The corrosion behavior of primid-curing solidified polyester powder coating defects in marine environment was investigated by CASS test. immersion test. electrochemical impedance spectroscopy (EIS) and scanning Kelvin probe (SKP). The results show that the primid-curing polyester powder coating has a small amount of blisters along the scratch edge. https://www.houseandholders.shop/product-category/paper-towel-holder/
