Abstract
Official abstract text for this publication.
Embodiments of the present disclosure are directed towards solvent-based compositions that include a reaction product formed by reacting a polyol and an aminopolycarboxylic compound.
First claim
Opening claim text (preview).
What is claimed is: 1. A solvent-based composition comprising: a reaction product made by reacting a polyol and an aminopolycarboxylic compound, wherein the reaction product has from 0.03 to 10.0 weight percent of units derived from the aminopolycarboxylic compound based upon a total weight of the reaction product; an isocyanate; and a solvent. 2. The solvent-based composition of claim 1 , wherein the aminopolycarboxylic compound is an ethylenediaminetetraacetic compound. 3. The solvent-based composition of claim 1 , wherein the aminopolycarboxylic compound is selected from ethylenediaminetetraacetic anhydride, ethylenediaminetetraacetic acid, and combinations thereof. 4. The solvent-based composition of claim 1 , wherein the polyol has a weight average molecular weight from 300 to 12,000 g/mol. 5. The solvent-based composition of claim 1 , wherein the solvent-based composition has an isocyanate index in a range from 0.9 to 1.6. 6. The solvent-based composition of claim 1 , wherein the solvent is from 10 weight percent to 80 weight percent of the solvent-based composition based upon a total weight of the reaction product, the isocyanate, and the solvent. 7. A laminate formed from the solvent-based composition of claim 1 .
