Formulated from bentone clay, AP-1 is noted for its high temperature insensitivity, its non-melting and does not thicken excessively at temperatures as low as 0F (-18C). It has mechanical stability, is water resistant, displays high stability, provides excellent adhesion to metals, prevents wear and has superior storage life. AP-1 contains oxidation inhibitors, corrosion inhibitors and metal deactivators. It offers positive protection for extreme services, which require heavy duty lubricant performance. Ideal for oven chains.
