SUNCHEM supplies high-purity water treatment chemicals — scale & corrosion inhibitors, biocides, disinfectants, and coagulants — for industrial cooling towers, municipal water systems, swimming pools, and oil & gas applications.
The global water treatment chemicals market exceeds USD 35 billion and is driven by tightening environmental regulations, industrial expansion, and growing demand for clean water infrastructure across Asia, the Middle East, and Latin America.
SUNCHEM's portfolio covers the full treatment cycle — from coagulation and pH adjustment to scale inhibition, biocidal disinfection, and membrane protection — enabling clients to optimize water quality and system longevity.
Direct factory sourcing with full technical support and documentation for global compliance.
Every product ships with COA, SDS, and TDS on request. We support regulatory compliance for EU REACH, TSCA, and GHS globally.
All water treatment chemicals are tested to industrial-grade purity standards. Batch QC reports and third-party lab certificates available upon request.
From laboratory samples to multi-ton bulk shipments. We accommodate trial orders, regular purchase contracts, and emergency supply with fast turnaround.
Comprehensive coverage from scale inhibition to biocidal disinfection.
Phosphonate-based inhibitors (HEDP, ATMP, PBTCA) that prevent mineral scale deposition and metal corrosion in cooling and boiler systems.
Halogenated hydantoins (BCDMH, DCMEH, DCDMH), isocyanurate-based chlorine donors, and BIT for broad-spectrum microbial control in water systems and swimming pools.
Ferrous sulfate heptahydrate and related coagulants for municipal water clarification, sludge dewatering, and wastewater treatment to remove suspended solids.

SUNCHEM supplies a full range of water treatment chemicals including phosphonate-based scale and corrosion inhibitors (HEDP, ATMP, PBTCA), halogenated biocides (BCDMH, DCMEH, DCDMH), chlorine-based disinfectants (TCCA, SDIC), microbiocides (BIT), and coagulants such as ferrous sulfate heptahydrate. We carry 15 products in this category with more on request.
HEDP (1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) is a highly effective scale and corrosion inhibitor used in industrial cooling water systems, boilers, and heat exchangers. It chelates calcium and other metal ions to prevent mineral scale buildup and inhibits metal surface corrosion, extending equipment life and improving energy efficiency.
We offer a range of chlorine-releasing biocides including Trichloroisocyanuric Acid (TCCA, 90% available chlorine), Sodium Dichloroisocyanurate (SDIC, 56–60% available chlorine), Sodium Dichloroisocyanurate Dihydrate (SDD), Cyanuric Acid (chlorine stabilizer), BCDMH, DCMEH, and DCDMH. These are used in swimming pools, cooling towers, and industrial water disinfection.
Yes — all products have full technical documentation available including Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), and Technical Data Sheet (TDS). Documents can be provided in English and Chinese. Please email info@sunchemgroup.com with your product name and required document format.
Our minimum order quantities vary by product. Sample orders (500g–5kg) are available for qualification testing. Standard commercial orders typically start from 25kg to 1MT. For bulk quantities (drum, IBC, or flexi-bag), we offer competitive pricing with full export documentation. Contact us to discuss your specific volume requirements.
Yes, SUNCHEM exports to 45+ countries across Europe, North America, Southeast Asia, the Middle East, and Africa. We handle all export logistics including hazardous goods documentation (UN numbers, IMDG compliance), certificates of origin, and customs clearance support. Both air freight and sea freight are available.
Our company, in 2011, established the Water Treatment Agent Division, specializing in the export business of water treatment agents. More than 80% of the current water treatment agent production plants in China are small enterprises, most of which have no export business. The suppliers we cooperate with in Tianjin and Qingdao are all head enterprises in China and are familiar with export business.
We don't just provide you with raw materials. We recommend different agents and solutions depending on the application scenario. For example, for the oil project in Qatar, we provided a complete solution from the source water to all the final water treatment aspects.
