His work focuses on creating stable and high-solids aqueous dispersions, which have important applications in various industries.

Latest Patents

One of Dirk Reichel's latest patents involves the development of stable and high-solids aqueous dispersions of blocked polyisocyanates. This innovative process includes preparing a solution of a polyisocyanate mixture, which consists of 20-70% by weight of a blocked, hydrophilically modified polyisocyanate and 30-80% by weight of a blocked, hydrophobic polyisocyanate in an auxiliary solvent. The method further involves adding water to this solution with intensive mixing, resulting in a two-phase system that comprises a disperse polyisocyanate phase and a continuous aqueous phase containing auxiliary solvent. In a preferred embodiment, the dispersions are prepared to be virtually free from auxiliary solvent by first adding a portion of water, substantially removing the auxiliary solvent, and then adding a second portion of water with intensive mixing.
