Motorex Anti-Seize Description: The Motorex Anti-Seize Paste has an advanced formulation that works with steel and aluminum alloy components to make sure that they will not become chemically welded together over time. This unique paste creates a protective layer between two surfaces, and this paste is incredibly resistant to frictional corrosion, oxidation, and galling of the surfaces that are coming into contact with each other. If you are building up a steel bicycle, or have alloy components with steel hardware, this paste ensures that the installation of the parts and hardware is easy and future maintenance can be done without resorting to drastic measures to get them apart from one another. Features: Special mounting paste creates a protective layer between two differing metal surfaces (such as putting an alloy bottom bracket cup into a steel bicycle frame) that prevents micro-pitting and the buildup of corrosion Also resists contact corrosion by inhibiting the transference of ion's between different metals over time, which will prevent two different materials from becoming chemically welded together Creates a stronger connection between the joining parts, reducing the chances of parts loosening over time Water resistant so it won't wash away if exposed to foul weather Ideal for use when adding alloy components onto a steel bicycle frame, for fasteners getting threaded into a different material (like stem bolts or seatpost bolts), and components that need a press-fit or friction fit Jar lid includes a brush for less mess and easy application
