Latest Patents

One of his latest patents is for an aqueous non-blocking tinter for paints. This invention addresses the issue of dispensing nozzles becoming blocked, providing a tinter with a viscosity ranging from 0.05 to 1.5 Ns/m² at 20°C. The formulation includes pigment particles, water, micellising dispersant, and a non-micellising auxiliary material. The weight ratio of dispersant to pigment is crucial, exceeding the ratio present at the Daniel Flow Point for a notional tinter. Additionally, the tinter is designed to be expelled through a bore of 2 mm in diameter and 15 mm long under specific pressure conditions after storage.

Another significant patent involves amphipathic copolymer pigment dispersants. This invention features a co-polymer with a weight average molecular weight between 2,500 and 20,000. It comprises an addition polymer backbone and stabilizer units, ensuring a balanced proportion of functional and non-functional structural units. The careful design of hydroxy groups, carboxyl groups, and stabilizer units enhances the performance of the dispersants in various applications.
