IPC: C09D7/12 , C09D121/02
CPC classification number: C09D7/63 , C07C69/67 , C08K5/10 , C08L31/00 , C09D5/00 , C09D7/61 , C09D7/65 , C09D121/02
Abstract: The invention is comprised of a coalescent and non-ionic surfactant blend additive for use in water-based architectural coating formulations. The dual-function blend is produced by reacting 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate with ethylene oxide in the presence of a basic catalyst and separating the desired ethoxylated coalescent and non-ionic surfactant blend from the reaction product.
