Detailed Product Description

MOLYKOTE® D-321 R Anti-Friction Coating is a premium air-cured lubricant coating engineered to enhance the performance and longevity of metal-to-metal combinations under extreme conditions. Formulated with molybdenum disulfide and graphite, this coating offers superior load-carrying capabilities and ensures reliable lubrication in high-stress environments.

This product is specifically designed for permanent lubrication in applications such as sliding guides, threaded connections, and oscillating components. It is widely used in industries ranging from automotive to renewable energy, where it ensures smooth operation during running-in, high vacuum, and extreme temperature conditions.

Common applications include cylinder-head bolts, car mirror adjustment mechanisms, toaster guides, and parts of wind turbine rotor heads. It also serves as an emergency lubricant for critical systems.

For a convenient aerosol application of this product, explore our MOLYKOTE® D-321 R Anti-Friction Coating Spray, which offers the same exceptional performance in an easy-to-use spray format.
