Product Overview:

4,5-Dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) is a broad-spectrum antimicrobial compound known for its exceptional antifouling and biocidal properties. It is widely used to control bacteria, algae, fungi, and marine organisms across a range of industrial and marine applications. DCOIT provides long-lasting protection, making it ideal for environments exposed to high humidity, moisture, or marine conditions.

Thanks to its low water solubility and excellent environmental stability, DCOIT offers an effective solution for biofouling prevention in coatings, plastics, sealants, and marine paints—while minimizing leaching into aquatic systems.

Key Features & Benefits:

• ✅ Broad-spectrum efficacy against bacteria, fungi, algae, and marine fouling organisms

• 🌊 Ideal for antifouling coatings in marine vessels and submerged structures

• 🧪 Chemically stable in paints, coatings, and polymer systems

• 🔒 Low leaching rate ensures prolonged protection and environmental safety

• 🌿 Biodegradable breakdown products make it more eco-conscious

• ⚙️ Compatible with a wide range of industrial materials and formulations

Applications:

• Marine Coatings: Antifouling agent in paints for ships, boats, and offshore platforms

• Industrial Coatings: Preservation of paints, varnishes, and construction coatings

• Plastics & Polymers: Incorporated into PVC, polyurethane, and other resin-based materials

• Wood Protection: Inhibits microbial decay in treated wood products

• Adhesives & Sealants: Prevents microbial spoilage and extends shelf life

• Cooling Water Systems: Used in controlled concentrations for microbial control

Recommended Dosage:

Actual usage levels should be optimized based on formulation and efficacy testing.

Mode of Action:

DCOIT functions by disrupting microbial cell membrane function, interfering with essential enzymes and respiration processes. It effectively halts microbial colonization and biofilm formation, providing prolonged surface protection.

• Chemical Group: Isothiazolinones

• Function: Biocide / Antifouling / Preservative

Environmental & Safety Profile:

• ♻️ Low bioaccumulation potential
