SURFACE QUALITY COMPARISON BETWEEN TRADITIONAL AND ONE STEP PRODUCTION CYCLE

Abstract

Surface quality behaviour was investigated for one step production system compared to traditional painting process. This study was conducted to compare and analyse the effect of one step production cycle on surface quality when compared with traditional production system. Sample plates were prepared by traditional painting process with acrylic solvent based paint and one step production cycle with polyurethane (PU) coating systems. Surface quality of plates were analysed regarding scratch resistance, thermal aging resistance and orange peeling formation. Test methods were determined according to Fiat painted plastic part qualification norms. Test results revealed that gloss loss, roughness values and orange peeling formation affinity were less for one step production system with PU than conventional system with solvent based acrylic paint. This study contributes to revealing surface quality performance for the methods of producing painted parts that are more resistant to scratch, thermal conditions and having much fewer surface defects like orange peeling.
