The ACCUMETRIC boss-33512 is a 12 fl oz aerosol gun foam cleaner formulated to flush and clean dispensing guns used with polyurethane foam sealants. It removes uncured foam residue from gun mechanisms, nozzles, and internal passages before the foam hardens. Packaged in a pressurized aerosol can, it delivers solvent directly into the gun body for fast, thorough purging. Licensed contractors and professional installers working with spray foam and gun-applied construction sealants rely on this product as a routine maintenance item to extend the service life of their application equipment.
This cleaner is used in residential and commercial construction settings wherever gun-applied polyurethane foam is part of the workflow. Typical applications include air-sealing, insulation work, window and door rough opening work, and general construction sealant applications. It is applied immediately after foam dispensing while residue is still uncured, or used during scheduled gun maintenance to clear partially set material from the dispenser.
Listed as a direct replacement for DOW-259205. Suitable for use with standard construction foam dispensing guns as a routine cleaning and maintenance solvent.
Use immediately after foam dispensing while residue remains uncured for best results. Always flush the gun in a well-ventilated area and away from open flame, as aerosol solvents are flammable. Wear appropriate PPE including solvent-resistant gloves and eye protection during cleaning. Dispose of used solvent and empty aerosol cans in accordance with local regulations.
