United Airlines Bonds Torlon Inserts in Aircraft Floor Panels With Polyurethane Adhesive
According to Rudy Sylvester, staff specialist engineer, Component Engineering -- Interiors at United’s San Francisco maintenance facility, “Our tests indicated that the Uralane polyurethane performed better than epoxy in both bolt pull-out strength and lap shear.” Uralane 5774-A/B is a tough, impact-resistant, semi-paste adhesive that is formulated for bonding engineering thermoplastics.
“The polyurethane flows neatly and easily from the dispensing cartridge, forming a smooth bead around the holes in the panel,” Sylvester explains. “It provides us with the dependable performance we need,” he concludes.
