protection, one protective zinc layer repairing paint was studied. The influence of the components (compound zinc powder and organic-inorganic hybrid modifier) on coating performance was analyzed and compared. The results indicate that the coating adhesion increases with increasing the content of compound zinc powder at the pigment/binder mass ratio of 4:1, and the organic-inorganic hybrid modifier......
