The effects of hydroxy acrylic resin, ketone-aldehyde resin, curing agent, leveling agent and baking condition on the adhesion of coatings in a coating accessory system for motorcycle fuel tank were discussed. It was found that a good-performance coating accessory system with an interlayer adhesion strength of 0 grade, flexibility of 1 mm, impact strength of 50 kg·cm and pencil hardness of 2H for motorcycle fuel tank can be obtained by using hydroxy acrylic resin in combination with ketone-aldehyde resin with HDI trimer as curing agent and polyacrylate solution as leveling agent after baking at 90 ℃ for 30 min or at 120 ℃ for 20 min.
