Advances in Waterborne Rheology Modifiers: Improving Thickening Efficiency in Low to Zero VOC Architectural Paint Formulations

摘要

Improved thickening efficiency is the order of the day in the waterborne coatings. VOC regulations have driven latex manufacturers to develop new systems that allow formulators to be in compliance. Unfortunately, these new latex systems interact very differently with the functional additives and the rheology modifiers are typically much less efficient. In addition to the principles of rheology, the next generation of thickener technology discussed here is intended to offer the formulator options in resolving the issue of thickener inefficiency, while maintaining paint performance properties. These properties include color retention on tinting, color stability, sag resistance and leveling.
