Loctite MR 5923 Aviation Gasket Sealant 16OZ Brush-Top Can

Loctite MR 5923 (known as Loctite 5923, Aviation Gasket Sealant) is a slow-drying, solvent-based liquid that seals close-fitting parts, machined surfaces and threaded connections. It dries to a pliable, tacky, semi-flexible film through solvent evaporation, so it works as a non-hardening gasket dressing on solid gaskets and on close-tolerance flanges. Typical uses include solid gasket dressing, machined faces, threaded connections, and aviation or engine assemblies where joints must stay serviceable.

Technology solvent based; chemical type modified resin, fillers and alcohol. Brown liquid, flow similar to SAE 10 motor oil; Brookfield RV viscosity (spindle 3, 5 rpm, 25 degC) 8,000 to 10,000 mPa.s (cP). Specific gravity 1.1 @ 25 degC. Cure by air dry (solvent evaporation) to a hard, semi-flexible film; assembly operational after approximately 4 hours, full cure after approximately 24 hours (dry time varies with temperature, humidity and gap). Operating range -54 degC to +204 degC. Retains effective sealing in contact with water, ethylene glycol, gasoline, motor oil and transmission fluid. Not for pure-oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidisers. Removable from metal with isopropyl alcohol. PDF file (TDS) attached. 16 fl oz brush-top can.
