High-Efficiency Adhesive Compounds for Nonmetallic Surfaces

摘要

Based on the principles of the formation of adhesion contacts with different (including inert) sur-faces, a number of physicochemical procedures for an increase in the strength of adhesive joints is developed.These principles are elaborated at the Institute of Macromolecular Chemistry, National Academy of Sciencesof Ukraine. Basic models of the structure of adhesive ensuring the maximum value of adhesive strength are pro-posed. It is shown that synthesized epoxy–urethane oligomers ideally correspond to one of these models. Adhe-sive compositions are prepared on the basis of synthesized multifunctional oligomers and their physicochemicaland adhesion properties are studied. The high efficiency of these adhesives for bonding a wide spectrum ofmaterials including adherends with low surface energy is r6ealed. The set of the properties of developed adhe-sive compositions makes it possible to use them in the production of items designed for highly specialized pur-poses.
