Abstract
Official abstract text for this publication.
Water-based compositions that include a reaction product formed by reacting a polyol and an aminopolycarboxylic compound are discussed herein. The water-based compositions can include an isocyanate.
First claim
Opening claim text (preview).
What is claimed is: 1. A water-based composition comprising: a reaction product made by reacting a polyol and an aminopolycarboxylic compounds, wherein the aminopolycarboxylic compound is an ethylenediaminetetraacetic compound and the reaction product has from 0.03 to 2 weight percent of units derived from the aminopolycarboxylic compound based upon a total weight of the reaction product; an isocyanate; and water. 2. The water-based composition of claim 1 , wherein the aminopolycarboxylic compound is selected from ethylenediaminetetraacetic anhydride, ethylenediaminetetraacetic acid, and combinations thereof. 3. The water-based composition of claim 1 , wherein the polyol has a weight average molecular weight from 300 to 12,000 g/mol. 4. The water-based composition of claim 1 , wherein the water-based composition has an isocyanate index in a range from 1.0 to 1.6. 5. The water-based composition of claim 1 , wherein the water is from 10 weight percent to 80 weight percent of the water-based composition based upon a total weight of the reaction product, the isocyanate, and the water. 6. A laminate formed from the water-based composition of claim 1 . 7. The water-based composition of claim 1 , wherein the reaction product has an acid value of less than 5.
