LOCTITE® 5188
Features and Benefits
This highly flexible, form-in-place, anaerobic-curing gasketing sealant is designed for use on rigid metal flanged connections, particularly where there’s minor oil contamination of the flange surfaces. Works on aluminum substrates.
If you need a gasketing product but your flange surfaces have minor oil contamination, choose LOCTITE® 5188. This highly flexible, 1-part, anaerobic form-in-place sealant is designed for use on rigid metal flanged connections like gearboxes and engine casings, forms an instant seal, has excellent chemical resistance, and can be dispensed by hand or robotically with the appropriate LOCTITE® systems. Perfect for use on aluminum substrates where very good adhesion is achieved.
