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