Abstract
A durable pigmented film, particularly intended for use in lieu of or as a replacement for conventional paint, is a composite film having a thickness of from about 1 to about 20 microns and comprised of a polymer matrix containing from about 15 to about 50% by volume of pigment particles. Methods of making and using the film are disclosed.
Claims19
A durable pigmented film comprising a polymer film having a thickness from about 1 to about 20 microns and containing from about 15 to about 50% by volume of pigment particles.
A durable pigmented film for use in lieu of or as a replacement for conventional paint comprising a composite film having a thickness of from about 1 to about 20 microns and comprised of pigment particles dispersed in a polymer matrix at a concentration of from about 15% to about 50% by volume.
A method of making a durable pigmented film comprising the steps of dispersing micro size pigment particles throughout a liquid polymer matrix at a ratio of from about 15 to about 50% by volume, applying the liquid pigmented polymer to a substrate at a thickness from about 1 to about 20 microns, curing the polymer to form a solid flexible film, and subsequently stripping the film from the substrate.
