About the technology

Zinc-rich coating is a method of application on a prepared surface of a special zinc composition containing active chemically pure zinc, polymer binders and volatile agents.

The resulting protective coating-zinc layer, contains 96% of the active stabilized zinc HZO SF* purity 99.995%, thus forming a stable galvanic pair Fe-Zn,in which zinc acts as an anode and protects the black metal (steel) electrochemical method, while providing maximum adhesion (1 point according to GOST 15140-78).

Distinctive features of the Zinc-rich coating

Forms a stable Zn-Fe subdispersion zone on the metal surface.
It has the property of interlayer diffusion.
Retains the function of surface self-preservation and self-healing throughout the service life.
It is characterized by sufficient resistance to abrasion.
The interatomic distance in the zinc layer is similar to the interatomic distance in the zinc layer, applied by the process of immersion in the bath.
It is applied even in winter at a temperature of -35°C.
UV-stable, has a noble gray color.

Difference from analogues

Zinc plating, unlike zinc-filled coatings (cold galvanizing), does not require overlapping finishing layers, thanks to a unique patented polymer that provides cathodic protection of zinc throughout its life. It is used as an independent coating, by analogy with hot-dip galvanizing, but, if necessary, can be used as a primer for various coatings and fire-retardant materials. It is not destroyed by UV radiation. Zinc plating, in contrast to hot dip galvanizing, is used to protect large-sized, hollow, thin-walled, lap-welded products.

Application and purpose

Zinc plating is used to protect critical structures in all types of corrosive environments activity, including aggressive and highly aggressive (C5 according to ISO 12944-5:2018), providing a guaranteed** protection period of 15 years or more with a layer thickness of 120 microns.

Zinc plating is used to protect construction and technological metal structures in industrial and civil construction, agriculture, fuel and energy facilities, road construction and transport construction, hydraulic structures.

Zinc plating is recommended for repair and restoration of previously galvanized (including other methods) metal structures without dismantling.

Zinc-rich coating

Coating is a thin-film zinc coating that protects effectively ferrous metals against corrosion. It has superior protection properties and high adhesion to metal surfaces

Zinc-rich coating

Сoating ensures simultaneous active (cathode) and passive (barrier) corrosion protection

Zinc-rich coating

Сoating is elastic, resistant to vibration and shock loads and abrasion, and functions within the temperatures -60°С to +150°С (for a short time, up to +180°С to +210°С during application of powder coatings)

Zinc-rich coating

Сoating is intended for anticorrosion protection of surfaces of industrial equipment and metal constructions installed outdoors and indoors

Workflow

The workflow for obtaining an anticorrosion coating based on Zinc-rich coating composition comprises the following sequence of six operations

The anticorrosion coating workflow is recommended to be maintained at an ambient temperature not lower
than -35°С.

To perform anticorrosion protection operations in winter, the following conditions should be met:

provide awnings or screening for protection against the elements;
the metal surface temperature should be no less than 3°С higher than the dew point temperature.

Sertificates

Conclusion ISO 12944 C5high

The samples used, designated as " Zinc composition (composition of the Zinker class, TU 2312-001-61702992-2009)", meet the requirements of the UNE-EN ISO 12944-6:2018 standard for the corrosion category "Very high level of C4" and "High level of C5". A very high level corresponds to a service life of at least 25 years, and a high level corresponds to 15 to 25 years according to UNE-EN ISO 12944-1:2018

Conclusion TSNIIKS

Zinc-filled coatings based on a Zincizing composition (TU 2312-001-61702992-2009) on carbon steel in aqueous environments (sea and fresh water) and atmospheric conditions are not inferior or superior in protective ability to hot zinc according to the results of tests by accelerated corrosion-electrochemical methods.

Conclusion of the TsNIIPSK named after Melnikov

The coating system has withstood 225 test cycles according to method 6 of GOST 9.401-91 (operating conditions of UHL1 according to GOST 9.104-79, atmosphere type II according to GOST 15150-69) with the preservation of protective properties up to A30 according to GOST 9.407-2015. Based on the results of accelerated climatic tests, taking into account the acceleration coefficient equal to 41 for the operating conditions of UHL1 (Appendix 10 of GOST 9.401-91), the predicted service life of the system in an open industrial atmosphere of moderate and the cold climate is at least 25 years old.

Conclusion of the Russian Maritime Register of Shipping

On the basis of the inspection and testing, it is certified that the products of "Zincing composition" meet the requirements of TU 2312-001 - 61702992-2009.

Conclusion MISiS

Steel metal structures with a zinc-containing coating with a thickness of at least 70 microns are resistant to atmospheric corrosion and are recommended for use in conditions of placement "under a canopy" when exposed to environments of weak and medium aggressiveness for a period of at least 50 years.

Ржавые трубы: как эффективно защитить трубопроводы от коррозии

Коррозия металла - явление, как уже успели понять постоянные читатели нашего блога, чрезвычайно распространенное и непредсказуемое. При наличии благоприятных условий она возникает буквально везде и повсюду. И если коррозию, которую элементарно видно невооруженным глазом, еще можно ликвидировать и не допустить ее повторного развития, то вот скрытая коррозия куда опаснее. В этой статье мы поговорим об особо уязвимых для ржавчины конструкциях - трубопроводах. Рассмотрим пути ее возникновения, разновидности, а также способы защиты.

Цинкирование и холодное цинкование: что выбрать? Сравниваем антикоррозионные технологии

Несмотря на то, что технология Цинкирования, известна довольно давно, многим знакома, хорошо изучена и основательно проверена, с ней все равно время от времени возникают сложности. Нет-нет, не применения – здесь как раз все отлично – а восприятия. Мы уже не раз рассказывали о том, как компании-подрядчики (в том числе и весьма крупные) медлят с внедрением новой технологии, потому что слишком зациклены на старых и не готовы отказаться от них.

ТОП-5 объектов, которые обязательно стоит защищать от коррозии

Ответ на вопрос: «Какие объекты нужно в первую очередь защищать от коррозии?» - звучит на самом деле очень просто: «Любые». Слишком уж вездесущая «рыжая чума», и слишком уж серьезными последствиями может обернуться ее неконтролируемое распространение. Тем не менее мы сделали для вас подборку из пяти объектов, где отсутствие надежной защиты от коррозии не просто недопустимо, а, можно сказать, смерти подобно

Коррозия и сельское хозяйство: как спасают от ржавчины фермы

Защита сельскохозяйственных объектов от коррозии - дело невероятно важное. И такое же сложное, ведь, помимо «стандартных» агрессивных воздействий, металлические конструкции, использующиеся в сельском хозяйстве, испытывают еще и целый ряд воздействий специфических, которым зачастую не способно противостоять абсолютное большинство «классических» антикоррозионных средств. Про нюансы и подводные камни, с которыми постоянно сталкиваются заказчики, изготовители и сборщики, а также про надежные способы их обхода расскажем вам в этой статье.

Почему покупатели выбирают составы класса Zinker?

Перед каждым, кто работает с металлическими объектами, рано или поздно встает вопрос: чем защищать металл от ржавчины? На рынке антикоррозионных средств несложно потеряться, настолько он обширен и богат товарами самых разных свойств и ценовой категории. В этом коротком ликбезе-путеводителе мы расскажем (и докажем!) вам, что ломать голову не стоит, когда есть одно максимально надежное, эффективное и современное решение. И это - технология под названием «Цинкирование»
