Pengaruh Proses Painting Dengan Coating Asphalt Enamel Terhadap Daya Rekat Cat Pada Material SS400

Abstract

The painting is process to protect object from rusting process. In the process, many factors that were ignored properly. These factor also determine the result, quality, and ability of paint to be sticked. Based on the problem above, this riset was made to study variations in surface preparation, applicator, and thickness to know the adhesion in SS400 . Factorial experiment is used based on factorial design in 27 trials. The test uses a pull of test approves the ASTM D4541 standard. The result factor effect is 7,97% for thickness, 32,91% for surface preparation, and 59,12% for applicator. The effect of thickness is less significant on adhesion while the surface preparation and applicator. Type of surface preparation and applicator have asignificant effect. Power tool, brush, and a thickness 225µ are optimal prameters for painting.
