Paint chemicals

Formulated based on the needs and usages of our customers, our phenolic molding compounds are produced by mixing different materials and pigments to the base phenolic resin which we also manufacture. Employing integrated operations (from raw materials introduction, reaction process, to final packaging), our products are manufactured with the strictest quality management. As result, our phenolic molding compounds offer consistent quality and good performance, and they have gained recognition from all sectors over the years.
