Protection of physical assets, facilities and production lines in parent and process industries is the cornerstone of productivity and significant reduction of capital costs. Metal equipment, chemical transmission lines, steel structures, pipelines and advanced machinery all operate in highly corrosive, wet, acidic environments and under continuous mechanical wear. In such a challenging situation, accurate knowledge of industrial colors and their application in manufacturing industries is not just an appearance or taste choice, but an engineering necessity for the stable continuation of factories. Advanced coating systems prevent microscopic and macroscopic degradation of substrates and multiply the useful life of assets. As an innovative and specialized authority in industrial coating engineering, Negin Fam Iranian Company has designed and formulated modern painting systems in accordance with the strict requirements of global standards so that the country's industries achieve the highest level of structural stability and economic efficiency.
Industrial coatings are complex chemical formulations that consist of a precise combination of polymer resins, anticorrosive and colorant pigments, compatible solvents, and additives that improve rheology and optical stability. In today's modern industries, thin layers of paint are responsible for consolidating an impermeable barrier against moisture, oxygen, active chloride ions, and thermal shocks. To achieve the ideal performance of these coatings, it is necessary to master the chemical behavior of paint layers and match it with the operating environment. Over many years, Negin Fam Iranian Company has been able to take a fundamental step in reducing economic losses caused by depreciation in heavy industries, oil and gas, petrochemical, automotive and infrastructure facilities by providing detailed technical advice, analyzing the atmospheric conditions of factories and producing new generation paints.
The nature of industrial paints and its distinction with building coatings
Building paints are mainly formulated for aesthetic purposes and in environments with physiological stress and mild weather. On the contrary, the types of industrial paints and their application in manufacturing industries are based on tensile strength, interlayer adhesion, chemical resistance, protection against ultraviolet rays, electrical stability and cathodic corrosion inhibition. In the specialized production coatings of Nagin Fam Iranian Company, indicators such as mechanical strength, flexibility of the paint film and water repellency are evaluated in laboratory tests simulating supercritical conditions to ensure that the formed polymer layer does not suffer from cracking, blistering or peeling.
Comprehensive classification of all types of industrial paints and chemical structure of resins
Knowing the structure of resins is the most basic step in the correct selection of the paint system, because the behavior and final properties of the coating are completely dependent on the monomer bonds and chemical reactions forming the paint film. Negin Fam Iranian Company has compiled and produced a wide range of these specialized coatings suitable for alkaline, acidic, hydrocarbon and atmospheric environments. In the following, we will analyze in depth the types of industrial paints and their use in manufacturing industries so that process engineers can make a safe and lasting choice.
Epoxy paints and corrosion resistant coatings
Epoxy coatings are the most well-known protective barrier in manufacturing industries due to the presence of stable oxiron rings and strong transverse bonds. These types of coatings show excellent adhesion to metal and concrete surfaces and provide exceptional resistance to water penetration, petroleum substances, fuels and corrosive chemicals. The epoxy paint systems of Neginfam Iranian company are available in different types such as zinc-rich primers, intermediate epoxies with mica oxide pigments to reduce the path of moisture penetration, and polyamide and polyamine topcoats. The use of the complete epoxy system of Nagin Fam Iranian Company guarantees the resistance of the layers against destruction and peeling even in the conditions of complete immersion in industrial liquids.
Among other attractive formulations of this category are epoxy mastics with a high volume solid percentage, which provide the ability to be applied on surfaces with medium surface preparation. When complete sandblasting is not possible, these products provide factory maintenance managers with an extremely effective solution and prevent hidden rust layers from advancing.
Polyurethane paints and light protection properties
Two-component polyurethane colors are formed from the bonding reaction of polyol compounds and aliphatic or aromatic isocyanates. The obvious strength of the aliphatic polyurethanes formulated in Naginfam Iranian company is their amazing resistance to the harmful ultraviolet radiation of the sun. Polyurethane basecoats offer excellent gloss, long-lasting color retention, and mechanical properties including excellent wear and impact resistance. For this reason, in multi-layer industrial painting systems, polyurethane coating is always used as the final top layer on epoxy systems to prevent the phenomenon of plastering of epoxy layers due to sunlight.
