<h2>Anaerobic adhesives (threadlocking and sealing)</h2> <p>Anaerobic adhesives are single-component industrial adhesives that cure only in the absence of air and when confined between metal surfaces【8†L7-L14】. They are widely used to lock threaded fasteners, retain bearings, and seal flanges. The adhesive remains liquid until applied to mating metal parts and the oxygen is displaced. Upon tightening the assembly, the lack of air triggers polymerization, creating a solid, 100% contact bond【8†L7-L14】.</p> <h2>Main Advantages</h2> <ul> <li><strong>Vibration resistance:</strong> Prevents fasteners from loosening under vibration【14†L528-L532】.</li> <li><strong>Chemical resistance:</strong> Resistant to oils, fuels and solvents【15†L53-L54】.</li> <li><strong>Corrosion protection:</strong> Seals and protects metal joints from corrosion.</li> <li><strong>Fast cure without air:</strong> Quick polymerization accelerates assembly.</li> <li><strong>Wide temperature range:</strong> Operates from –55°C up to +150°C (some grades up to +180°C)【14†L538-L540】.</li> <li><strong>Flexible formulations:</strong> Available in removable and permanent strengths for different applications.</li> </ul> <h2>Applications</h2> <ul> <li>Threadlocking of bolts and screws in automotive, machinery and equipment</li> <li>Bearing retention (shafts, bushings, pulleys)</li> <li>Flange and pipe sealing (gaskets, fittings)</li> <li>Hydraulic and pneumatic assembly sealing</li> <li>General industrial maintenance and assembly</li> </ul> <h2>How to Use</h2> <p>Ensure surfaces are clean, dry and oil-free. Apply the adhesive to threads or mating surfaces, assemble the parts, and tighten. The adhesive cures as air is displaced from the joint【8†L7-L14】. Use an activator or primer for difficult surfaces or large gaps to achieve a faster cure.</p>
