Import Dps Contract Wuhan Excellent Voyage — Buy in Bulk from Supplier in China

Dps Contract is the trade name for n,n-dimethyl-dithiocarbamylpropyl sulfonic acid, sodium salt, with CAS number 18880-36-9 and molecular formula C6H12NaO3S3. The product arrives as a white to yellowish powder with an assay of 98%, indicating high chemical purity. It is not a mixture or blend but a single compound manufactured under controlled conditions for consistent performance in electroplating baths.

This compound functions as a brightening agent in acid copper electroplating when used alongside polyether additives and wetting agents. It promotes a smooth, ductile copper deposit by modifying the crystal growth rate at the cathode surface. Typical industry standards for such additives require purity above 97% to avoid contamination of the plating solution. The yellowish tint in some batches is normal and does not affect functionality if assay levels meet specification.

Buyers in the printed circuit board, automotive, and electronics manufacturing sectors use Dps Contract to achieve quality copper finishes. It is supplied in 25kg polyethylene-lined cartons, with typical minimum order quantities starting at 100kg. Lead times are generally 7 to 14 days from Wuhan, depending on inventory. Incoterms are typically FOB Shanghai or CIF, with payment via T/T or L/C. Buyers should confirm compatibility with their existing plating bath chemistry before scale-up.