The proper elasticity of these colors makes the repeated thermal expansion and contraction of metals to be avoided without creating microcracks on the surface of the coating. Polyurethane surface systems of Negin Fam Iranian Company in open atmospheric environments, open port facilities and the surrounding walls of cooling towers of petrochemical factories, display a premium appearance and perfect technical stability.
Industrial alkyd paints for mild stress atmospheres
Alkyd paints are made on the basis of polyester resins modified with vegetable fatty acids and are dried by the mechanism of oxidation and solvent evaporation. Although the chemical resistance of these coatings is not equal to two-component epoxy polymer systems, due to easy application with brush, roller and spray, reasonable economic cost and high adaptability to different surfaces, they have a very important place in protecting semi-heavy equipment, packaging lines, structural skeletons of production sheds and auxiliary machinery of workshops. Negin Fam Iranian Company produces modified alkyd primers with anti-corrosion compounds such as zinc phosphate for higher efficiency of these resins.
Silicone heat resistant paints for extreme heat stress
In equipment such as recovery furnaces, industrial exhausts, flares, boilers and hot chimneys in manufacturing plants, conventional polymer coatings disintegrate in a fraction of an hour due to thermal degradation. This is where silicone-based heat-resistant paints come into play. Methyl-phenyl silicone resins formulated in Nagin Fam Iranian Company are combined with special aluminum fillers and ceramic fibers and show the ability to withstand shocks and temperatures beyond 200 to 600 degrees Celsius without burning, severe color change or separation. These layers prevent the acute oxidation of steel due to the sudden temperature of the furnace and prevent fatal structural damage.
Vinyl and chloro rubber paints with high flexibility and impermeability
This category of coatings are synthesized based on thermoplastic polymers, which have a flexible structure and very low impermeability against the passage of water vapor and sour gases. Due to the lack of dependence on external curing agents, they dry quickly and provide brilliant performance in coastal structures, sewage tanks, hydraulic structures of dams and concrete foundations exposed to salt water. The products of Negin Fam Iranian Company in this category prevent the migration of solutes into the fabric of production structures by creating a continuous molecular connection.
Environmentally friendly electrostatic powder paints
Application of various types of industrial paints in different sectors of manufacturing industries
Automotive and component manufacturing industries
In car manufacturing lines, car bodies and truck chassis are coated with multi-layer systems of cathodic immersion and electrodeposition paints, and then filler intermediate liners and gloss anti-scratch polyurethane paints sit on them. The task of this coating chain is to neutralize the effects of road anti-freeze salts, atmospheric acid secretions, sandblasting and abrasion caused by the wind. Providing the needs of car parts painting by the products of Negin Fam Iranian Company brings an improvement in appearance class and resistance to salt spray tests in the salt spray chamber.
Oil, gas, petrochemical and refineries industries
Petrochemical environments are full of sulfur compounds, aromatic cyclic compounds, volatile acids and cooling saline waters. Storage tanks, aboveground and underground pipelines, offshore steel structures and loading docks require epoxy glass flake systems with micron glass particles and hard polyurethane topcoats. As a pioneer in the engineering of oil and gas coatings, Neginfam Iranian Company has formulated a variety of zinc-rich linings along with specialized piping primers and coatings resistant to produced water and sour gas to protect the country's strategic facilities from crippling corrosion.
Food, pharmaceutical and health industries
Food processing factories and pharmaceutical lines are environments with very strict hygiene standards. Walls, ceilings, floors and industrial machinery equipment in these places are washed daily with acidic, alkaline and hot water detergents. The types of industrial paints and their application in the manufacturing industries of this area are focused on solvent-free sanitary paints, special epoxies for seamless, antibacterial and non-toxic surfaces for accidental contact with food. The products of Negin Fam Iranian Company prevent the accumulation of molds, the penetration of fungal contamination and the release of unpleasant odors in sterile pharmaceutical production halls.
