Loctite 5920 Gasket Sealant Copper Oxime Silicone Paste for Pipe & Thread Jointing 350°C 235479

Loctite 235479 5920 Gasket Sealant is a copper-coloured oxime silicone based sealant paste formulated for effective pipe and thread jointing. It withstands low-pressure online tests prior to full curing, filling surface voids and irregularities to create a reliable seal. The sealant adheres well to a variety of substrates including metals, glass, natural and synthetic fibres, wood, ceramics, silicone rubbers, painted surfaces, and many plastics, making it highly versatile for multiple industrial applications.

The product cures quickly within 0.5 hours and exhibits excellent resistance to automotive engine oils, which ensures longevity and durability in harsh environments. Its low modulus provides high flexibility, helping to absorb vibrations and mechanical stresses without cracking. Non-corrosive and low odour, the paste is safer and easier to work with in industrial settings. It operates effectively in temperature ranges from -60°C to 350°C, suitable for demanding applications.

Ideal for gasketing, jointing, and moisture curing jobs, the sealant is specially designed for use with flexible flanges. It also serves electrical insulating functions due to its chemical composition. The copper colour enhances visual identification during application and inspection.
