Import Bit 85 Powder/ 1 2 Benzisothiazolin 3 One — Buy in wholesale FOB from Supplier in China

BIT-85 from Sinotrust International Trade Co Ltd is a powdered biocide based on 1,2-benzisothiazolin-3-one (BIT), supplied from Dalian, Liaoning Province, China. The active ingredient carries CAS number 2634-33-5 with an EINECS listing of 220-120-9, and the material presents as a white powder with a minimum active substance content of 99% and a dryness specification of 85%. Its molecular formula is C7H4NOS with a molecular weight of 151.18, and it is formulated specifically for in-can preservation of water-based paints, adhesives, polymer emulsions, and related industrial products. The powder exhibits a flash point of 77.5 degrees Celsius and a density of 1.367 g per cubic centimetre at 25 degrees Celsius, with water content capped at 15% maximum.

The biocide operates through a non-specific mode of action that reduces microbial resistance potential, delivering broad-spectrum antimicrobial control against bacteria, yeast, and fungi in high pH systems. It remains stable in the presence of amines and shows good compatibility with most aqueous compositions, including latex products, water-soluble resins, acrylics, polyurethanes, and emulsified oil preparations. The active ingredient is non-volatile and possesses comparatively high heat stability, allowing incorporation into fluids that are still hot during processing. Standard industrial packaging includes 25kg fiber drums and multi-weight bags from 25kg up to 750kg with pallet, reflecting typical bulk chemical distribution formats for specialty preservative additives.

Buyers of this grade are typically industrial chemical distributors, paint and coating manufacturers, adhesive formulators, and polymer emulsion producers seeking shelf-life protection during storage. The product finds application across waterborne coatings, coated paper production, oilfield water treatment systems, and oil extraction operations where microbial contamination control is critical. For trade terms, buyers should confirm minimum order quantities, lead times, Incoterms, and current pricing directly with Sinotrust International Trade Co Ltd, as these are not specified in the listing. Storage requires room temperature conditions in a dark, air-tight, and moisture-proof environment with a stated shelf life of one year.

Sinotrust International Trade Co Ltd is located in Zhongshan District, Dalian, Liaoning Province, China, with the postal code 257000. The company holds a harbor trust tier on the platform, though it currently shows a response rate of 0.00% with average response hours recorded at zero. This profile suggests limited or no engagement history through the platform's messaging system, so buyers should expect to establish direct contact outside the platform interface to assess responsiveness and communication practices.

The listing presents itself as an industrial chemical supplier focused on specialty biocide additives, specifically the BIT-85 preservation grade for formulated water-based products. No verified certifications, manufacturing accreditations, or specific export licences are stated in the available profile data. Buyers should request proof of manufacturing capability, quality management systems, and any REACH or EPA registrations relevant to their import jurisdiction before committing to an order.
