Parson Adhesives SONLOCK™ 3518 Anaerobic Gasket Sealant
Categories:	Polymer; Adhesive; Thermoset
Material Notes:	SONLOK 3518 is an anaerobic gasket sealant, which develops medium strength in a short time. The compound cures in the absence of air between close fitting metal surfaces. SONLOK 3518 is a flexible gasketing sealant, which will flex with minor flange movements. Provides resistance to low pressure immediately after assembly of flanges. Applications: Typically used as a form-in-place on rigid flanged connections, e.g. gearbox and engine casings, etc. Thixotropic nature reduces the migration of liquid product after application.
