HumiSeal® Stripper 1072 is safe for use on copper, gold, silver or nickel plating, steel, brass, bronze, phenolic resins, amine cured epoxies, polyethylene, Teflon, Kel-F, neoprene, or vulcanized rubber. It will attack anhydride-cured epoxies and most silicones. It will either swell or dissolve polystyrene, vinyl, plexiglas, and acrylics.

Directions for Use
Immerse the component or printed circuit board assembly into HumiSeal® Stripper 1072. The rate at which the existing coating will dissolve will depend upon its thickness and age. Heating HumiSeal® Stripper 1072 will increase its effectiveness (Caution: do not exceed 48°C max). The use of mechanical mixers will speed up the dissolving rate. HumiSeal® Stripper 1072 can also be used to remove coating from small areas, by applying a few drops to the desired location.

After the existing coating has been removed, thoroughly wash the assembly in isopropyl alcohol, deionized water or other qualified cleaning process. If the component surface of is cloudy after washing, the removal is incomplete. The removal should be repeated for a longer time. Oven dry the assembly for a minimum of 30 minutes at 66°C prior to recoating.
