1. Under normal circumstances, the color-coated board can be selected according to the standard color of the manufacturer, which can shorten the workload in the early stage of production. If a special color is required, the paint can be produced only when the paint is first configured as a small sample in the paint factory, and the various properties meet the requirements, so the production time from order to color-coated plate will be longer.
2. The surface gloss of the coating measured by the reflection angle of 60 degrees, the larger the value, the higher the gloss, and the light and matt coatings used in construction are between 30-55. This is because high-gloss coatings are used in buildings to reflect strong and dazzling sunlight; if indoors, it is easy to cause visual fatigue under the light at night.
3. The coating film of the color-coated board is made of baking synthetic resin coating. When used outdoors, the coating film will gradually deteriorate due to the influence of sunlight, temperature and rain. Carefully observe the surface of the steel plate, or gently touch it with your fingers. , you can find the existence of white powder. This phenomenon is the chalking of the coating film, which is unavoidable.
4. Different types of coatings should be used for color-coated boards, which can delay the age of chalking. In addition, the service life is different in different regions such as coastal areas, industrial areas and rural areas. In the event of corrosion such as chalking and cracking of the coating film, repainting should be carried out to prolong the service life.
