Abstract

Comparative data on characteristics of the adhesive joints executed by epoxy adhesive of cold curing VK-9 (not modified) and VK-27 (modified by rubber) are provided. It is shown that updating of epoxy adhesive of cold curing by rubber leads to increase of strength, deformation and resource characteristics of glued joints, however heat resistance of adhesive joints decreases. Comparison of properties of the adhesive joints executed by adhesives VK-9 and VK-27 is given, at influence of loadings, temperatures, humidity and other factors.
