Principle 3
Abrasive type or self-polishing antifouling coating sample preparation in the test model, then the model is mounted on a rotary analog device submerged in water
, The abrasion test at a constant speed. After a certain interval of time, remove the test panel, the thickness change before and after abrasion test antifouling coat,
Antifouling coatings abrasion rate calculated based on erosion of time.
