Innovative Technology Protects Against Corrosion, Boosting Energy Efficiency in Brazil

As Brazil stands out on the global stage as a leader in solar energy, the search for effective methods to prolong the lifespan of plant equipment has become a priority. Cold galvanizing emerges as a cutting-edge solution, offering a shield against corrosion, essential for maintaining the high productivity of solar installations. According to the Ministry of Mines and Energy, the country already has over 18,000 solar plants, which together produce 10.3 gigawatts annually, showcasing the immense potential of this renewable source.

The Battle Against Corrosion

Marcos Pacheco, a chemist at Quimatic, a manufacturer of specialty chemicals, emphasizes that cold galvanizing not only protects the metallic structures of photovoltaic plants against corrosion but also integrates into the metal, creating an impenetrable barrier against rust. This technology stands out compared to conventional methods, such as painting or using red lead, as it offers more durable and reliable protection.

Efficiency and Practicality

The equipment in solar plants, often exposed to adverse conditions, receives hot galvanizing from the factory. However, maintenance and interventions, such as cutting and welding, can compromise this initial protection. Cold galvanizing, easily applicable with a brush or spray gun, proves to be a practical solution for reinforcements or repairs, eliminating the need for disassembly or transportation of parts.

Pioneering and Innovation at Quimatic

Quimatic, a pioneer in introducing cold galvanizing in Brazil in the 1990s, offers two main solutions: CRZ, in dark gray, and GALVALUM, with an aluminized finish. Both options form a zinc layer that not only prevents direct contact of the metal with corrosive agents but also provides cathodic protection, where the zinc sacrifices itself before the base metal. This strategy ensures the integrity of the metal, even in the event of damage to the zinc layer.

Proven and Accessible Protection

With zinc of 99.9% purity, Quimatic’s solutions meet the stringent ASTM A 780 and ABNT 6323 standards. In corrosion resistance tests, these products demonstrated effectiveness exceeding 1,200 hours in salt spray chambers, equivalent to over five years of protection in extreme conditions. “Cold galvanizing allows solar energy plants in Brazil to significantly extend the lifespan of their equipment, keeping pace with the rapid growth of the sector,” says Pacheco.

Quimatic also offers a comprehensive online course on cold galvanizing, providing the knowledge and skills necessary to apply this technology effectively. This innovation represents a milestone in the maintenance and sustainability of solar plants, ensuring that Brazil continues to be at the forefront of clean and renewable energy production.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Workers were opening a modern road in Dover when they found, 6 meters below the asphalt, a 3,500-year-old boat made of stitched oak and plant fibers.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Motorcyclist sees excavator arriving at the edge of a river in Bosnia, calls neighbors in minutes and turns a hydroelectric project into a resistance lasting more than 10 years with five expired concessions.

Labubu dolls appear at the opening of the 2026 World Cup, steal the show in Mexico, and make many people wonder what serrated-tooth plush toys have to do with FIFA.

Family builds a house inside a giant greenhouse in Norway, grows fruits in winter, and creates an almost self-sufficient home with solar energy, biomass, and micro-hydroelectric power.

Why did so many players take the field with pink boots at the opening of the 2026 World Cup and how much does it cost to follow this trend?

Brazil put electric vehicles on the streets, but now it’s testing a solution for the side effect: used batteries from BYD buses can gain an additional 5 to 10 years of second life by storing solar energy at Unicamp after 500 cells are analyzed by CPQD.
