Coating composition for use in high efficiency applicators

Abstract

A coating composition that includes 6 to 15 wt.% total solids, based on the weight of the coating composition; 15 to 70 wt.% based on the total solids, of core-shell resin particles; and 50 to 550 g / L, such as 100 to 500 g / L, or 150 to 450 g / L volatile organic compound (VOC) content. The coating composition can have a viscosity at 1000 s-1 of from 30 to 110 mPa·s and a viscosity at 0.1 s-1 of greater than 1000 mPa·s measured using an Anton-Paar MCR301 rheometer equipped with a concentric cylinder fixture (CC27 with gap size of 1.13 mm) at 25°C and a pressure of 101.3 kPa (1 atm). The total solids and VOC can be determined according to ASTM D2369 (2020) and ASTM 3960 (2005) respectively. The coating composition is capable of being applied using a high transfer efficiency precision applicator.
