Henkel has developed a new innovative formulation for Loctite 518 Gasket Sealant that cures through light surface contamination, provides greater flexibility and adhesion as well as improved curing on inactive metals without a primer.
Loctite gasket sealants offer a reliable alternative to conventional compression gaskets, preventing leakage between flange surfaces and maintaining assembly integrity. For more than 60 years, Loctite gasketing products have helped industry to secure success by increasing reliability and preventing unscheduled and costly downtime and equipment failure.
The new oil-tolerant formula of Loctite 518 ensures a more consistent cure under real-world production and maintenance conditions, improving quality. It provides a higher strength on industrial surface contaminants and inactive flange substrates, simplifying the application process and reducing costs. Loctite 518 offers improved flexibility and adhesion to support thinner, lighter weight flange designs and its robust curing and durability provide better performance in harsh operating conditions.
Loctite 518 is a semi-flexible, medium-strength anaerobic gasketing material designed for use on casted iron, casted aluminum, and steel flanged mating surfaces. It fills gaps up to 0.25 mm and forms a semi-flexible, chemical-resistant seal that will not tear or decay. Parts disassemble easily, even after extended service by simply applying a cleavage load between the flanges. Loctite liquid gasketing products have excellent fluid resistance and eliminate the need for compression gaskets and o-rings while maintaining proper clamp load on the assembly.
