Loctite 407 Prism Cyanoacrylate Instant Adhesive 50g

Loctite 407 Prism Cyanoacrylate Instant Adhesive 50g is a high-strength, ultra-clear instant adhesive engineered for maximum efficacy in bonding small to medium size parts. This industrial-grade adhesive permanently joins a wide variety of dissimilar materials, preventing costly component failures caused by mechanical stress or environmental factors. Whether you are securing close-fitting assemblies or intricate components, this premium cyanoacrylate adhesive provides a robust, leak-proof seal on all substrates—including difficult-to-bond plastics, rubbers, and polyolefins.

Why Choose Loctite 407 Instant Adhesive?

• Extremely Fast Curing: Achieves rapid fixture times when confined between close-fitting surfaces, minimizing downtime.
• Dissimilar Material Compatibility: Provides high-strength bonding across rubbers, plastics, metals, and polyolefins (when combined with Primer LOCTITE® SF 770 or LOCTITE® SF 7239).
• High Temperature Resistance: Formulated as a general-purpose adhesive suitable for applications where elevated heat resistance is required.
• Ideal for Small Bond Faces: Delivers exceptional bond strength even on very small, precise contact areas.
• Long Open Time & Low Viscosity: Low viscosity ensures clean, easy application with extended working time for precise part alignment.

Technical Specifications

• Product Type: Cyanoacrylate Instant Adhesive (Solvent-free)
• Strength: High strength on close-fitting bond faces
• Color: Clear / Ultra Clear
• Container Size: 50g
• Curing Type: Humidity / Atmospheric Moisture

Simple Application Instructions

1. Clean: For optimal performance, bond surfaces should be clean, dry, and completely free from grease.
2. Apply: Apply a small amount of the liquid adhesive to one surface. This product performs best in thin bond gaps (0.05 mm); increasing the bond gap will decrease the rate of cure.
3. Assemble: Assemble and tightly compress the parts immediately. The formula will begin curing rapidly once atmospheric moisture initiates the reaction between the close-fitting surfaces. Maintain full functional strength before exposing to heavy loads; full chemical and solvent resistance develops over at least 24 hours.

Frequently Asked Questions (FAQ)

What is Loctite 407 used for?

Loctite 407 is a low-viscosity, transparent instant adhesive designed for rapid bonding of small to medium parts. It is specifically formulated to securely join plastics, rubbers, and metals, preventing component loosening or separation due to high temperatures and operational stresses.

Can Loctite 407 be disassembled?

Yes, if required. Excess or bonded adhesive can be dissolved and removed using dedicated Loctite cleanup solvents, nitromethane, or acetone.

Does Loctite 407 work on difficult-to-bond materials?

Yes. Loctite 407 offers robust performance across standard plastics and rubbers. For notoriously difficult-to-bond polyolefin plastics and elastomeric substrates, it achieves high strength when used in combination with Primer LOCTITE® SF 770 or LOCTITE® SF 7239.

Is Loctite 407 safe for use in oxygen systems?

No. This product is not recommended for use in pure oxygen and/or oxygen-rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials. Always consult the Safety Data Sheet (SDS) for safe handling information.
