Description

Sodium N-(2-aminoethyl)aminoethanesulfonate is an aqueous solution of a sodium salt of an amino functional sulfonic acid. It contains a primary and a secondary amino group and combines the properties of an emulsifier and a chain extender in the production of aqueous PUR/water based polyurethane (WPU) dispersions.
