Mechanical equipment in hostile environments may benefit from additives to ensure smooth movement at all speeds and long-term reliability. Examples are camera parts, valves, plastic gears and linkages in aerospace service. Purity and lack of reactivity are benefits in food processing equipment. Systems requiring low starting torque without stick-slip action or where long periods of inactivity (safety valves and taps) are required benefit from Zonyl® fluoroadditives, at up to 40 percent loading which provide fail-safe security if other lubrication components fail.
Oils are a large family of products. They provide one or more functions such as lubrication, cooling, transferring energy or motion, and insulating electrical devices. Zonyl® fluoroadditives have the potential for providing solid lubricant particles without affecting other functions.
Zonyl® fluoroadditives are sometimes used in formulations made for addition to the lubricating oil in internal combustion engines or other machinery using high performance oil. The chemical and thermal stability of PTFE particles is important to this use.
MP1100 is a good candidate for the formulation of a stable colloidal dispersion because it can break down into very small particles when sheared in a liquid medium. Also, a liquid based "concentrate" can be used to facilitate good distribution into a much larger quantity of a liquid host material.
Direct Use for Lubricants
Zonyl® fluoroadditives can be applied directly as dry powder, spray, or paste. Sliding surfaces or woven structures are easy to lubricate, and Zonyl® fluoroadditive powder is much cleaner than graphite or molybdenum disulfide powder and less contaminating than silicones. Uses include cables, rope, glass cloth, fibrous packings, window slides, and security locks. Visit the Krytox® web site for information on fluorinated oils and greases.
Direct Use for Sealants
Pipe thread sealant paste containing Zonyl® fluoroadditives can be made with a simple hydrocarbon carrier or with a thermosetting resin, providing easy release even after long service.
