[Problem] Polypropylene, polyethylene or EPDM Improvement of adhesion to polyolefin thermoplastic resin such as It provides a primer composition which guarantees simple production and good storage stability, while allowing good wetting with good homogeneous film properties with equal layer thickness. SOLUTION: This is a moisture-curable prepolymer containing at least hydrogenated polyisoprene-diol, and the terminal of the prepolymer contains an isocyanate group or a hydrolyzable silyl group. |
