Anodized aluminum profiles are suitable for different types of protective films, the most common of which are the following: 1. Anodized film: Anodizing is a common aluminum surface treatment method. 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 […]
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 […]
Curing agents play a vital role in protective film products, primarily in the curing and hardening process of the film. Here are the main functions of curing agents in protective film products: 1. Facilitating chemical reactions: Protective films are typically composed of one or more substances that need to cure after being applied to the […]
There are several situations where a protective film is prone to tearing when being peeled off: 1. Fragile material: Some protective films may be made from fragile materials that are prone to breakage or tearing when peeled off. This could be due to the inherent characteristics of the material, such as polyethylene film, polyvinyl chloride […]
Indeed, a high-viscosity protective film may be needed for a frosted or rough surface. Frosted or rough surfaces are uneven and porous, requiring a stronger adhesion from the protective film. A high-viscosity protective film can better fill in the small indentations and pores on the surface and maintain a stable adhesion, ensuring effective protection. High-viscosity […]
