curing process via atmospheric humidity and cures rapidly when confined between the two surfaces. Hold for 20–40 seconds until fixtured, and allow 24 hours for full chemical and solvent resistance to develop.

Frequently Asked Questions (FAQ)

What is Loctite 422 used for?

Loctite 422 is a general-purpose instant adhesive designed for the fast bonding of small to medium-sized parts. It is specifically formulated to create high-strength, permanent bonds on everyday industrial materials like metals, plastics, and rubbers to prevent components from shifting or detaching under mechanical stress.

Can Loctite 422 be disassembled?

Because it creates a permanent, high-strength bond, physical disassembly can be challenging without damaging substrates. However, excess or unwanted adhesive can be dissolved and removed using specialized Loctite cleanup solvents, nitromethane, or acetone.

Does Loctite 422 work on difficult plastics?

Yes. While it adheres beautifully to standard plastics and rubbers right out of the bottle, it can also be successfully used on challenging polyolefins when paired in combination with a primer such as LOCTITE® SF 770 or LOCTITE® SF 7239.

What are the storage requirements for Loctite 422?

To maximize shelf life, store the product in its unopened container in a cool, dry location. The optimal storage temperature is between 8°C and 21°C. Storage below 8°C or above 28°C can adversely affect the liquid adhesive's properties.
