Abstract

Additives formulating can be resource intensive and time consuming to paint manufacturers due to the plethora of ingredient combinations and interactions that affect performance properties.  These challenges may inhibit the efficacy of selected additives, which are particularly important in low volatile organic compound (VOC) formulations to address foam control, water sensitivity, and general surface properties.  Given their distinct chemistry, silicone additives in particular, are disproportionately influential in impacting film properties at low use levels.  The Dow Chemical Company has developed high throughput methodologies to screen and identify top performing additive candidates to address desired performance targets.  The use of slip/mar additives has been a recent area of focus, with high throughput methods aiding in the exploration of additive impact on properties that include friction coefficients, mar and abrasion resistance, hardness, surface defects, and clarity.  This work addresses the development of these methods and identifies top classes of silicone chemistries to balance desired film performance in wood coatings formulations.
