Atmospheric corrosion behavior of paint systems applied on weathered hot-dip galvanized steel Article uri icon

abstract

  • The durability of a paint coating applied on a galvanized steel surface which has been exposed for a certain time to the atmosphere depends on the aggressiveness of the atmosphere, the preparation of the weathered surface prior to painting, and the type of coating applied. This work presents the results of an atmospheric corrosion study carried out over 11 years in three Spanish atmospheres of highly different degrees of aggressiveness (Madrid, Bilbao, and Tenerife), applying eight paint coatings on galvanized steel weathered in different conditions and using different methods to prepare the aged metallic surface prior to painting.
