Best Practices for Dow 4 Electrical Insulating Compound
Dow Corning 4 Compound 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.
Dow Corning silicone compounds can be applied by hand, by specially designed automated equipment, or by brushing or wiping. When using some high pressure dispensing equipment, separation and compaction can occur. Certain designs of grease guns may seize with silicone compounds
test prior to using.
Where a thinner consistency is needed, the compound can be dispersed in a solvent and applied by brushing or spraying.
Because each application may vary in chemical composition, pressure, flow velocity, relubrication requirements and equipment design, the silicone compound should be tested before adopting for regular use.
