SURFACE QUALITY COMPARISON BETWEEN TRADITIONAL AND ONE STEP PRODUCTION CYCLE

Abstract

Surfacequality behaviour was investigated for one step production system compared totraditional painting process. This study was conducted to compare and analysethe effect of one step production cycle on surface quality when compared withtraditional production system. Sample plates were prepared by traditionalpainting process with acrylic solvent based paint and one step production cyclewith polyurethane (PU) coating systems. Surface quality of plates were analysedregarding scratch resistance, thermal aging resistance and orange peelingformation. Test methods were determined according to Fiat painted plastic partqualification norms. Test results revealed that gloss loss, roughness valuesand orange peeling formation affinity were less for one step production systemwith PU than conventional system with solvent based acrylic paint. This studycontributes to revealing surface quality performance for the methods ofproducing painted parts that are more resistant to scratch, thermal conditionsand having much fewer surface defects like orange peeling.
