PROCESS FOR THE PRODUCTION OF AN OEM BASE COAT/CLEAR TOP COAT MULTI-LAYER COATING

摘要

A process for the production of an OEM base coat/clear top coat multi-layer coating wherein a waterborne base coat composition is spray-applied by electrostatically-assisted high speed rotary atomization, wherein the waterborne base coat composition comprises binder solids comprising about 20 to about 100 wt. % of an aqueously dispersed polyurethane urea resin with a carboxyl number of about 10 to 50 mg KOH/g.
