Loctite AA 312 One-part Acrylic Adhesive 50ml

LOCTITE AA 312 (50ml) is a fast-fixturing amber/clear modified acrylic ester structural adhesive engineered for maximum efficacy in bonding close-fitting assemblies. This industrial-grade adhesive permanently joins components, preventing costly mechanical failures and joint alignment shifts caused by operational stresses. Whether you are securing rigid components or assembling close-tolerance joints, this premium structural bonding liquid provides a robust, highly reliable seal on all compatible materials—including difficult or dissimilar substrates.

Why Choose LOCTITE AA 312 Fast Fixturing Adhesive?

• Fast Fixturing: Specifically engineered for applications requiring rapid fixture times between close-fitting parts.
• Dissimilar Material Joining: Provides versatile, high-strength adhesion across a variety of contrasting materials.
• Low Viscosity Liquid: Features a 1,000 mPa.s (cP) Brookfield viscosity profile, ideal for deep penetration into tight gaps.
• Anaerobic Curing Option: Cures efficiently when confined in close-fitting gaps with the aid of a specialized activator.
• Controlled Application: Designed to prevent unneeded product migration when properly paired with its designated companion accelerator.

Technical Specifications

• Strength: High Structural Bond
• Color: Amber, Clear
• Container Size: 50ml
• Certifications: Henkel LMS Quality Specification (Dated November 4, 2002)

Simple Application Instructions

1. Clean: For optimal results, ensure all bond surfaces are completely clean and free from grease, oil, or previous contaminants.
2. Apply: To ensure a fast and reliable cure, apply Activator 736 or 734 to one of the bond surfaces and the liquid LOCTITE AA 312 adhesive to the other surface. For larger gaps (up to 0.125 mm) or maximum cure speed, apply the activator to both surfaces.
3. Assemble: For single-sided activation, assemble the parts within 15 minutes. If both sides are activated, assemble immediately within 1 minute. Keep the bond held or clamped firmly until the adhesive has fully fixtured. Allow 24 to 72 hours for full strength development.

Frequently Asked Questions (FAQ)

What is LOCTITE AA 312 used for?

LOCTITE AA 312 is a fast-fixturing structural adhesive designed for high-strength bonding applications. It is specifically formulated to prevent dissimilar rigid assemblies from separating or shifting when subjected to operational mechanical stress.

Can LOCTITE AA 312 be disassembled?

No, it is a permanent structural adhesive. Because it is highly resilient, removing excess uncured liquid requires an organic solvent wipe, while fully cured bonds generally require specialized mechanical removal methods or extreme chemical treatments to break down.

Does LOCTITE AA 312 work on Material/Surface?

Yes. LOCTITE AA 312 offers robust performance across a variety of hard surfaces. It is highly effective on rigid substrates like metals and glass, as well as ceramic surfaces. However, it is not normally recommended for use on plastics, particularly thermoplastics, where stress cracking could occur.

Is LOCTITE AA 312 safe for Specific Environment/Industry?

LOCTITE AA 312 is manufactured under strict Henkel LMS quality standards. However, it is not recommended for use in pure oxygen or oxygen-rich systems, and should never be selected as a sealant for chlorine, aqueous washing solutions that conflict with curing, or other strong oxidizing materials.
