Characteristics of the colloid of the aluminum profile protective tape Adhesion refers to the force required to peel the protective film from the surface to be attached after a period of time. The adhesion is related to the material to be applied, the pressure, the filming time, the angle at which the film is peeled off, and the temperature. According to the coating online, generally, as time and pressure rise, the adhesion will also rise, and the viscosity of the protective film cannot be increased too much to ensure no glue residue when tearing the film.
The 180 degree peel test is generally used to measure the adhesion. Cohesive force refers to the strength inside the colloid. As the protective film, the colloidal force must be very high. Otherwise, when the protective film is torn open, the inside of the colloid will crack and cause residual glue.
Cohesive force measurement method: The protective film is attached to the surface of the stainless steel, and a weight of a weight is suspended on the protective film to measure how much time the protective film needs to be pulled off by the weight. If the adhesion is greater than the cohesive force, the protective film is torn off, and the bond between the glue molecules will break to cause residual glue.
The adhesion of the aluminum profile protection tape refers to the bonding force between the gel and the film. If the adhesion is greater than the adhesion, the protective film is torn off, and the bond between the glue molecule and the film will break, resulting in residual glue. UV resistance Polyacrylate rubber is UV-resistant, transparent polyacrylate rubber protective film with UV stabilizer, its UV resistance can reach 3 ~ 6 months.
