HumiSeal® Stripper 1090 is safe for use on printed circuit board assemblies. Some soft aluminums and rubbers may be sensitive to HumiSeal® Stripper 1090. Testing components for sensitivity prior to full immersion is highly recommended.

Directions for Use

Immerse the component or printed circuit board assembly into HumiSeal® Stripper 1090. The rate at which the existing coating will dissolve will depend upon its thickness and age. Heating HumiSeal® Stripper 1090 will increase its effectiveness significantly (Caution: Do not exceed 48°C max). Some silicone coatings may take as long as 8 hours to dissolve.
After the existing coating has been removed, thoroughly wash the assembly in isopropyl alcohol, deionized water or other qualified cleaning process. Oven dry the assembly for a minimum of 30 minutes at 66°C prior to recoating.

Handling Precautions

HumiSeal® Stripper 1090 is flammable and the following standard safety precautions should be observed:

  • Use only in well ventilated areas.
  • Protective gloves and goggles should be worn.
  • In case of prolonged skin contact, wash with water.
  • In case of eye contact, flush with water followed by a diluted boric solution and contact physician.
  • Avoid prolonged breathing of vapours.
  • Unused portions of HumiSeal® products must be disposed of in compliance with all applicable environmental regulations.
  • Consult the Material Safety Data Sheet (MSDS/SDS) for more specific product information.
