Abstract
Official abstract text for this publication.
A first aspect of the present invention is an adhesive composition comprising one or more polyisocyanates and one or more phosphate-functional polyols. A second aspect of the present invention is a method of bonding two substrates together to form a bonded article, said method comprising the steps of applying a layer of the composition of the first aspect to one of said substrates, contacting said layer of the composition of claim 1 to a second substrate, and curing or allowing to cure the composition of claim 1 . A third aspect of the present invention is a bonded article formed by the method of the second aspect.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adhesive composition comprising one or more polyisocyanates and one or more phosphate-functional polyols, wherein said one or more phosphate-functional polyols is a phosphate ester of a precursor polyol. 2. The adhesive composition of claim 1 , wherein said precursor polyol is either an alkyl triol or alkoxylated alkyl triol. 3. The adhesive composition of claim 1 , wherein said precursor polyol is either glycerol or alkoxylated glycerol. 4. The adhesive composition of claim 1 , wherein said precursor polyol is a propoxylated glycerol. 5. A method of bonding two substrates together to form a bonded article, said method comprising the steps of applying a layer of the adhesive composition of claim 1 to one of said substrates, contacting said layer of the adhesive composition of claim 1 to a second substrate, and curing or allowing to cure the adhesive composition of claim 1 . 6. A bonded article formed by the method of claim 5 . 7. The bonded article of claim 6 , wherein said bonded article is a laminate.
