Chemical reaction and processing of aluminum surface protective film
- Jan 10, 2019 -

The adhesive of the aluminum surface protective film is inert and does not chemically react with the surface of the material to be bonded. The aluminum surface protective film has a low crystal point, and the fewer the crystal points, the higher the manufacturing level of the protective film, and the quality of the protective film. It will be better.

The aluminum surface protective film has good adhesion property to the material to be protected during use, and the protective film does not rise and fall off during material handling and processing. The protective film has good weather resistance and stability of holding force. After several days or a long time, the peeling force is not significantly increased, and it is easy to remove. On the surface to be protected, no residual glue remains and no shadow is required.

The aluminum surface protective film is, to a certain extent, a tensile strength, an elastic modulus, an elongation, and the like that fully meet the requirements of the user. To choose a protective film, you must master some selection techniques such as distinguishing materials. The key to the quality of the protective film is determined by the properties of the colloid. There are two types of pressure sensitive adhesives for protective films: solvent-based polyacrylate adhesives and water-soluble polyacrylate adhesives, which have different properties.
