  • COMPOSITE FILM AND METHODS OF FORMING A COMPOSITE FILM
    Publication number: 20230303787
    Abstract: According to one aspect, a composite film may include a substrate, and a protection coating overlying the substrate. The protection coating may include a urethane acrylate 6-functional oligomer, and a urethane acrylate 2-functional oligomer. The protection coating may further include a urethane acrylate oligomer ratio UAC6/UAC2 of at least about 0.5 and not greater than about 3, where UAC6 is equal to the content of the urethane acrylate 6-functional oligomer in wt. % for a total weight of the protection coating and UAC2 is equal to the content of the urethane acrylate 2-functional oligomer in wt. % for a total dry weight of the protection coating.

  • MULTIFUNCTIONAL FILM
    Publication number: 20210394465
    Abstract: The present disclosure relates to a multifunctional film for a vacuum bag that may include a flexible barrier film that may include a textured surface. The multifunctional film may further include a release coating overlying the textured surface of the flexible barrier film. The multifunctional film may further have an oxygen (O2) permeability of not greater than about 1100 cc/(m2-day-atm) and a stability rating of not greater than about 90%, where the stability rating is defined as the maximum percent decrease in elongation at break as measured using ASTM D882 after being exposed to a temperature of 200° C. for 12 hours.
