Product Description


DCOIT 99% (C11H17Cl2NOS)
Biocide for Silicone Sealants
Synonym: DCOIT,4.5-Dichloro-2-n-octyl-4-isothiazolin-3-one, dichloroctylisothiazolinone
DCOIT-99 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 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.
