Import Dcoit-30 — Buy in Bulk from Supplier in China

DCOIT-30 is a light-yellow transparent liquid biocide identified by CAS 64359-81-5. The product contains a maximum of 30.0% active substance as stated in the supplier data. It is supplied in 180 kg steel drums and is described as suitable for marine paint applications. The material is soluble in oil-based paints but exhibits low water solubility, giving it lasting antimicrobial effect.

DCOIT belongs to the isothiazolinone class of broad-spectrum biocides commonly formulated at 20-35% active content for liquid paint systems (typical). Its thermal stability allows incorporation at any production step without degradation. Compatibility with a range of resin binders makes it a standard choice for preventing bacterial and fungal growth in marine environments. The low water solubility reduces leaching, a characteristic noted across commercial DCOIT products (typical).

For marine paints the recommended dosing is 5-15% w/w, providing protection against organisms such as Penicillium notatum and Aspergillus niger. Users must wear protective clothing, goggles and rubber gloves, and cleanse any skin or eye contact immediately. The product has a one-year shelf life when stored at ambient temperature in a dark, airtight, moisture-proof location. Importers should confirm packaging integrity, safety data sheet and active-content certification with the supplier before finalising bulk orders.
