Abstract

The strength of adhesive bonds is generally assumed to be highly dependent on the quality of workmanship. This fact makes controlling bodies hesitant to allow adhesive bonding connections in structural (glass) engineering. However, little is known quantitatively about the sensitivity of adhesive bond strength to sub-standard workmanship. Therefore, the influence of building-site related contaminations of the bond strength of three different two-component epoxies was experimentally investigated. It is demonstrated that the sensitivity to contaminations varies widely even between rather similar adhesives. Importantly, at least one adhesive actually seems to be rather resistant to most tested contaminations. Consequently, such robust products may be particularly suitable for application in the building industry. However, further research on the durability of contaminated bonds is required.
