URALANE 5776-A/B High Strength Urethane Adhesive
Uralane 5776-A/B is a two part urethane adhesive designed for bonding aluminum and plastic substrates. Uralane 5776-A/B develops high peel strength bonds on metals, phenolics, epoxies, polyesters and many thermoplastics. The semi-paste consistency handles and spreads easily. Long work life allows assembly of large parts. Bonded assemblies can be cured at room temperature in 5-7 days or accelerated with heat cure.
