Abstract

Low VOC multifunctional additive blends provide, in addition to coalescence, increased hardness, hardness development, scrub resistance, block resistance, dirt pickup resistance, wet adhesion, and corrosion (flash rust) resistance, among other properties, to waterborne coatings or other waterborne polymer film-forming compositions, and are comprised of known low volatile coalescents in combination with certain high volatile components some of which were not known nor heretofore utilized as coalescents. The inventive blends have been found to act synergistically to provide coalescence and unexpected improvement in properties of waterborne polymer formulations, while still providing a low VOC content to the formulations. The invention is also directed to methods for improving the properties of waterborne polymer systems and for incorporating organic acids into waterborne coatings to enhance flash rust resistance, among other properties, through use of the low VOC multifunctional additive blends of the invention.

Abstract

Unique 3-PPB monobenzoate analogs useful as plasticizers in polymeric dispersions, such as plastisols, melt compounds, and adhesives among other applications. The analogs are structurally similar to and/or derived from 3-phenylpropyl benzoate and heretofore were not known for use in industrial applications, particularly not as a plasticizer in polymeric applications including without limitation plastisols and adhesives. Depending on the application, the advantages rendered by the use of the inventive monobenzoate analogs include, among other things, excellent solvating properties and rheology, low viscosity and significantly improved viscosity over time, comparable or improved Tg suppression, set and open times, as well as health, safety and environmental advantages, over traditional plasticizers.
