Fire protection of metal structures of industrial objects
Indoor fire protection
Fire- proof coatings with primer GF-021
Fire-proof paints PLAMCOR are compatible with the primer GF-021 widely used in construction. This primer is considered to be the cheapest and most widespread materials. However, it has certain disadvantages. Service life period is one year when metal structures are located in the open air , however, the technological gap between application of the priming coat and application of the fire-proof coat may turn out to be several years. In this connection in many cases when the fire-proof paint is applied on metal structures the corrosive damage is already present. This fact results in violation of the technological conditions and impairs effectiveness of the fire-proof coating.Fire- proof coatings with the highest protective properties
To create the coatings ensuring long-term protection from corrosion and fire , the VMP Holding Company puts forward advanced and innovative primers with enhanced protective properties: ISOLEP-primer (epoxy with zinc phosphate) and VINICOR -061 (vinyl-epoxy). These materials provide for reliable protection of metal structures from corrosion during the standby period before application of the fire-proof coat.Fire- proof coatings with the highest protective properties
To protect steel structures in aggressive environment ,namely when dealing with chemical, metallurgical, oil-gas production facilities , the VMP Holding Company recommends to use coating systems based on zinc-rich primers ZINEP, ZINOTAN, ZFES, ZINOL. They demonstrate highest anticorrosive properties, since they protect steel through “cold” zinc galvanizing. It is worthwhile to employ the fire-proof coating composition PLAMCOR which is chemically stable.primer | fire-proof paint | top enamel* | |||

* to ensure aesthetically pleasing appearance or protection from aggressive environment the following top enamels are recommended for use: acrylic POLYTON –AK , polyurethane POLYTON-UR, acryl-urethane POLYTON-UR(UV) or vinyl-epoxy VINICOR-62;
** thickness of coating depends on the fire-resistance time/ rating and metal thickness.
Fire protection of open-air located objects
To protect the open-air located objects the VMP Holding Company has developed the weather-resistant composition PLAMCOR -3 which may be used without top paint materials. Enamels for finishing purposes are used when dealing with color solutions.
It is recommended to use composition PLAMCOR -3 with the primers which show improved and very good protection properties , since there is no point in using fire-proof paint with extended life and the primer with short life.
