Industrial process equipment such as mixers, pumps, tanks and pipelines are constantly subjected to forces that test the durability of materials. Mechanical wear, cavitation and chemicals such as acids and bases corrode unprotected surfaces. Damaged components lead to costly production downtime and force premature equipment investments. Traditional metal alloys or ordinary paint surfaces rarely provide adequate protection under these harsh conditions.
ARC coating offers a technical solution to these maintenance challenges. It is a high-performance composite material developed for the specific needs of demanding industries. ARC coatings are used to protect new equipment and repair damaged components. Often the end result is more durable than the original surface. ARC technology is based on proven protection performance that improves the efficiency of industrial processes and ensures long equipment life.
What is ARC composite coating based on?
ARC (Advanced Reinforced Composites) represents the cutting edge of surface treatment technology. It combines polymer science and technical reinforcements in a way that differs from conventional industrial paints. ARC composites form a thick and structural protective layer that is chemically bonded to its substrate. The coating consists of a liquid polymer matrix reinforced with ceramic particles, glass flakes or technical fibres.
Technical structure of ARC composite
Ceramic reinforcements are crucial for wear resistance. When sand, silt or other abrasive particles hit the surface, the hard ceramic structure absorbs the impact and protects the underlying steel or concrete. The surface material does not thin, which is vital for mixer platforms and pump nests. The material is designed to retain its dimensions as it hardens. This ensures a tight joint that will not crack or come loose even under extreme temperature fluctuations.
Wear resistance and chemical protection in demanding conditions
ARC coating works in areas where steel, conventional floor coatings or polyurea cannot. Maintenance data shows that a properly selected composite coating multiplies the life of industrial mixers and pumps compared to an unprotected surface. Durability is based on mechanical strength and a wide range of chemical resistance.
Erosion and corrosion prevention
Protects surfaces from the wear and tear of moving liquids and solids, preventing the walls from thinning.
Chemical resistance
Resistant to strong acids, alkalis and solvents that would quickly destroy the base material.
Temperature duration
Maintains protective properties and adhesion under high temperatures and sudden thermal shocks.
For example, in sulphuric acid tanks, the surface material is subjected to constant chemical stress. The dense molecular structure of ARC coatings prevents chemicals from penetrating the layer and reaching the substrate. The smooth surface improves flow dynamics and reduces material adhesion to mixers or pipeline walls. This protects the equipment and improves the energy efficiency of the process by reducing friction. In sites where steel pipes were previously replaced annually, the coating has achieved a maintenance-free period of several years.
Lifecycle cost management and component refurbishment
In industrial maintenance, investments are driven by the life cycle costs of the equipment. A worn mixer or corroded pump housing does not automatically require expensive new investment. Professional ARC coating allows equipment to be restored to original tolerances at a fraction of the cost of new equipment.
The composite material is able to rebuild the lost surface. If the steel surface has been thinned by mechanical wear, the ARC material restores the original shape and strength of the surface. The coating stops the damage from progressing and often improves the performance of the equipment. In pumps, the smooth composite surface reduces turbulence, which lowers energy consumption and prevents cavitation.

Cost benefits and technical efficiency
Applications: mixers, pumps and tanks
ARC technology is suitable for applications where traditional painting or rubber coating will not last. In the process industry in particular, the lifetime of materials determines the level of production reliability.
Mixers and agitators: blades and shafts are subject to constant abrasion. The ARC coating forms a slippery shield that repels abrasive particles. This prevents loss of mixing performance and keeps service intervals predictable.
Pumps and tanks: high quality tank coatings and pump maintenance are key applications. When the pump housing is protected with a composite, it is much more resistant to corrosion. This means fewer emergency repairs and more reliable production.
Industrial pools: when handling acids and strong alkalis, the coating must be impermeable. ARC composites can withstand sulphuric acid, for example, without embrittlement or delamination from the substrate.
Pumps and valves
Controlling cavitation and improving flow characteristics.
Mixing paddles
Maximum wear resistance in abrasive masses.
Heat exchangers
Protecting pipe plates and end caps from corrosion.
Technical know-how is as important as the material used in the coating process. Careful pre-treatment and sandblasting ensure adequate chemical adhesion. Without careful priming, the composite will not reach its full lifetime. Professional execution ensures that the protective layer can withstand shocks and large temperature fluctuations.
ARC coating is a justifiable choice for installations that aim for high utilisation rates. It provides technical protection where conventional materials reach their limits. By extending equipment life and reducing downtime, overall process efficiency is improved and maintenance costs are kept under control.
