LOCTITE® 5188 is a high performance anaerobic flange sealant for use in rigid metal surfaces. It cures upon contact with metals and in the absence of air, providing a reliable seal even on contaminated or slightly oily surfaces.
LOCTITE® 5188 is a premium flange sealant designed for metal-to-metal bonding. Its anaerobic curing technology allows it to form a strong, flexible seal that fills surface imperfections on flanges, ensuring a leak-proof barrier. This product is particularly suitable for use on aluminum and other passive metals, offering robust resistance to high temperatures, oils, and a wide range of industrial fluids. With its tolerance for slight contamination (Such as oil residues), LOCTITE® 5188 enhances productivity in assembly processes where perfect cleanliness is difficult to maintain.
LOCTITE® 5188 is engineered to offer superior flexibility and gap-filling capabilities while resisting pressures, chemicals, and temperature variations. It eliminates the need for traditional gaskets, making it a versatile choice for industries requiring a strong and adaptable adhesive.
