Abstract
One exemplary embodiment may include a coating composition including an additive to prevent or hinder at least one of the coating or an underlying substrate from destabilization upon exposure to electromagnetic radiation.
Claims36
A coating composition for forming a protective or decorative coating over a substrate comprising:
- a polymer or monomer, a solvent, and an additive capable of absorbing energy from electromagnetic radiation having wave lengths in the ultraviolet light and visible light range.
A product comprising:
- a substrate and a protective or decorative coating over the substrate, the coating comprising a cured polymer and a first additive capable of absorbing energy from electromagnetic radiation having wave lengths in the ultraviolet light and visible light range, wherein the first additive comprises benzotriazole having the chemical formula C6H5N3 in an amount equal to or less than 3% by weight of the cured polymer.
