Abstract
The present invention relates to a composition comprising: a) one or more organometallic compounds; b) one or more high boiling point solvents; and c) one or more low boiling point solvents. The invention further relates to a system comprising a) one or more organometallic compounds; b) one or more high boiling point solvents; and c) one or more low boiling point solvents and an isocyanate functional adhesive. The isocyanate functional adhesive may be a one part or a two part adhesive. The invention further relates to methods of bonding substrates together using the compositions of the invention.
Claims20
A composition for improving the adhesion of an isocyanate functional adhesive to a substrate including a fiber reinforced plastic, the composition comprising:
- a) 0.1 to about 5.0 weight percent of one or more organometallic compounds including one or more metals and a ligand, wherein the ligand includes an alkyl group, an ester, a carboxylic acid, an ether, a mercaptide, or any combination thereof, with the proviso that the organometallic compound including the carboxylic acid is a dialkyl metal carboxylate;
- b) one or more high boiling point solvents;
- and
- c) one or more low boiling point solvents selected from cycloaliphatic hydrocarbons, aliphatic hydrocarbons, aromatic hydrocarbons, ketones, and esters;
- wherein the composition does not contain a film forming resin;
- and the composition is a stable solution or dispersion of the one or more organometallic compounds in the solvents.
