COMPOSITION FOR COATINGS BASED ON FLUORINATED POLYACRYLATE, METHOD FOR PRODUCING IT AND ITS APPLICATION Russian patent published in 2023 - IPC C08G18/50 C09D127/12 C09D175/14 C09D133/04 

FIELD: oligomers.

SUBSTANCE: present invention relates to a composition comprising a fluorinated polyurethane acrylate resin and a polyurethane acrylate resin which, after curing, is durable and has stain prevention and scratch prevention properties. The composition contains an oligomer derived from an isocyanate, diol or polyol and a monomer which has at least one double bond and at least one hydroxyl group, and another oligomer derived from an isocyanate, diol or polyol, a fluorinated diol or a polyol or perfluoropolyether containing at least two hydroxyl groups; and a monomer that has at least one double bond and at least one hydroxyl group. The present invention also relates to oligomers obtained during the synthesis, as well as to the use of the composition or oligomer in the preparation of a coating on a substrate. The preparation of the composition is carried out using a one-pot multicomponent synthesis method, where several components are placed together to carry out simultaneous reactions.

EFFECT: this method is particularly suitable for production on an industrial scale and is flexible in terms of the introduction of additional components to further adjust the characteristics of the resulting composition.
