Analiza otapalnih premaza sušenih infracrvenim zračenjem

Accelerated infrared (IR) drying of coatings is increasingly used in the industry. Drying is performed via IR emitters, powered by gas or electricity. The main advantage of using IR drying is drying time reduction and higher production rate. Another advantage is burning the harmful VOCs (Volatile organic compound) from the coatings, therefore the environmental impact of this drying method is very low. In this study, solvent-borne coating systems were applied and dried by infrared as well as in atmospheric conditions. Catalytic IR emitters were used for accelerated drying of the coatings. The purpose of the investigation was to show how much time can be saved by using IR technology and to compare the protective properties of differently dried coatings. After the coatings were cured, chambers for accelerated corrosion testing were used. The succeeding steps were the adhesion and the hardness measurements, which were evaluated using Pull-off and Pencil test. The results have shown the same or even better properties of IR- dried coatings, along with the significant drying time reduction. This study is part of the project “Smart plant for drying liquid coatings” (reference code: KK.01.2.1.02.0030) which is co-financed by the European Union from the European Regional Development Fund.
