Low VOC Multifunctional Additives to Improve Water-Based Polymer Film Properties

摘要

The low VOC multifunctional additive blend has increased hardness, hardness progression, scrub resistance, block resistance, dirt pickup resistance, wet adhesion and resistance to, among other properties, adhesion. It provides corrosion resistance (flash rust resistance) to water-based coatings or other water-based polymer film forming compositions and consists of known low volatility coalescents formulated with certain high volatility components, some of which are It is neither known nor used heretofore as a fusing agent. It has been found that the blends of the present invention act synergistically to provide a low VOC content to the formulation, while providing fusion and unexpected property improvements of water-based polymer formulations. The present invention also relates to a method for incorporating organic acids into water-based coatings to improve the properties of water-based polymer systems and to improve flash rust resistance, among other properties, through the use of the low VOC multifunctional additive blend of the present invention. .
