The discoloration and discoloration of aluminum composite panels are mainly caused by improper selection of panels. Aluminum-plastic panels are divided into indoor panels and outdoor panels. The surface coatings of the two panels are different, which determines their application in different occasions. The surface of the board used indoors is generally sprayed with a resin coating. This coating cannot adapt to the harsh outdoor natural environment. If it is used outdoors, it will naturally accelerate its aging process, causing discoloration and discoloration.
The surface coating of outdoor aluminum-plastic panels is generally made of polyfluorocarbon resin coating with strong anti-aging and anti-ultraviolet ability, which is expensive. Some construction units deceived the owners, pretending to be anti-aging and anti-corrosion high-quality fluorocarbon sheets for indoor use, to squeeze unreasonable profits, thus causing serious discoloration and discoloration of the aluminum sheets used in the project. The glue opening and falling off of the aluminum composite panel are mainly caused by the improper selection of the binder.
As an ideal binder for outdoor aluminum composite panel projects, silicone adhesive has unique advantages. In the past, my country's silicone rubber mainly relied on imports, and its value was prohibitive for many people.
