Latest Patents

Mikkonen's latest patents highlight his ingenuity and commitment to sustainable solutions. One such patent is for a "Starch-based filler and coating pigment composition for fiber webs and method for the manufacture thereof". This invention involves a process where a feed comprising organic polymer material is cooled to an extremely low temperature of approximately -50°C. The material undergoes refinement in a jet refiner to achieve the desired particle size, resulting in uniform pigment particles made from starch esters. These particles possess a porous surface structure, making them ideal for use as coating pigments and fillers in offset and ink-jet papers.

Another notable patent focuses on "Pigment and filler and a method of manufacturing it". This invention introduces a biodegradable organic pigment and filler, crafted through preparing a solution containing a starch derivative. The solution is then contacted with a non-solvent to precipitate the starch derivative, yielding a dispersion of 100-300 nm spherical particles suitable for use as pigment, along with a coral-like, porous product that excels as a filler.
