Loctite 411 Prism Instant Adhesive 20g

Loctite 411 Prism Instant Adhesive 20g is a high-viscosity, clear instant adhesive engineered for maximum efficacy in high-strength bonding. This industrial-grade adhesive permanently bonds components, preventing costly structural failures and joint separation caused by shock, vibration, or high stress. Whether you are securing structural parts or filling small gaps, this premium ethyl cyanoacrylate adhesive gel provides a robust, leak-proof seal on all key substrates—including rubbers, plastics, and metals.

Why Choose Loctite 411?

• Excellent Peel Strength: Exhibits superior resistance to peeling and impact forces, ensuring long-term bond integrity.
• High-Viscosity Gel Formula: The thick, general-purpose gel consistency provides excellent gap-filling capabilities and prevents messy run-off during application.
• Enhanced Heat Resistance: Specially formulated with added-heat resistance to maintain structural bonds in demanding environments.
• Versatile Material Compatibility: Specially engineered to create high-strength bonds across a diverse mix of rubbers, plastics, and metals.
• Rapid Fixture Time: Achieves initial fixture in mere seconds, allowing for quick assembly before continuing to full cure.

Technical Specifications

• Product Type: Ethyl Cyanoacrylate Gel Adhesive
• Strength: High (3,200 psi Shear Strength on Grit Blasted Steel)
• Color: Water white to slightly cloudy / Clear
• Container Size: 20g
• Viscosity: 5,000 mPa.s (cP) Brookfield

Simple Application Instructions

1. Clean: For optimal results, ensure all bond surfaces are completely clean and free from grease. Excess adhesive or old residues can be dissolved with Loctite cleanup solvents, nitromethane, or acetone.
2. Apply: Apply the adhesive sparingly to one surface. This product performs best in thin bond gaps around 0.05 mm (increasing the bond gap will decrease the rate of cure).
3. Assemble: Align and press the parts together firmly. Fixture occurs in seconds. Atmospheric moisture initiates the curing process, and full chemical/solvent resistance is achieved after a full 24-hour cure at normal room humidity.

Frequently Asked Questions (FAQ)

What is Loctite 411 used for?

Loctite 411 is a general-purpose, high-viscosity instant adhesive designed primarily for structural bonding and gap filling. It is specifically formulated to prevent parts from loosening or separating when subjected to heavy mechanical stress, shock, or high-vibration conditions.

Can Loctite 411 be disassembled?

Disassembly can be challenging due to its high shear and peel strength. However, cured adhesive bonds can be softened or dissolved by applying specialized Loctite cleanup solvents, nitromethane, or acetone directly to the bond line.

Does Loctite 411 work on all materials?

Yes, Loctite 411 offers robust performance across a broad spectrum of industrial materials. It is highly effective on common metals, rigid plastics, and flexible rubber substrates alike.

Is Loctite 411 safe for all systems?

While safe for general industrial manufacturing, this product is not recommended for use in pure oxygen and/or oxygen-rich systems. It should never be selected as a sealant for chlorine or other strong oxidizing materials. Always consult the Safety Data Sheet (SDS) for comprehensive safe handling instructions.
