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.

A composite film comprising:
- a substrate, and
- a protection coating overlying the substrate, wherein the protection coating comprises:
- a urethane acrylate 6-functional oligomer, and
- a urethane acrylate 2-functional oligomer,
- wherein the protection coating comprises 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.
A composite film comprising:
- a substrate, and
- a protection coating overlying a first surface of the substrate, wherein the protection coating comprises:
- a urethane acrylate 6-functional oligomer at a content of at least about 10 wt. % and not greater than about 75 wt. % for a total dry-weight of the protection coating, and
- a urethane acrylate 2-functional oligomer at a content of at least about 5 wt. % and not greater than about 50 wt. % for a total dry-weight of the protection coating.
A composite film comprising:
- a substrate, and
- a protection coating overlying a first surface of the substrate, wherein the protection coating comprises:
- a urethane acrylate 6-functional oligomer, and
- a urethane acrylate 2-functional oligomer,
- wherein the protection coating has a surface energy of at least about 20 mN/m and not greater than about 50 mN/m.
