DCOIT 4.0% Email:sales@ozziechemical.com
Biocide for Silicone Sealants
Description
DCOIT-4.0 biocide has been specifically designed to meet the requirements for use in acetoxy silicone sealants, shows excellent efficacy against fungi and bacteria under the standard ISO 846 method B test conditions including Aspergillus, Alternaria and Candida species and accelerated leaching. Due to the very low solubility of DCOIT, the leaching from silicone sealants is minimal and long term protection is provided.
Broad spectrum efficacy, low leaching and rapid degradation of the very low concentrations of the active ingredient released into the environment during performance and easy incorporation into the sealant render this product aunique solution for the fungicidal protection of silicone sealants. DCOIT-4.0 does not contain any metals or arsenic compounds. As part of Ozzie' commitment to Responsible Care, extensive toxicological studies have been performed, showing that the active ingredient is non-mutagenic and non-teratogenic.

Directions for Use
DCOIT-4.0 biocide is a liquid product and is dosed either using automated metering systems or by hand-weighing. To ensure adequate mixing add the biocide at the compounding stage of the silicone sealant.
DCOIT-4.0 should be dosed in the range of 2.5kg - 25kg as supplied for a one tonne batch, which is equivalent to 250 ppm to 2500ppm active ingredient.
Basic Toxicological Information
LD 50 (rat, oral): 2600 mg/kg (female); 4400 mg/kg (male).
Handling and Storage
Please refer to the safety data sheet for further detail on this product and for precise handling instructions.
DCOIT-4.0 can easily be incorporated into the sealant at the compounding stage. Due to the biocidal nature of the product, protective clothing is to be worn while handling the product. Any handling or use that could create aerosols is to be avoided.
The processing and use of industrial chemicals require adequate technical and professional knowledge.
In general, avoid eye and skin contact, wear safety goggles, gloves and protective clothing. In case of eye or skin contact despite precautionary measures, wash immediately and thoroughly with plenty of warm water and obtain medical attention.
Packing
