Advantages in comparison with analogs: the technology allows to reduce the specific consumption of cellulose in the production of paper for printing; to increase the use of hardwood cellulose in the composition; replace imported oxidized starch with domestic one when preparing compositions for surface sizing
Form of intellectual property protection: RB patents: 10650 “Composition for surface sizing of paper for printing”, 13858 “Method for modifying carbonate filler in the manufacture of paper for printing”
Proposals for cooperation with investors: an agreement for the implementation of work on the implementation of the developed technology or its individual solutions for other enterprises producing paper and cardboard
