Automotive coatings have witnessed a definite transition to greener technologies over the past decade. Paint lines are being built or retrofitted for consolidated paint processes, with the intent to reduce energy consumption and operating cost. Specific to automotive clearcoats, there is a move to a one-pass application and a continuing shift to higher solids clearcoats. Consolidated paint processes require a clearcoat with improved strike-in resistance, better flow/leveling, and "filling" power to cope with telegraphing from imperfect substrates. One-pass application requires a clearcoat with an improved sag/flow balance. This article illustrates the improved appearance achieved by the use of cellulose ester rheology additives, alone or in combination with other rheology modifiers, in automotive OEM IK clearcoats. Electrostatic rotary bell application was utilized to assess clearcoat appearance. Flow and leveling were characterized by a BYK Wavescan Dual, the viscoelastic behavior of clearcoats during the film drying process was investigated using a novel rheological technique, and the speed of solvent release was monitored using thermogravimetric analysis (TGA).
