During the session ‘Protective coatings and corrosion inhibitors’ that was part of TOPICAL ISSUES OF CORROSION PROTECTION conference the participants talked about specifics of anti-corrosive coatings in the industry. Russian manufacturers did have something to tell about the related projects of their own.
This was the first session of the scientific-practical conference TOPICAL ISSUES OF CORROSION PROTECTION arranged during Corrosion Protection 2024 International Exhibition. Import substitution in this segment is gaining momentum, and the participants of the session were eager to talk about their achievements.
For instance, Vasily Bocharov, CEO at Zinker, made a report about the technology his company had designed – an alternative to hot galvanizing. The zinc coating resulting from application of Zinker composition contains 90+ percent of stabilized zinc. It protects iron or other metal electrochemically. According to Vasily Bocharov, after a one-hour-long treatment with this composition you can obtain a coating that will serve for up to 30 years.
Yuri Smolsky, Adviser to CEO at Technological Systems for Protective Coatings, spoke about other kinds of anti-corrosive coatings. The company produces metallized protective coatings, or MPCs. At first, MPCs appeared in the West and are currently widely applied in Japan, USA, Norway – including at offshore drilling rigs. In Russia, we also have positive experience of MPC use. For instance, the coating designed by Technological Systems for Protective Coatings has worked well at Astrakhan Gas Processing Plant. According to Yuri Smolsky, the key advantage of such MPCs is that they can be applied on components of any size. Moreover, they can be used both at production sites or in field conditions. After some research, Technological Systems for Protective Coatings signed an agreement with Gazprom, who required this coating for their drilling platform. According to the research results, this coating will be able to protect any structure from corrosion for a term of up to 37 seasons. ‘At the application level, our coating is slightly expensive than the zinc or paint one, but in the long run it offers certain benefits,’ Yuri Smolsky added.
Ilya Ivanov, Head of Electro-Chemical Protection Department at METACLAY, talked about the use of powdered polyethylene coatings. Kolchuga (Eng. chainmail) protective coating of his company’s design can protect pipes from both corrosion and physical impact. Mr. Ivanov outlined that most of underwater reducers are subject to physical damage and thus should be protected, too. Strategic partners of METACLAY company are Severstal and Volga Pipe Plant. In particular, the company’s protective coatings were used during construction of the second line of South Stream.
Territoriya is yet another company engaged into import substitution of anti-corrosion coatings. Head of Sales Andrey Zalepukhin mentioned that after Jotun and Henkel left Russia, his company started to produce protective coatings of their own. So far, their products have been put to use in the Moscow Metro and various metal works factories.
Maria Pyrova, Senior Technical Specialist at Russian Coatings, shared information about their experience of anti-corrosive painting materials production together with representatives of Pigment Holding.
