ALDEHYDE SCRUBBING THROUGH APPLICATION OF AQUEOUS FLASH COATING COMPOSITION TO CRUST LEATHER AND TANNED LEATHER

摘要

PURPOSE: An aqueous flash coating composition is provided to effectively remove aldehyde from leather or crust using aqueous acid functional acrylic polymer with no a material converted into aldehyde or formaldehyde.;CONSTITUTION: An aqueous flash coating composition comprises one or more acid functional copolymer binders; and 0.03-1.0 equivalent or less of active compound based on the total equivalent number of carboxylic acids among the acid functional copolymer binders. The acid functional copolymer binder is obtained by copolymerizing 50-90 weight% one or more hydrophobic comonomer and 10-50 weight% one or more copolymerizable hydrophilic acidic comonomer.;COPYRIGHT KIPO 2010
