LOCTITE® 515 is specially formulated anaerobic sealant, ideal for metal-to-metal bonding in rigid flange assemblies. It is desighned to cure when confined between two metal surfaces in the absence of air, forming a strong, flexible, and durable seal. This product is highly resistant to common industrial fluids like oils, water, and coolants, making it a versatile solution accross multiple industries. Its gap-filling capabilities and ability to withstand low pressure before full cure make it a preferred choice in maintenance and assembly applications.
