As we all know, food, medicines, etc. have shelf life, so whether the decoration materials such as paint also have a shelf life? In this regard, the Beijing Municipal Industry and Commerce Department suggested that consumers should pay attention to the effects of coatings when purchasing paints. The date of manufacture and shelf life on the outer packaging of the paint to prevent the purchase of products that have passed the expiration date or the expiration date.
According to the paint experts, the paint will add some mildew-proof materials during the production process. The addition of these materials will directly determine the shelf life of the paint. In general, coatings have a shelf life of 1 to 3 years. High-quality paint can enhance the taste of the whole room and give the family life a richer connotation. However, the use of paints that exceed the shelf life may not only affect the decorative effect, but may also pose hidden dangers for future life. In coatings that exceed the shelf life, the ingredients may change due to various factors, so that they do not achieve their intended function and function, and such deterioration is sometimes irreversible, even in the case of closed storage, the overall performance of the coating and Efficacy will also be affected. The coating itself is a mixture. If the shelf life is exceeded, the coating may have delamination, odor, agglomeration, etc., and the amount of bacteria contained in the coating will greatly exceed the normal level. If such an expired coating is used, many paint film defects will occur, such as the adhesion of the paint film is not strong, easy to fall off, cracking, and bubbles appear, which makes the performance and internal performance of the paint greatly reduced.
The summer sun is more abundant, and the paint can't be exposed to the sun for a long time, otherwise it will cause the paint to deteriorate.
