In 2010 a new concept for water-based DTM coatings - a superhydrophobic dispersion (SHD) - was introduced to the market  . This kind of polymer dispersion forms a perfect barrier against humidity, moisture and oxygen to prevent corrosion on metal surfaces. Instead of using active pigments such as zinc phosphate, SHD technology has the advantage of not requiring any compromises to achieve colloidal stability against bivalent cations (e.g. Zn 2+ ) for the polymer particles. This development also removed the label of "hazardous to the environment" that active pigments had required - so the new SHD can ...
