Loctite 496 Instant Adhesive

Loctite 496 Instant Adhesive (20g) is a low-viscosity, clear, general-purpose methyl cyanoacrylate instant adhesive engineered for maximum efficacy in high-performance bonding. This industrial-grade adhesive permanently bonds components, preventing costly structural failures and downtime caused by vibration, shock, or mechanical stress. Whether you are securing intricate electronics or heavy-duty machinery parts, this premium instant adhesive provides a robust, clear seal on all substrates—including difficult-to-bond plastics and rubbers.

Why Choose Loctite 496?

• Rapid Fixture Time: Achieves full fixture in just 10 to 30 seconds, maximizing assembly line throughput and efficiency.
• Metal-Bonding Specialist: Formulated with a methyl base specifically optimized to deliver exceptionally high shear strength on grit-blasted steel and other metal surfaces.
• Substrate Versatility: Provides strong adhesion across plastics, rubbers, and polyolefins (when used in combination with Loctite SF 770 or SF 7239 primers).
• Low Viscosity: Water-thin liquid (125 mPa.s) wicks effortlessly into close-fitting parts for a seamless, ultra-clear bond line.
• Reliable Thermal Stability: Maintains mechanical integrity and performance across a service temperature range of -65°F to 180°F.

Technical Specifications

• Product Type: Cyanoacrylate Instant Adhesive (Methyl-based)
• Strength: High (3,600 psi shear strength on grit-blasted steel)
• Color: Clear / Ultra Clear

Simple Application Instructions

1. Clean: For optimal results, clean all mating surfaces with a suitable Loctite cleaning solvent to remove oil, grease, and contaminants, then let dry completely.
2. Apply: Apply a thin layer of the liquid adhesive to one of the bond surfaces. Do not spread the liquid with a brush or tissue.
3. Assemble: Align and press the parts together immediately. Hold firmly or clamp for 10 to 30 seconds until the fixture takes hold. The formula cures rapidly by reacting with ambient atmospheric moisture.

Frequently Asked Questions (FAQ)

What is Loctite 496 used for?

Loctite 496 is a general-purpose instant adhesive designed primarily for bonding metals. It is specifically formulated to prevent component misalignment or bond failure due to fast assembly needs, and it is also highly effective on rubbers and plastics.

Can Loctite 496 be disassembled?

Disassembly can be challenging due to the high-strength plastic matrix formed upon curing. Bonds can typically be dismantled or cleaned using nitromethane or acetone solvents, or by applying sustained high temperatures above its operating limit to degrade the polymer matrix.

Does Loctite 496 work on polyolefins?

Yes. While polyolefins and difficult plastics are normally resistant to instant glues, Loctite 496 offers robust performance on these materials when paired with a surface primer such as Loctite SF 770 or SF 7239.

How should Loctite 496 be stored?

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