METHOD FOR MANUFACTURING POLYMER FILM COATED WITH CURED POLYSILOXANE Russian patent published in 2016 - IPC B32B27/08 C08J7/04 C09J7/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for manufacturing mono- or multi-layered polymer film, provided from one side with a coating from thermally cured polysiloxane. The tubular, folded flatly in the form of a double cloth mono- or multi-layered polymer film on the basis of a thermoplastic polymer is first (a) covered with not yet cured polysiloxane on one its surface from one side, (b) the said polysiloxane coating is cured by heat impact in its drying, (c) still free, not covered second surface of the flatly folded in the form of a double cloth polymer film is covered with not yet cured polysiloxane, (d) the said polysiloxane coating is cured by heat impact in its drying and e) provided from each of both sides with a coating from cured polysiloxane, the tubular, flatly folded in the form of a double cloth, not yet longitudinally opened or still not completely longitudinally opened polymer film is completely opened in the longitudinal direction along the lateral edge, and provided from one side with a coating from cured polysiloxane, opened into a single-layered cloth of a double width film or each of the obtained two films, provided from one side with the polysiloxane coating films are stored in the wound into a roll form.

EFFECT: method improvement.
