Biocide for Silicone Sealants

Description

DCOIT-10 biocide has been specifically designed to meet the requirements for use in acetoxy silicone sealants, the active ingredient, 4.5-Dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT), 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-10 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.

Miscibility/Solubility

DCOIT-10 is miscible with a variety of non-polar solvents. DCOIT-10 is non-miscible with water. The solubility of the active ingredient in water is <10 ppm.

Directions for Use

DCOIT-10 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-10 should be dosed in the range of 1 kg - 10 kg as supplied for a one tonne batch, which is equivalent to 100 ppm to 1000 ppm active ingredient.
