This baking and curing primer with special media resistance is a kind of coating A component,which is made of epoxy E-20 resin,epoxy 828 resin and reactive diluent-polypropylene glycol diglycidyl ether(D-1217),mixing with color fillers and additives.By adding curing agent,the primer with a high solid content was prepared finally,which can be cured at room temperature and be baking cured.It effectively improves the mechanical properties of the coating and the resistance to special media.Through the screening experiment of coating base material matching,reactive diluent,curing agent,amount of plasticizer,ratio of pigment to base,curing temperature,its impact on the performance of anticorrosive coatings is discussed,and the final formula is determined.
