MITTEL 6703 is an acrylate “silicone-free” deaerating additive designed to prevent macrofoam and air bubbles in two-component polyurethane solvent-based paints, including topcoats and basecoats. It can be applied via spray or curtain coater, and its purpose is to modify the surface tension of the system. It can be added at any point during production by simple stirring.
