Latest Patents
Ray's latest patented inventions include "Self-dispersing pigment and process of making and use of same." This innovative process involves the oxidation of pigment with ozone in an aqueous environment, where the mixture undergoes a dispersive mixing operation. This technique allows the pigment to be self-dispersing while maintaining a pH range of 6-8, ultimately achieving an acid value of less than 3 µmoles/M. Additionally, pigments produced from this process are applicable in inkjet inks, enhancing their performance.
Another notable patent is for a "Polyimide film with tin or tin salt incorporation resulting in improved adhesion and thermal durability." This polyimide film boasts improved properties due to the incorporation of 0.02 to 1% by weight of tin, enhancing its adhesion and thermal durability. The process for preparing this advanced film involves introducing a tin (II) or tin (IV) salt into a film-forming polyamide acid polymer prior to casting.
