Lockfast G18 Gasket Maker


Lockfast G18 Gasket Maker is a red, fast cure, semi flexible, general purpose gasket maker. It is designed for sealing close-fitting joints between flanges and fixed metal faces and will flex with minor movement from the flange.  Cures when confined in the absence of air between close-fitting metal surfaces.  The product provides resistance to low pressures immediately after assembly.

Ideally used as a form-in-place gasket maker for applications on rigid, flanged connections, along with a great contamination tolerance, ideal for usage on cast iron, steel and aluminium. Good gap cure making it useful in engine casings and gearboxes applications.


Directions For Use


1. For optimum performance surfaces should be clean and free of grease.

2. If the material is an inactive metal consider using activator.

3. Shake the product thoroughly before use. Apply several drops to parts to be sealed.

4. Assemble as required.

5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.


Fixture Time vs. Substrate


There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.

For more information on strength of bond and cure time, please see the Lockfast gasketing and pipe sealants technical information sheet.


Disassembly and Clean-up


Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
