The surface protection of the aluminum profile is usually made of a polyolefin plastic film as a base material and an acrylate polymer as a matrix resin of a pressure sensitive adhesive, which is processed by a coating machine. It is a film-like material with surface protection and is one of the most important products in pressure sensitive adhesives. A temporary protective measure taken to prevent surface scratches during the process of storage, distribution, or processing of substrates.
The surface protection of aluminum profiles is widely used in the surface protection of aluminum plates, aluminum-plastic composite panels, mirror steel plates, color plates, plexiglass plates, decorative panels, and aluminum profiles, plastic steel profiles, stainless steel coils, marble materials and display screens. The aluminum surface has soft surface protection properties, good adhesion, easy adhesion and easy peeling. The pressure sensitive adhesive has good stability and does not have any adverse effect on the surface of the product to be attached.
The surface protection of aluminum profiles is divided into two parts: film and colloid. The film is generally made of low-density polyethylene and polyvinyl chloride. It can be obtained by extrusion molding, injection molding, and blow molding. The key to the surface protection of aluminum profiles is determined by the properties of the colloids. Solvent-based polyacrylate adhesives and water-soluble polyacrylate adhesives are commonly used, and they have different characteristics.
