APEO-Free and Low/0VOC Additives for Water-Based Coatings
By Linda Adamson of Solvay
While pigments and resins are the dominant materials used in water-based architectural coatings, additives are components of the formulation that are added in small amounts to provide special properties to the wet paint as well as the dry film. In particular, surfactants affect the behavior of paint not only during the lifetime of the formed coating, but also the initial aggregation and film formation of the paint. Surfactants not only allow the paint to coat a surface more easily due to increased wetting of ability of the coating, but are also critical in providing good color acceptance, stability, and other application requirements.
However, over the last decade, APE-containing (Alkyphenol Ethoxlate) surfactants are being replaced by APE-free surfactants due to biodegradability, toxicity of degradation products, bioaccumulation, and possible endocrine disruptor. As such, APE-free surfactants are needed that will not only address the environmental and health concerns, but also perform similar to APE-containing materials.
This presentation will cover the use of surfactants in the paint can, their primary role in performance benefits, and demonstrate several APEO-free surfactants as excellent alternatives to current APE- containing products for both the paint can and in pigment dispersions.
Linda Adamson is a Technical Manager for Performance & Color Solutions for Solvay, based at their Research and Innovation Center in Bristol, Pa., where she supports specialty additives for paint and pigments for water-based coatings. Prior to Solvay, Linda was the Technical Service Manager for Wall Coatings for Dow located in Collegeville, Pa. and started her 40 year career in coatings at Rohm and Haas in Spring House, Pa. Linda was part of a team of scientists who won the 2017 American Chemical Society “Heroes in Chemistry” Award and was also a recipient of the 2013 Presidential Green Chemistry Challenge Award. Linda has a B.S. in Chemistry from Philadelphia University, has several patents, co-authored several articles, and has taught courses at World of Concrete and FSCT.
