Cost-Saving, Renewable Dispersant Technology

摘要

Raw material cost increases, regulatory compliance and end-user market demand for more environmentally friendly products are some of the challenges faced by paint formulators. The Archer Daniels Midland Company (ADM) is addressing these needs by introducing cost-effective pigment dispersants derived primarily from renewable resources. This article provides an overview of the new dispersant technology, its chemistry and mode of action, presentation of results obtained from testing in model formulations, and a discussion on advantages over current industry practice. The test results support claims that these dispersants can be used to formulate paints with lower cost and excellent stability, together with improved color acceptance, contrast ratios, scrub resistance and enhanced hard water tolerance with less susceptibility to formulation failure from raw material quality variation.
