There continues to be renewed focus on waterborne alkyd resins due to advancements in their chemistry, as well as increased interest in green chemistry.

The challenges of substrate wetting and flow are especially problematic for formulators of water-based coatings.

This article discusses the three types of OPVs and emphasizes the use of cellulose esters as additives to improve flow and leveling, and in many cases adhesion.

Troy Corp.’s multifunctional Troysol™ LAC provides excellent wetting of low-energy and contaminated surfaces, resulting in strong adhesive bonding.

The choice of wetting agents used in architectural coatings can have a significant impact when formulating low- to zero-VOC paints.
