Loctite 638 High-Strength Retaining Compound Green 50ml

Loctite 638 high-strength anaerobic retaining compound for slip-fit cylindrical assemblies (bearings, bushings, sleeves, gears on shafts). Green, 50 ml bottle. Used by maintenance technicians and installation crews across industrial, marine and construction service.

Dimethacrylate ester (urethane methacrylate), green; one-component anaerobic retaining compound that cures in the absence of air between close-fitting metal parts; oil-tolerant, high temperature resistance. Bonds cylindrical slip- and press-fit assemblies and prevents loosening and leakage from shock and vibration. Viscosity approx 2,750 mPa.s (Brookfield); compressive shear strength on steel pins/collars approx 25 N/mm2 per ISO 10123; maximum diametral gap fill 0.25 mm; fixture time on steel approx 4 min, full cure 24 h; operating temperature -55 to +180 degC; specific gravity approx 1.1. Henkel order no. 21448 / IDH 1835936, 50 ml bottle.
