ABOUT CORECHEM

Corechem is a brand of Guangdong Core New Materials Co., Ltd., a high-tech enterprise integrating R&D, manufacturing, sales, and application services. The company has also been recognized as a Specialized and Innovative Enterprise and a Hidden Champion Enterprise in Guangdong Province.

Since our founding in 2008, we have focused on industrial additives and interfacial control technologies. To address critical challenges in the wetting, dispersion, stabilization, anti-settling, rheology, and defoaming of pigments, powders, and nanomaterials in liquid systems, we have independently developed polymeric dispersants, polyamide thixotropic agents, fluorosilicone polymers, wetting and leveling agents, defoamers, anti-skinning agents, and other functional additives.

Our products are widely used in industrial coatings, printing inks and digital inkjet, adhesives and sealants, waterproofing materials, agrochemical formulations, nanomaterial slurries, electronic materials, and new energy materials. We provide customers with end-to-end solutions covering product selection, formulation optimization, laboratory validation, and industrial-scale application.

Corechem operates an automated production base with an annual capacity of 10,000 metric tons in the national-level chemical industrial park in Longnan, Jiangxi. We also operate an integrated R&D and office center of approximately 1,500 square meters in Zhongxin, Zengcheng, Guangzhou, with four laboratories dedicated to material applications, innovative synthesis, precision testing, and digital inkjet. We continue to commercialize technologies in polymer synthesis, polyamide rheology control, and functional fluorosilicone polymers, supported by multiple granted patents in China and overseas.

Over the years, Corechem has supplied products and technical services to industry-leading companies including Sherwin-Williams, AkzoNobel, Sika, Oriental Yuhong, Keshun, Jointas, Bauhinia Inks, and Kingswood.

We believe truly competitive chemical products come not only from the laboratory, but also from a deep understanding of customer applications. We welcome people who are passionate about chemistry and committed to the industry for the long term. Together, we will solve real formulation and materials challenges and help advance high-performance industrial additives from China.
