LOCTITE® 5800

Features and Benefits

A 1-part, red, medium-strength, thixotropic acrylic gasketing sealant for form-in-place gasketing on rigid flanged connections.
LOCTITE® 5800 is a 1-part, medium strength, dimethacrylate ester gasketing compound for sealing close-fitting joints between rigid metal faces and flanges: typically gearbox and engine casings. It fluoresces under UV light – great for quality control. This red viscous sealant provides resistance to low pressures immediately after assembly. Its thixotropic nature makes it easy to apply and reduces sealant migration after application. It cures at room temperature when confined in the absence of air between close-fitting surfaces. The product formulation caries no hazard symbols, risk or safety phrases.
