In the early stage, we first focus on the customer's needs. The technical department communicates with customers to understand their application systems and technical requirements, and helps customers choose the right product models. The company provides free samples for customers to try. After the small test is passed, the sales department discusses the subsequent supply issues with customers.

If the existing products cannot meet customer needs, we can also develop related hyperdispersant products according to customer requirements. R&D expenses and intellectual property issues are determined by negotiation between the two parties.
