TLDR
In this article, a formaldehyde-free curable aqueous composition comprising a polyacid comprising at least two carboxylic acid groups, anhydride groups, or salts of the polyacid thereof is presented.Abstract:
A formaldehyde-free curable aqueous composition comprising: (a) a polyacid comprising at least two carboxylic acid groups, anhydride groups, or salts of the polyacid thereof; (b) an active hydrogen compound containing at least two active hydrogen groups selected from the group consisting of hydroxyl, primary amino, secondary amino, and mixtures thereof; and (c) a fluoroborate accelerator; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to about 1/3, and wherein said carboxylic acid groups, anhydride groups, or salts thereof are neutralized to an extent of less than 35% with a fixed base is disclosed. A method for curing formaldehyde-free polyacids and a method for bonding glass fiber heat-resistant nonwovens with a formaldehyde-free binder are further disclosed.read more
