==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.