Marine industries and port facilities
The hulls of floats, ocean liners, buoys and giant cranes of the docks are in constant turmoil with the salty sea water and violent waves. In addition to rapid electrochemical corrosion, the deposition of algae and sticky marine organisms reduces the movement efficiency of vessels and increases fuel consumption by 40%. The anti-moss paints and marine epoxy systems of Negin Fam Iranian Company prevent the biological attachment of these organisms to the steel plates and neutralize the mechanical erosion of the outer shell of the metals in deep water.
Metal industries, sheds and construction of heavy equipment
Prefabricated skeletons, steel bridges, power transmission pylons and storage tanks of factories are exposed to continuous rainfall, summer stress and acid rain. The use of epoxy zinc phosphate primers with an industrial polyurethane top layer, which is engineered by Neginfam Iranian Company, guarantees resistance to atmospheric degradation in mountainous, hot and dry climates, and eliminates the need for costly overhaul and restoration operations for many years.
Economic and technical benefits of using high-quality industrial coatings
The initial investment for the implementation of engineering paint systems constitutes a very small percentage of the total value of assets of a manufacturing plant. However, economic analysis in industrial projects has proven that the use of low-quality or inappropriate paints will result in staggering costs of sudden stoppage of the production line and replacement of rotten iron. Investigating various types of industrial paints and their application in manufacturing industries will gain strategic value when the duration of periodical inspections of equipment will be significantly longer.
Equipments that are protected with high-quality covers of Negin Fam Iranian Company, in addition to being stable against destruction, increase the safety factor of the work environment and minimize the human errors of personnel by maintaining brightness and warning signs. Synchronization of rheological properties, uniform dry film thickness and excellent adhesion to metal in precious colors prevents premature blistering and gives manufacturing companies a more stable financial flow.
Surface preparation requirements to achieve maximum color efficiency
The best paints in the world, if applied on an unprepared, greasy, salted surface or full of loose oxide scales, will crumble and peel off in the shortest possible time. Standardization of the substrate before spraying each layer is a definite prerequisite in industrial coating systems. The cleaning process by spraying sand and steel granules, or sandblasting, according to standards such as semi-white surface, causes the complete removal of oxide layers and creates a certain roughness as a mechanical tooth. This roughness of the substrate multiplies the surface involved in the adhesion of Negin Fam Iranian resins.
Cleaning the surface from fats and oils caused by machining processes with solvent washing, measuring the dissolved salts remaining on the metal, checking the dew point of the environment to avoid the formation of invisible water droplets during the coating and checking the temperature of the part are considered integral steps in coating engineering. In all sensitive projects, the technical team of Nagin Fam Iranian Company provides detailed step-by-step instructions for surface preparation in order to record the highest pull-off and interlayer adhesion test indicators.
Modern methods of color application in production lines
The spraying method plays a direct role in creating a dry film layer without pores, blisters and dripping. In small industries and restoration projects, the use of hand tools such as rollers or brushes may be efficient, but in large factories, the industry standard of the day focuses on the use of airless or airless spray technology. In this method, the paint liquid is atomized with very high hydraulic pressures from the narrow nozzle opening and without carrying air particles, it leaves a uniform layer with high thicknesses on the structure at each stage.
In the facilities of continuous lines, the electrostatic application of liquid and powder paints brings the most savings in raw material consumption and the uniformity of the film in the corners and angles of the piece. The specialized paints of Negin Fam Iranian company, with the ideal balance of viscosity and thixotropic flow characteristics, make the spraying process with airless devices extremely smooth and reduce the possibility of undesirable phenomena such as smudging or eye-fishing of the paint to zero.
