Highly effective and environmentally sound microbicides


KATHON™ 287 PXE Microbicide 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 including Aspergillus, Alternaria and Candida species. Due to the very low solubility of DCOIT, the leaching from silicone sealants is minimal, and long term protection is provided.

Used In:
