Hardeners based on cycloaliphatic amines adducted with epoxy oligomers have been developed. The structure and physical properties of the hardeners were studied in comparison with standards. The physico-mechanical properties and cure rate of epoxy coatings using synthesized hardeners were analyzed.

The analysis of the influence of pigments on the coating for corrosion protection of oil and gas pipelines has been carried out. Technical descriptions and test results of coatings on soot and black iron oxide pigment under the influence of a magnetic field are presented.

The article draws attention to the fact that despite the successful combination of properties such as the ability to provide long-term protection of ferrous metals from corrosion, unpretentiousness in technology (they can be applied to wet and even corroded products), accessibility, relative cheapness, film-forming inhibited petroleum compounds (PINS) are still used on a scale far from justified. In this article, the authors are trying to draw decent attention to them.

The paper shows the influence of the molecular weight of epoxy resins on the characteristics of the conditional viscosity of their solutions in organic solvents in order to optimize the formulation of epoxy paint and varnish materials. In the course of the work a number of epoxy oligomers with different molecular weights from different manufacturers, as well as solvents for the preparation of resin solutions were selected. The results of the work are viscosity curves of the studied solutions, calculation of technological points, construction of graphical dependences of solution properties on molecular weights of the considered oligomers.

The work is devoted to the development of formulations of removable inter-operating industrial paint and varnish materials. The influence of various pigments and additives on the properties of materials and coatings based on them is shown. The coatings have the necessary removability and meet the requirements for these types of paintwork coatings.

The analysis of the achievements of the world's leading companies in the field of creating materials and technologies for the production of paint coatings formed using UV/LED/EB curing to protect metal substrates is carried out.

The article discusses the properties of the vibration-absorbing coating when a standard solvent is added to it. A method for determining possible ways of introducing an abnormal solvent into the coating and a method for quantifying the content of volatile substances in the coating are described. The effects of adding an abnormal solvent during the preparation of the coating on the content of volatile substances in the cured coating have been determined.
