Loctite High Strength Retaining Compound Liquid Bottle 10 ml, Urethane Methacrylate, Operating Temperature -55°C Loctite 638

Loctite Loctite 638 is a high strength retaining compound formulated as a green urethane methacrylate liquid. It is designed for the secure bonding of cylindrical components where bond gaps can be as large as 0.25 mm. The compound fills the inner spaces between parts to ensure 100% contact between mating metal surfaces, providing strong and precise assemblies.

This retaining compound works robustly on both active metals like mild steel and passive substrates such as stainless steel and plated surfaces. It cures anaerobically, forming a resilient bond that resists loosening, leakage, shock, and vibration, making it ideal for industrial applications.

The product tolerates minor contamination from oils including cutting fluids, lubrication, and anti-corrosion agents, ensuring reliable performance in harsh manufacturing environments. Its single-component nature simplifies application and reduces preparation time.

Loctite 638 is highly suitable for bonding shafts, gears, pulleys, locking bushes, and sleeves into housings and onto shafts, delivering excellent resistance to dynamic, axial, and radial loads. It enhances load transmission efficiency by eliminating micro-movements and reducing fretting corrosion, thereby extending component life.

Operating temperature ranges from -55°C to 150°C allow application in varied industrial environments. Packaged conveniently in a 10 ml bottle, it supports precise dosing and waste reduction.

Manufactured in Ireland, this product meets stringent quality standards. It does not carry specific certifications but maintains compliance with industry norms for performance. Ensures robust curing performance across various metal substrates.
