Resiflow L-66F is a high viscosity, carboxyl functional polyacrylate flow control agent. It can be used in a variety of coating systems and provides exceptional clarity in clearcoat systems. As with the other two carboxyl functional flow control agents in this group of specialty additives, Resiflow L-64F and L-65F, the typical dosage of Resiflow L-66F is 0.2 – 1.5% based on binder solids. Laboratory evaluation is required for each formulation to determine the best processing method and the optimum concentration of the additive. For powder coating clearcoat applications, Resiflow L-66F is available in a polyester resin masterbatch.
