MULTILAYER SURFACING FILMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18289265 titled 'MULTILAYER SURFACING FILMS

The surfacing film described in the patent application consists of multiple layers, including a clear coat layer made from a crosslinked polyurethane, a bulk layer made from a thermoplastic polyurethane, and an adhesive layer. Optionally, a second clear coat layer can be included, made from a polyurethane that is partially crosslinked.

• The first clear coat layer is a reaction product of an isocyanate and a polyol containing a styrene repeat unit and a hydroxyl-containing (meth)acrylate repeat unit.
• The surfacing film displays high stain resistance, high peel strength, superior scratch resistance, and self-healing properties.

Potential Applications: - Automotive industry for vehicle coatings - Electronics industry for protective films on screens - Furniture industry for scratch-resistant coatings

Problems Solved: - Stain resistance - Peel strength - Scratch resistance - Self-healing properties

Benefits: - Enhanced durability - Improved aesthetics - Long-lasting protection

Commercial Applications: - Automotive coatings - Electronics protective films - Furniture coatings

Questions about the technology: 1. How does the surfacing film achieve self-healing properties? 2. What industries can benefit the most from using this innovative film technology?

Frequently Updated Research: - Ongoing studies on improving the scratch resistance of the surfacing film - Research on enhancing the self-healing properties of the film.

Original Abstract Submitted

Provided is a surfacing film that includes a plurality of layers. The layers include a first clear coat layer made from a crosslinked polyurethane that is a reaction product of a reactive mixture including an isocyanate and a polyol containing a styrene repeat unit and a hydroxyl-containing (meth)acrylate repeat unit. The surfacing film further includes a bulk layer made from a thermoplastic polyurethane and an adhesive layer. Optionally, the surfacing film includes second clear coat layer, which can be made from a polyurethane that is at least partially crosslinked. The resulting surfacing film can display high stain resistance, high peel strength, superior scratch resistance and self-healing properties.
