Since different applications have different requirements for pigments, we accordingly developed diverse testing methods. Besides general test methods, we apply advanced test equipment such as infra-red spectrophotometer and X-rite color difference meter to control DL, DA, DB, DC, DH, DE values and tinctorial strength of each lot made to the party against standard approved by the party, which has met international common standards.

The pigments have steady physical and chemical character, especially the pigment of iron oxide, it is very stability to alkaline. Such as cement and lime. It's soda-resisting, acid resisting and heat resisting. The color can not be changed under the relative temperature and by shine upon strongly. It has no effection o the cement and has no effection to its strength and to rubber products' vulcanization.

Our products are widely used in surface polishing agent for rubber, paint, printingink, glass, color cement, paves, brick and colored industrial construction materials. We have customers convering Europe, U.S.AS, Japan, Korea, HongKong, Africa and Southeast Asia area. We will supply you the quality goods with very competitive price and perfect service.

To improve the quality of our products to satisfy clients' requirements. The factory setting up the quality control system according to ISO9002. Moreover, we control the quality use MINOTA-CM3600d from Japan and we are going to import a set of mixture machine equipment and a set of advanced test facilities. We look forward to cooperate with friends at home and abroad based on equality and mutual benefits.
