  • Polyurethane bonding process for fuel bladders
    Patent number: 10723083
    Abstract: A method of bonding a metal fitting to a polyurethane structure, the method comprising abrading a surface of the metal fitting with an abrasive; cleaning the metal fitting with a solvent; cleaning a surface of the polyurethane structure with an alcohol; applying a primer to the surface of the metal fitting; applying an adhesive to the surface of the metal fitting and the surface of the polyurethane structure; applying a liquid polyurethane compound to the surface of the metal fitting and the surface of the polyurethane structure; and pressing the surface of the metal fitting against the surface of the polyurethane structure to form an assembly. The primer can comprise a first resin and a first catalyst in a ratio of about 1.1 to 1; the adhesive can comprise a second resin and a second catalyst in a ratio of about 3 to 1; and the liquid polyurethane compound can comprise a third resin and a third catalyst in a ratio of about 10 to 1.
