With a total of 2 patents, Schwan has focused on developing advanced aqueous coating agents that enhance various applications.

Latest Patents

Schwan's latest patents include a process for the manufacture of aqueous coating agents. This process involves mixing an aqueous dispersion of one or more water-dispersible or water-soluble binders that contain groups reactive with isocyanate. These binders are combined with one or more polyisocyanates, which may be liquid or present in liquid form due to the addition of organic solvents. The formulation may also include pigments, fillers, and customary lacquer additives. The resulting aqueous dispersion utilizes binders with a number-average molecular weight (Mn) ranging from 1000 to 100,000, with reactive groups equivalent to a hydroxyl number of 20 to 250 and an acid number of 10 to 100. The acidic groups are partially neutralized by polyamines mixed with tertiary monoamines, ensuring the polyisocyanate is dispersed shortly before use.
