To provide a urethane adhesive composition capable of obtaining a composite material excellent in an adhesion property (property to be adhered) with an object to be adhered and also excellent in a heat insulation property, an application method for a urethane adhesive composition and a composite material.
The urethane adhesive composition comprises a base material component containing a urethane prepolymer (A), and a curing agent component containing a heating-curable type latent curing agent (B). The urethane prepolymer (A) has a structure that all isocyanate groups in the molecule are bonded to a secondary carbon or a tertiary carbon not containing an aromatic ring. An unfoamed heat foaming microcapsule (C) is contained in the base material component and/or the curing agent component.
