Problems solved by technology
[0002] At present, the weather resistance of the glue products used in the solar energy industry is not good, resulting in the shortening of the service life of the solar energy products used outdoors, the deterioration of product quality, and the deterioration of the weather resistance of the products. The main reason is that the glue products produced by the current formula are not durable. Poor yellowing, poor UV resistance and aging performance, it is not easy to make products with high yellowing resistance, high weather resistance and products with good comprehensive performance
After the yellowing resistance is resolved, it will lead to a decline in adhesive performance, mechanical properties and other properties
