The DuPont Molykote compound is used in many different applications such as lubrication for control and pressure plug valves, water softener and faucet valves. Sealant for vacuum and pressure systems and outdoor equipment (also shipboard) subject to washing and harsh environmental exposure, such as meters, electrical service entrance and underground connections. Damping medium for dash pots in electrical and electronic equipment. As an anti-stick and a sealant for transformer gasket and equipment enclosures – it prevents gaskets from sticking to metal and resists weathering and water washout. Also suitable for rubber and plastic O-rings, gaskets and seals.

Application Instructions:

Dow 111 Silicone Tube Valve Lubricant can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up; test prior to use.
A thinner consistency can be achieved by dispersing in solvents such as xylene, mineral spirits and Methyl Ethyl Ketone (2-Butanone). Dow 111 Silicone Lubricant can then be applied by brushing, dipping or spraying.
Dow 111 Silicone Lubricant should not be applied to any surface which will be painted or finished. Such coatings may not adhere to the silicone-treated surface. If contaminated by a silicone coating, parts can be wiped or washed with solvent, washed with detergent, or immersed in an alcoholic potassium hydroxide solution and then rinsed in clear water before painting.
