HumiSeal Stripper 1100

HumiSeal® Stripper 1100 is a unique stripper to remove dual cure acrylated urethane conformal coating such as UV40 family products. HumiSeal® Stripper 1100 does not contain any halogenated hydrocarbons, aromatics or flammable ingredients. Unlike methylene chloride based products that evaporated quickly, HumiSeal® Stripper 1100 remains on the surface to penetrate and soften the coating. HumiSeal® Stripper 1100 will not remove or attack solder, copper, silver, gold and nickel plating. HumiSeal® Stripper 1100 is in full compliance with the RoHS Directive (Directive 2002/95/EC).
Manufacturer: Humiseal

Directions for Use

Immerse the component or printed circuit board assembly into HumiSeal® Stripper 1100. The rate at which the existing coating will dissolve will depend upon its thickness and age. Most coatings of normal thickness will normally be completely removed in approximately up to 30 minutes or less. The use of mechanical mixers will speed up the dissolving rate. HumiSeal® Stripper 1100 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.
