Smooth and homogenous coating surfaces, in particular for high quality applications such as automotive and industrial coatings, are manufactured by means of small amounts of levelling and wetting agents. For an excellent substrate wetting the fundamental requirement of these additives is the efficient reduction in surface tension of the liquid coating formulation. As previously shown, tailored polyacrylate based block copolymers (BCPs) exhibiting a fluoro-modified block are able to wet difficult substrates efficiently and allow for the formation of thin, defect-free coating layers [1, 2, 3]. The requirements of the coating industry, however, focuses increasingly on additional coating functionalities. ...
