Wider scope of application for gasketing adhesive

Wider scope of application for gasketing adhesiveLOCTITE gasketing adhesives already offer numerous advantages over conventional pre-cut compression gaskets but, thanks to the continuous development, the technology can now be used for even more applications. Henkel has just confirmed that its popular LOCTITE 518 gasket sealant can now cure through light surface contamination, provides greater application flexibility and improved curing on inactive metals without an activator.

Major causes of failure and leakage of a compression gasket are poor surface contact, propensity to relax under dynamic load and bolt hole distortion that causes it to crack, tear, rupture or extrude. By comparison, LOCTITE gasketing adhesives fill all voids, resist high pressure when fully cured on assembly and maintains clamp load.

The new oil-tolerant formula of LOCTITE 518 ensures a consistent cure in standard workshop and maintenance conditions. Its performance isn’t compromised by most common industrial surface contaminants and inactive flange substrates, e.g. stainless steel or aluminium. The product supports thinner, lightweight flange designs and its robust curing and durability provide better performance in harsh operating environments.

LOCTITE 518 is a medium-strength anaerobic gasketing adhesive designed for use on cast iron, cast aluminium and steel-flanged mating surfaces. It fills gaps of up to 0.25mm and forms a semi-flexible, chemical-resistant seal that will not tear or degrade. Parts are easily disassembled, even after extended service by simply applying a cleavage load between the flanges.
