Dear Valued Customers：

Due to the prolonged impact of rising raw material costs, the production costs of our products have been continuously increasing. In order to ensure the ongoing provision of high-quality products and services, the company has decided to increase the prices of all chemical agent products, including demolding agents, coarse aggregate agents, and repair agents, by 5% based on the previous prices. This decision will take effect from the 15th of this month. We sincerely apologize for any inconvenience this may cause and appreciate your understanding!
