Industrial process tanks, chemical tanks and storage tanks are exposed daily to conditions that conventional construction materials cannot withstand. Strong acids, alkalis and high temperatures will immediately damage carbon steel and concrete without technical protection. Corrosion weakens structures, jeopardises the continuity of the process and is detrimental to safety at work and the environment. The protection provided by traditional epoxy paints or elastic coatings is often short-lived, increasing maintenance intervals and downtime. ARC composite technology has been developed specifically for these demanding applications. It allows tanks to be coated on site, raising the chemical resistance and mechanical strength of the structure to a professional level. <\/p>\n

Chemical stress and corrosion: the need for protection of steel structures<\/h2>\n

The life cycle of industrial tanks is primarily limited by chemical corrosion. Although carbon steel is a structurally strong material, it is sensitive to oxidation and chemical attack. For example, sulphuric acid, lye and abrasive sludges thin the steel surface or cause pitting corrosion. Pitting corrosion can penetrate the tank wall over a very small area, even if the rest of the structure appears intact. A small hole is enough to cause a shutdown of the entire plant, underlining the importance of preventive coating. <\/p>\n

Effects of corrosion on industrial structures<\/h4>\n

Financial losses<\/span> Unplanned maintenance outages<\/strong><\/div>\n<\/div>\n

In concrete tanks, chemicals penetrate the porous material, which corrodes the reinforcement and cracks the concrete. Effective coating of the tanks<\/a> creates an impermeable barrier between the chemical and the base material. ARC composites stop the deterioration process by chemically and mechanically bonding to the surface. This prevents chemicals from coming into contact with the substrate, extending the life of the tank by decades and saving on costly reinvestment. <\/p>\n

ARC composites and traditional coatings: a technical comparison<\/h2>\n

Standard epoxy paints and polyurethane coatings are not always sufficient for demanding chemical resistance. Polyurea works well for waterproofing, but its resistance to strong acids or solvents is limited. Professional ARC composite coatings<\/a> are made from ceramic reinforced composites with a dry solids content of 100%. <\/p>\n

\n
\n
High ceramic content<\/h5>\n

Ceramic reinforcements make the surface extremely hard. The surface resists abrasion and mechanical wear much better than conventional plastic-based coatings. <\/p>\n<\/div>\n

\n
Chemical bonding<\/h5>\n

The composite forms a dense polymer network that repels aggressive liquids. It prevents the absorption of chemicals and protects the substrate from corrosion. <\/p>\n<\/div>\n<\/div>\n

The technical difference is highlighted by the maintenance intervals. Properly selected and installed, ceramic composite will last for years longer than traditional painting. ARC coatings retain their properties even at hundreds of degrees Celsius, which is essential in the temperature fluctuations of the process industry. The thermal expansion coefficient of ARC composite is optimised to match that of steel, preventing delamination even under harsh conditions. <\/p>\n

On-site coating of large solid structures is often the only economically viable solution. The composite can be applied by spraying or by hand, depending on the geometry of the object and the required thickness. The end result is a seamless and chemically inert surface that makes the tank virtually maintenance-free for long periods of time. <\/p>\n

Primer and installation: steps to a successful coating project<\/h2>\n

On-site tank coating requires technical precision. Substrate preparation is crucial, as the adhesion of the ceramic composite requires a clean and sufficiently rough surface. Steel substrates are usually spray cleaned to Sa 2\u00bd to remove all rust and contaminants. Careful pre-treatment ensures that the coating forms a cohesive and durable bond with the base material. <\/p>\n

\n

Technical requirements for pre-treatment<\/h4>\n
Degree of purity (Steel)ISO 8501-1 Sa 2\u00bd<\/strong><\/div>\n
Surface profile75-125\u00b5m (sharp anchoring pattern)<\/strong><\/div>\n
Concrete moisture contentAll4 % (by weight)<\/strong><\/div>\n<\/div>\n

A durable ARC composite coating<\/a> is applied to the prepared surface, either by high pressure spray or by hand. Spraying is effective on large surfaces, while hand-applied compounds are suitable for flanges, mixers and corners. During the work, the dew point and temperature are controlled to ensure that the chemical curing process proceeds correctly and the surface is fully dense. <\/p>\n

Protection under extreme process conditions<\/h2>\n

Ceramic reinforced coatings are designed for applications where conventional solutions will not last. Sulphuric acid tanks, lye ponds and sludge treatment systems require protection that prevents the penetration of small chemical molecules. ARC coatings’ leak-proof design keeps the tank structure safe from corrosion and significantly extends the life of the equipment. <\/p>\n

\n
\n
Oxygen resistance<\/h5>\n

Resistant to strong acids (e.g. H2SO4, HCl) without softening the surface.<\/p>\n<\/div>\n

\n
Duration of erosion<\/h5>\n

Ceramic particles protect the surface from abrasive sludge and flow.<\/p>\n<\/div>\n

\n
Temperature tolerance<\/h5>\n

Maintains its strength at high temperatures and during steam cleaning.<\/p>\n<\/div>\n<\/div>\n

In the food and bio-industry, sugars, organic acids and cleaning chemicals are constantly stressing surfaces. ARC composite provides a glassy smooth surface that is easy to clean and prevents bacterial growth. The smooth surface also reduces flow resistance in piping systems, which can result in long-term energy savings. <\/p>\n

Life cycle costs and return on investment<\/h2>\n

Although the initial cost of ceramic composite is higher than traditional painting, the life cycle costs are significantly lower. Professional tank coating<\/a> multiplies service intervals. According to industry experts, service intervals can be up to 3-5 times longer than with traditional methods. This reduces unplanned downtime, which is costly for an industrial plant. <\/p>\n

Refurbishing a tank with a coating costs a fraction of the cost of buying and installing a new tank. On-site work eliminates the need to move or demolish structures. With ARC coating, an old tank will perform as well or better than a new one, making it an economically and environmentally sustainable choice. <\/p>\n

The longevity of industrial tanks is ensured by expert implementation and the right choice of materials. ARC composite technology combines chemical protection, mechanical strength and installation flexibility. It secures the operation of an industrial plant without fear of unexpected corrosion damage or leaks, even under challenging conditions. Technical protection is a sure way to ensure trouble-free production for decades to come. <\/p>\n
