Abstract
Polymeric compositions comprising polyvinylidene fluoride and one or more acrylic components are described. The compositions can be formed into films which do not require a carrier or other backing. Also described are methods for forming the films and applications for the films.
Claims36
A composition comprising:
- from 50% to 99% of at least one polyvinylidene fluoride polymer;
- from 1% to 50% of at least one acrylic component;
- from 0% to 5% of at least one supplemental resin;
- from 0% to 15% of at least one plasticizer;
- and
- an effective amount of solvent.
A method for forming a polyvinylidene fluoride film, the method comprising:
- providing a composition including from 50% to 99% of at least one polyvinylidene fluoride polymer, from 1% to 50% of at least one acrylic component, from 0% to 5% of at least one supplemental resin, from 0% to 15% of at least one plasticizer, and an effective amount of solvent;
- providing a substrate defining at least one face;
- forming a layer of the composition on the face of the substrate;
- performing at least one of drying and fusing of the layer to thereby form the polyvinylidene fluoride film.
An unsupported film free of a carrier, the film including a cured composition, the composition prior to curing having from 50% to 99% of at least one polyvinylidene fluoride polymer and from 1% to 50% of at least one acrylic component, wherein the film has a thickness in a range of from 0.1 mil to 5 mil and can undergo an elongation of up to 5% without breaking or fracturing.
