Title: Gunter Osswald: Innovator in Pigment Preparation Technologies
Introduction
Gunter Osswald is a notable inventor based in Grossauheim, Germany. He has made significant contributions to the field of pigment preparation, holding a total of 4 patents. His innovative processes have advanced the production of pigment preparations, making them more efficient and effective.
Latest Patents
Osswald's latest patents include a process for the production of readily dispersible pigment preparations. This process involves creating an aqueous suspension with a pigment content exceeding 65%. The suspension is kneaded at temperatures between 60°C and 70°C, followed by the addition of a cation-active substance and an oleate. A binder dissolved in an organic solvent is then introduced, leading to a phase inversion that separates water from the mixture. After decantation, the organic mass of pigment is kneaded and dried.
Another significant patent is for the production of pigment-synthetic resin concentrates. This process entails the intensive mixing of an aqueous polymerizate-lyosol containing a dispersed pigment. Coagulation occurs through the addition of an electrolyte, allowing for the separation of the coagulate from the aqueous phase, which is then dried.
