The protective film also has the function of anti-fingerprint

Yes, one of the functional evolution of the protective film is to have the function of anti-fingerprint. Fingerprints are a mixture of oil and sweat produced by human skin, which is easy to leave obvious marks on surfaces such as touch screens and glass surfaces. In order to protect the screen or other surface from fingerprint contamination, some protective film products are designed to effectively reduce fingerprint attachment.

Anti-fingerprint protective film usually uses coating technology, the use of surfactants, silicone oil and other special materials to create a layer of film that can resist grease and fingerprints. These films can fill in tiny dents in the surface and inhibit the infiltration of oil, thus reducing the formation of fingerprints.

By using an anti-fingerprint protective film, you can make the screen or other protected surfaces look cleaner, while also reducing reflected light and smoothness on technology devices and high-finish products. This not only improves the appearance and texture of the product, but also provides a better display effect and touch experience.

The anti-fingerprint function of the protective film may vary between manufacturers and products. Therefore, when choosing an anti-fingerprint protective film, it is recommended to carefully understand the specifications and functional descriptions of the product, and choose the product that suits your needs.

In this process, a layer of alumina is formed on the aluminum surface by electrolyzing aluminum, forming a thin and hard protective layer. This oxide film can provide corrosion and wear resistance to aluminum, but usually does not provide other additional protective functions. Therefore, according to the specific needs, you can choose to apply other types of protective film on the oxide film.

2. Coating protective film: The anodized aluminum profile can be coated with different types of protective film, such as polymer coating film, coating paint, etc. These coatings can provide additional protection, giving aluminum profiles better weather, corrosion and wear resistance. Different types of coating films can be selected according to specific applications, such as coating films with fire protection, anti-pollution, anti-fingerprint, anti-UV and other properties.

3. Polymer protective film: Polymer protective film is a transparent protective film that can be covered on the surface of anodized aluminum profiles, providing wear-resistant, scratch resistant, anti-pollution and anti-ultraviolet radiation functions. This protective film is usually made of polyester film, polycarbonate film, polyurethane film and other materials, which can effectively protect the finish and appearance of the aluminum surface.

Select the appropriate protective film according to the specific requirements. Before selecting and applying the protective film, it is recommended to consult with a professional aluminum profile manufacturer, coating film supplier or technical expert to ensure that the selected protective film meets the expected requirements and provides the best protection for the anodized aluminum profile.

The adhesive strength of a protective film based on the substrate

Different substrates have different surface characteristics and physical-chemical properties, such as roughness, surface energy, chemical composition, etc. These characteristics directly influence the adhesion capability and stability between the protective film and the substrate.

Typically, for rough or porous substrates, a protective film with higher adhesive strength is needed to fill the indentations and pores on the surface of the substrate, ensuring good adhesion. A high adhesive strength protective film can provide more durable protection and resist external scraping and peeling forces.

Conversely, for smooth and sealed substrates, a protective film with lower adhesive strength may be more suitable. This reduces the contact area between the protective film and the substrate, avoiding the residue of adhesive substances when peeling off the protective film.

Special requirements of the substrate also need to be taken into consideration when selecting the protective film. For example, some substrates may be sensitive to specific chemical components, requiring the selection of film materials that meet their requirements to prevent mutual reactions or damage.
