Abstract

Dammar, a local plant resin (Dipterocaupacea sp) has been used in coating formulation to produce dammar-modified silicone resin. Dammar and silicone were mixed in various compositions and then were coated onto Aluminum Q-panel by using spin coating method and left to dry by using thermal process. Adhesion property was investigated by using cross hatch test.There were no significant damage and delaminations were observed at the panel coated with 10 wt.% of dammar that has undergone the cross-hatch test. Hence, the addition of more than 10 wt.% of dammar resulted in large delaminations and cracks on the coating materials. Contact angle measurement of wettability test was also being carried out.The surface coated with dammar-silicone resin was found to be hydrophobic where the contact angle obtained was 70° for the sample containing 10wt% of dammar. Electrochemical impedance spectroscopy (EIS) was successfully applied to study about the corrosion system and has been proven to be a powerful and accurate method for measuring corrosion rates of the coated materials.lt shown that (10wt.% dammar cured at 80°C) have higher coating resistivity and low conductivity.
