Reduction of aesthetical properties of organic coatings caused by mechanical damage
چکیده انگلیسی

Organic coatings are the most commonly used system for protection from corrosion. In many applications, the protective properties against corrosion are associated with several other properties, including resistance to abrasion and good aesthetic appearance. This is particularly important for the automotive and transport industry, building trade, domestic products, packaging. To evaluate the abrasion resistance of organic coatings the Taber Abraser test is frequently used. The aim of this work is to evaluate the reduction of aesthetical properties, caused by abrasion by Taber test, using different abrasive pastes. The level of damage was evaluated through gloss measurements; 20° was the most sensitive angle to gloss changes, with this geometry different samples could be compared. The correlation between the changes of gloss and the damage was investigated using optical microscopy and environmental scanning electron microscopy. With increase of grain dimensions, the paste became more abrasive with negative effect on the aesthetical aspect of the organic coating.
