Concentrate composition and process for removing coatings from surfaces such as paint application equipment

摘要: A concentrate composition for removing coatings from surfaces such as paint application equipment is provided, which comprises: (a) 0 to 99.5 percent by weight of acetone, methyl acetate and/or water; (b) 0.01 35 at least one surfactant selected pyrrolidone-derived surfactants having substituents containing 6 14 carbon atoms and alkoxylated acetylenic compounds; (c) 0.5 90 pH adjusting component ammonia amines alkanyl groups, hydroxyalkanyl or aminoalkanyl groups 1 8 atoms. The volatile organic compound (VOC) content the less than 2.0 lb./gal. Also provided a process comprising diluting described above with water form cleaning solution; contacting solution until coating residues are substantially removed surfaces.
