Abstract: DCOIT-10 (4,5-Dichloro-2-octyl-isothiazolone, CAS: 64359-81-5) is a kind of high efficiency, broad spectrum and environmental protection anti-mold antibacterial agent, which has a strong inhibitory effect on various molds, fungi and algae. DCOIT-10 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.
