Method for decreasing pollution resulting from the application of a coating composition

Claim 1

A method for decreasing air pollution resulting from the application of coating compositions comprising the steps of: 1. applying to a substrate an organic solvent based coating composition containing a completely water miscible organic based solvent thinner composition, thereby forming a gaseous effluent containing a mixture of air and gaseous organic solvent and gaseous thinner, wherein the water miscible organic based solvent thinner composition is comprised of: (a) a water miscible compound selected from the group consisting of a saturated aliphatic glycol or a saturated aliphatic glycol ether, both containing at least three carbon atoms, and a compound containing Formula I: R--O[CH.sub.2 (R.sub.1)--O].sub.n R.sub.2 I wherein R is independently selected from the group consisting of hydrogen, alkyl of from 1 to 4 carbon atoms and --(O)C--CH 3 ; R 1 is independently selected from the group consisting of --CH 2 , --CH 2 --CH 2 --, --CH 2 --CH(CH 3 )--, and --CH(CH 2 OH)--; R 2 is independently selected from the group consisting of alkyl of from 1 to 4 carbon atoms, hydroxyl substituted alkyl of from 1 to 4 carbon atoms and --(O)C--CH 3 ; and n is a number from 1 to 4; and mixtures thereof, in an amount ranging from about 10 to about 60 parts by weight (PBW); (b) a water miscible monoalcohol having from 1 to about 8 carbon atoms, in an amount of about 10 to about 60 PBW; and (c) a water miscible saturated aliphatic ketone of up to 12 carbon atoms in an amount of about 10 to about 50 PBW, the total of a+b+c equaling 100 PBW; and 2.

Claim 2

A method for decreasing air pollution resulting from the application of coating compositions comprising the steps of: 1. applying to a substrate an organic solvent based coating composition containing a completely water miscible organic based solvent thinner composition, thereby forming a gaseous effluent containing a mixture of air and gaseous organic solvent and gaseous thinner, wherein the water miscible organic based solvent thinner composition is comprised of: (a) a water miscible compound selected from the group consisting of a saturated aliphatic glycol or a saturated aliphatic glycol ether, both containing at least three carbon atoms, and a compound containing Formula I: R--O[CH.sub.2 (R.sub.1)--O].sub.n R.sub.2 I wherein R is independently selected from the group consisting of hydrogen, alkyl of from 1 to 4 carbon atoms and --(O)C--CH 3 ; R 1 is independently selected from the group consisting of --CH 2 , --CH 2 --CH 2 --, --CH 2 --CH(CH 3 )--, and --CH(CH 2 OH)--; R 2 is independently selected from the group consisting of alkyl of from 1 to 4 carbon atoms, hydroxyl substituted alkyl of from 1 to 4 carbon atoms and --(O)C--CH 3 ; and n is a number from 1 to 4; and mixtures thereof, in an amount ranging from about 10 to about 60 parts by weight (PBW); (b) a water miscible monoalcohol having from 1 to about 8 carbon atoms, in an amount of about 10 to about 60 PBW; and (c) a water miscible saturated aliphatic ketone of up to 12 carbon atoms in an amount of about 10 to about 50 PBW, the total of a+b+c equaling 100 PBW; and 2.
