POLY/Solv RS-5 (RS-5) is a concentrated solution designed to economically and efficiently strip all commercially available, fully aqueous dry film resists. RS-5’s formulation does not include alcohols (including methanol). As such, RS-5 exhibits less odor than many similar products. RS-5 was also formulated to produce stripped resist particles averaging 0.4-1.0 cm in diameter in a conveyorized spray application, facilitating resist particulate filtration with rotary drum filtrator or equivalent. RS-5 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.
- Exhibits minimal chemical and/or galvanic corrosion attack on solder simplifying waste treatment of spent solutions and resist particulate.
- 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.
