DADMAC
DADMAC, or dimethyl diallyl ammonium chloride, is a cationic polymer used primarily as a coagulant and flocculant in industrial water treatment. This product is supplied by Weifang Greatland Chemicals Co., Ltd. in liquid form with a concentration of 50% active ingredient, as stated in the source data. It appears as a clear, colourless solution with a pH range of 4.5 to 6.5 at 25°C, consistent with standard commercial grades. The molecular weight is not specified, but the chemical structure is confirmed as C8H16ClN.
The compound is typically produced via quaternization of diallylamine with methyl chloride, a standard industrial route. It is not a solid but a stable aqueous solution, which reduces handling risks compared to powder forms. Typical industry variants include concentrations from 30% to 60%, with 50% being the most common for municipal and industrial wastewater applications. No certifications such as ISO or SGS are confirmed in the source data, and claims about such certifications must be verified directly with the supplier.
DADMAC is used in papermaking to improve retention of fine particles, in textile processing to enhance fabric softness and dye uptake, and in oilfield applications to control clay swelling. Buyers include municipal water utilities, paper mills, and chemical processors in Asia, Europe, and North America. Packaging is in 200L plastic drums or IBC totes, though exact packaging details are not confirmed. Trade terms such as MOQ, Incoterms, or lead time are not provided and must be requested directly from the supplier.

Sourcing DADMAC from Weifang Greatland Chemicals Co., Ltd. - China Import Guide
Before ordering DADMAC from Weifang Greatland Chemicals Co., Ltd., verify the active concentration by requesting a recent certificate of analysis with titration results. Confirm the solution is free of visible particles, sediment, or odour, which may indicate degradation. Do not accept generic 'high purity' claims without analytical data. Request the CAS number and molecular weight to ensure consistency with your process requirements.
Logistics are typically handled via sea freight in 200L drums or IBC totes. Lead time is not stated and must be confirmed with the supplier. Incoterms are not provided; buyers should negotiate FOB Qingdao or CIF destination. Payment terms are not disclosed - common options include LC at sight or 30% advance with balance against B/L.

For quality control, request a batch-specific certificate of analysis showing pH, active content, chloride levels, and viscosity. Inspect drums for leaks or bulging before unloading. Retain a sample from each batch for independent lab testing. Ensure the supplier provides SDS and transport documentation compliant with IMDG Code for Class 9 hazardous materials. Document all inspection results to support any claims for non-conformance.
