Technical specifications
FIPROSTRIP 291 is an alkaline paint stripper suitable for removing paints, resins and organic films from iron surfaces. Specifically designed for paint stripping operations where products with chlorinated solvents (methylene chloride) are not accepted.
FIPROSTRIP 291 quickly removes transparent, lacquered and pigmented paints from spectacles, metal profiles, tanks and artefacts.
The product is also suitable for use on plastic materials. However, due to the wide variety of plastics available on the market, we recommend that a compatibility test be carried out beforehand by soaking a sample of the material in FIPROSTRIP 291 for a few hours.
