POLY/Solv RS-40 (RS-40) is a concentrated, monothanolamine based solution designed to economically and efficiently strip all commercially available, fully aqueous dry film resists. RS-40’s unique formulation does not include sodium, potassium or ammonium hydroxide, glycol ethers, or alcohols (including methanol). As such, RS-40 is easier to waste treat and exhibits less odor than many competitive products.
RS-40 was formulated to produce stripped resist particles averaging 0.2-0.5 cm in diameter, facilitating resist particulate filtration with rotary drum filtrator or equivalent. RS-40 also incorporates a unique blend of inhibitors and copper anti-tarnish 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.
- RS-40 is highly concentrated and is effective at concentrations as low as 5% in spray applications.
- Suitable for feed and bleed processing with Seacole’s automated resist stripper controller.
- Designed for spray applications but effective in immersion tanks as well.
