The characterization of zinc plated surface after aged adhesives

Abstract

The use of adhesive bonding rather than mechanical fasteners offers the potential for reduced weight and cost.This paper aims to make characterization of zinc plated surface and aged adhesives (in water at 50 °C. Surface analysis related to zinc plated surface and adhesives were carried out by using analytical scanning electron microscopy (SEM) with energy dispersive X-ray (EDX). Acoording to SEM results related to corrosion resistance which are adhesive types, Polyurethane was good, Sikasil SG20 was medium level compared to others, Sikaflex®-552 was very low corrosion resistance. As seen that in the peeling test, Polyurethane was the worst whereas SikasilSG-20 was the best. However, Sikasil® SG20 adhesive would be good choose compared to others, in case of this type of adhesion should improve the feature of corrosion resistant on zinc plated steel surfaces.
