Solution Overview

Problem

Existing protective films and laminates lack comprehensive performance in terms of chemical resistance, scratch and impact resistance, non-stick and non-wetting properties, anti-graffiti and anti-fouling properties, weather resistance, optical clarity, and flexibility for conforming to non-planar surfaces.

Innovation Solution

A surface-treated protective film or laminate with a solvent-based coating solution that penetrates the plastic substrate, using materials like POSS (Polyhedral Oligomeric Silsesquioxanes) to enhance properties such as chemical resistance, non-stick, and optical clarity, while maintaining flexibility and extensibility.

AI summary

A surface treatment for a protective plastic film and/or laminate is disclosed. Suitably, the surface treatment includes coating a major surface of the plastic film or laminate with a curable coating formulation wherein the one or more of the coating ingredients are diffused or migrated at least partially into the plastic film or plastic laminate. The migration of coating ingredients creates a gradual transition layer from the plastic film to the coating layer and leads to unique properties. Optionally, the surface treated plastic film is laminated to a release liner coated with a pressure sensitive adhesive (PSA) to form the aforementioned laminate.
