How to use
Dow Corning / Molykote 4 Electrical Insulating Compound can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up with silicone compounds; test prior to use.
A thinner consistency can be achieved by dispersing in solvents such as xylene, mineral spirits and methyl ethyl ketone. Dow Corning / Molykote 4 Electrical Insulating Compound can then be applied by brushing, dipping or spraying. Dow Corning / Molykote 4 Electrical Insulating Compound should not be applied to any surface that 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.
Dispensing
Separation and compaction can occur with some high-pressure dispensing equipment. This should be considered when designing dispensing systems for use with Dow Corning / Molykote 4 Electrical Insulating Compound.
