Crosslinking in the base coat contributes to improved wet and dry abrasion resistance, Bally flexibility, and dryclean fastness. Finish extensibility is lowered with increasing crosslink density. The advantageous use of a reactive base coat under a high performance polyurethane top coat is illustrated. Note de contenu : - EXPERIMENTAL : - A. Formulations and finishing procedures - B.
