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.

Before placing an order for DCOIT-30, importers should request the latest Certificate of Analysis and Material Safety Data Sheet to confirm the 30% active content and appearance specifications. Verify that the 180 kg drum packaging meets your handling capabilities and that the product has been stored in a dark, airtight environment to preserve its shelf life. Clarify any required regulatory approvals for biocidal chemicals in the destination market.
Logistical details such as the preferred Incoterm, shipping method and freight forwarder must be agreed with the supplier, as the listing does not specify these terms. The one-year shelf life allows flexible scheduling, but buyers should confirm the expected dispatch window to avoid storage delays. Typical payment arrangements for bulk chemicals include a letter of credit or advance payment, but exact conditions should be negotiated directly.
To ensure product quality, arrange an independent laboratory test for active-substance concentration upon receipt of the shipment. Third-party inspection can verify drum integrity and confirm that the liquid remains clear and free of contamination. Retain all certificates, test reports and customs documentation, as they are essential for regulatory compliance and future import records.
