Study of polymer adhesion to steel

Abstract

Tests on the dependence of glues shear strength on: gluing temperature, keeping time before testing, cooling environment, surface roughness, surface conditions, temperature and time of drying on air and in drying oven were carried out to select proper thermoplastics to use as glues for connection of steel elements together. The highest shear strength was showed by the following materials: desmopan 150, antifriction polyamide PA 610-L-DM, impact-resistant glass-filled polyamide. Given results allow significantly expanding scope of application of polymers as gluing compositions.
