Loctite 415 Instant Adhesive 20g

Loctite 415 Instant Adhesive 20g is a high viscosity, ultra-clear methyl-based instant adhesive engineered for maximum efficacy in high-strength bonding. This industrial-grade adhesive permanently bonds small to medium-size parts, preventing costly assembly failures caused by operational vibrations or structural stresses. Whether you are securing precise components or heavy-duty joints, this premium instant adhesive provides a robust, clean seal on all key substrates—including metals, rubbers, and plastics.

Why Choose Loctite 415 Instant Adhesive?

• Rapid Fixture Time: *Cures very quickly (within 20 to 40 seconds) when confined between two tight-fitting surfaces.*
• Optimized for Metals: *Specially formulated for exceptional, high-strength adhesion to metal substrates, yielding a shear strength of 3600 psi on grit-blasted steel.*
• High Viscosity Formula: *The 1500 mPa.s thickness offers excellent control during application and makes it ideal for bridging small gaps up to 0.05 mm.*
• Polyolefin Compatible: *When combined with Loctite SF 770 or Loctite SF 7239 primers, it easily bonds difficult, low-surface-energy plastics and polyolefins.*
• Solvent-Free & Temperature Resilient: *Maintains a dependable bond within a clean, solvent-free composition across a temperature range of -65°F to 180°F.*

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external bonding surfaces to ensure they are completely free from grease, oil, and contaminants.
2. Apply: Apply a minimal amount of the high viscosity adhesive to one surface. This formula performs best in thin bond gaps around 0.05 mm.
3. Assemble: Align and press the parts together firmly. Hold for 20 to 40 seconds; the formula initiates its cure via ambient atmospheric moisture and achieves full chemical resistance within 24 hours. *Excess adhesive can be cleaned up using nitromethane or acetone.*

Frequently Asked Questions (FAQ)

What is Loctite 415 used for?

Loctite 415 is a high-strength instant adhesive designed primarily for general purpose bonding of small to medium-sized parts. It is specifically formulated to quickly secure metal assemblies, rubbers, and plastics against premature loosening or separation under mechanical stress.

Can Loctite 415 be disassembled?

Because Loctite 415 forms a highly rigid, permanent bond (especially on metals), disassembly can be difficult. Any excess uncured adhesive or bonded residues can be softened and dissolved using Loctite cleanup solvents, nitromethane, or acetone.

Does Loctite 415 work on plastics and difficult substrates?

Yes. Loctite 415 offers robust performance across standard plastics and rubbers. For difficult-to-bond polyolefin plastics, it achieves reliable adhesion when paired with a specialty primer like Loctite SF 770 or Loctite SF 7239.

Is Loctite 415 safe for oxygen-rich environments?

No. Loctite 415 is not recommended for use in pure oxygen or oxygen-rich systems, and it should never be selected as a sealant for chlorine or other strong oxidizing materials.
