Loctite 272 Acrylic Anaerobic Threadlocker Red 50ml

Loctite 272 Acrylic Anaerobic Threadlocker Red 50ml is a high-strength red threadlocking adhesive engineered for maximum efficacy in high-temperature locking and sealing. This industrial-grade adhesive permanently locks threaded fasteners, preventing costly loosening and leakage caused by intense vibration and thermal expansion. Whether you are securing studs, nuts, screws, bolts, or fittings, this premium anaerobic adhesive provides a robust, leak-proof seal on all metal fasteners—including stainless steel and brass.

Why Choose Loctite 272 High Temperature Resistance?

• Vibration Resistance: Prevents the loosening and leakage of critical threaded fasteners under heavy operational stress.
• Excellent Material Compatibility: Suitable for all metal fasteners, providing robust fixture times across steel (10 mins), brass (5 mins), and stainless steel (15 mins).
• Oil Tolerant Formula: Can tolerate slight contaminations of various industrial oils during application without losing bond strength.
• Seals Threads: Allows for through-hole tapping by completely sealing the thread engagement area.
• High Temperature Resilience: Specifically formulated to withstand extreme environments, performing reliably at temperatures up to 200°C (450°F).

Technical Specifications

• Product Type: Methacrylate-based Anaerobic Threadlocking Adhesive
• Strength: High
• Color: Red
• Container Size: 50ml

Simple Application Instructions

1. Clean: For optimal results, ensure all internal and external surfaces are clean, dry, and free of grease.
2. Apply: Apply the liquid adhesive to the bolt in a sufficient quantity to fill all engaged threads. This product performs best in thin bond gaps (0.05mm).
3. Assemble: Assemble and tighten the parts as required. The formula will begin curing once it is confined in the absence of air between close-fitting metal surfaces. Note: If the cure speed is too slow or gaps are too large, an activator (like Activator N or T) can be applied to the surfaces.

Frequently Asked Questions (FAQ)

What is Loctite 272 used for?

Loctite 272 is a high-strength anaerobic threadlocking material designed for heavy-duty assembly applications. It is specifically formulated to prevent high-temperature studs, nuts, screws, and fittings from loosening or leaking due to vibration and thermal stress.

Can Loctite 272 be disassembled?

Because Loctite 272 is a high-strength adhesive designed for permanent applications, disassembly using standard hand tools alone will be difficult. To break the bond without damaging components, you will typically need to apply localized heat (up to 200°C/450°F) to soften the cured polymer before unthreading.

Does Loctite 272 work on plastic?

No, Loctite 272 is not normally recommended for use on plastics, particularly thermoplastic materials, as it may cause stress cracking. It is explicitly engineered for metal substrates like steel, brass, and stainless steel.

Is Loctite 272 safe for oxygen systems?

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