Loctite 660 retaining compound(tube)

Why Choose Loctite 660 Over Other Retaining Compounds.

Most retaining compounds are designed for close-tolerance fits. Loctite 660 is different. Its urethane methacrylate formulation comes as a metallic gray paste with an exceptionally high viscosity ranging from 1,000,000 to 2,000,000 cP at 0.5 rpm which means it stays exactly where you put it and fills gaps up to 0.50 mm. That's twice the gap tolerance of many standard retaining adhesives. This makes it ideal for worn shaft restoration, where surfaces have been damaged by wear or corrosion and the tolerance is no longer tight enough for conventional products. Engineers in pump, motor, and compressor maintenance regularly turn to Loctite 660 precisely because it bridges the gap between a worn housing and its mating component without requiring expensive machining. The product is anaerobic and single-component, curing in the absence of air between metal surfaces. No mixing, no mess, and no complicated prep just clean the surfaces, apply, and assemble.

Strength and Performance Data

After a full 24-hour cure at room temperature, Loctite 660 achieves a steel shear strength of ≥17.2 N/mm² putting it firmly in the high strength retaining compound category. Elongation is under 2%, which means the cured adhesive is rigid and load-bearing, contributing to the structural integrity of the repaired assembly .The coefficient of thermal expansion (CTE) is 80×10⁻⁶ K⁻¹, matching common metal substrates closely enough to minimize thermal stress over repeated heating and cooling cycles. Loctite 660 also carries NSF Category P1 certification, making it suitable for use in food and beverage processing environments where incidental contact with food must be prevented. Storage should be maintained between 8°C and 21°C to preserve performance over the product's shelf life.
