AN INVESTIGATION INTO DURABILITY CHARACTERISTICS OF MARINE PAINTS APPLIED ON SURFACES TREATED IN VARIOUS WAYS
The most important factors affecting the overall performance of marine paints are the coating method employed and the surface preparation carried out before application. Tests were carried out to investigate the relationship between the grade of surface cleaning and durability of the paint film. Four types of test were used: (1) Impedance--measured with specially designed equipment capable of estimating durability of the paint film, ignoring damaged spots. Measurements were made after immersion of the specimen in sea water for 7 to 60 days. (2) Water absorption (Gravimetric Method)--this showed that film thickness affected water absorption of the epoxy paint rather than surface preparation. (3) Impact abrasion--data on the relationship between surface preparation and durability of the paint film were obtained. (4) Adhesion--measured quantitatively with an adhesion tester. Surface preparation was shown to have an effect on pure epoxy paint, but their was peeling of the binding agent with tar epoxy and peeling between the paint layers with chlorinated rubber paint.
