DCOIT 10 Biocide for Silicone Sealants CAS 64359-81-5

Product Name: DCOIT-10

Chemical Name: 4.5-DICHLORO-2H-OCTYL-3(2H)-ISOTHIAZOLONE; 4,5-dichloro-2-n-octy-4-isothiazolin-3-one;

CAS No.: 64359-81-5

EINECS No.: 2648438

Molecular formula: C11H17NOSCl2

Molecular weight: 282.20

The active ingredient is: 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT)


It 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. It does not contain any metals or arsenic compounds.
