Metstrip EF3461 has been developed as a safer paint stripping alternative to Methylene Chloride. While Methylene Chloride is an extremely effective paint stripping solvent, it has the disadvantage of a low Workplace Exposure Limit (WEL) of 100 ppm (long term) or 300 ppm (short term) and a low boiling point of 40°C, making it easy to reach these concentrations. Metstrip EF3461 has a much higher boiling point (206°C), so evaporation is much slower, even when used warm at 50°C. Metstrip EF3461 is most effective at removing polyester paints from steel and aluminium. For optimum performance, it is best used warm at 50°C, where it typically removes polyester paint in less than 10 minutes (depending on coating thickness and agitation). It can also be used at ambient temperatures, though stripping times will increase. Metstrip EF3461 is an alkali-activated solvent blend. Although it contains alkali, the attack on aluminium substrates is minimal due to the water-free nature of the solution.

Features and benefits:
Liquid product for use in tank immersion processes.
Causes polyester paint to disintegrate into fine particles rather than large flakes.
Low vapour pressure, reducing evaporation losses to the atmosphere.
Usually no need for forced extraction due to low evaporation loss.
Suitable for use on aluminium, steel, and zinc.
