POLY/Solv RS-50 (RS-50) is a concentrated solution designed to economically and efficiently strip all

commercially available, fully aqueous dry film resists. RS-50’s unique formulation does not include sodium or

potassium hydroxide, glycol ethers, or alcohols (including methanol). As such, RS-50 is easier to waste treat

and exhibits less odor than many competitive products.RS-50 was formulated to produce stripped resist

particles averaging 0.2 – 0.5 cm in diameter, facilitating resist particulate filtration with a rotary drum filtrator

or equivalent. RS-50 also incorporates a unique blend of copper AND SOLDER inhibitor compounds to

reduce the attack of solder on hard boards and leave a bright, stable, oxide free copper surface.

Performance Features
  • Exhibits minimal chemical and/or galvanic corrosion attack on solder simplifying waste treatment of spent solutions and resist particulate.
  • RS-50 is highly concentrated and is effective at concentrations as low as 5% in spray applications.
  • Suitable for feed and bleed processing with an automated resist stripper controller such as Seacole’s Chemical Control System.
  • Designed for spray applications but effective in immersion tanks as well.
