COMPOSIÇÃO AQUOSA PARA MEIOS DE FILTRO COM RESISTÊNCIA APERFEIÇOADA AO ROMPIMENTO A ÚMIDO

摘要

The invention relates to an aqueous composition including an aqueous silane functional polymer and a polyamide epichlorohydrin adduct. The aqueous silane functional polymer includes a reaction product of at least one first ethylenically unsaturated monomer that is free of oxysilane functional groups, and at least one second ethylenically unsaturated monomer that includes an oxysilane functional group. The aqueous composition is useful for treating cellulosic materials for filter media.
