With increasing global awareness of environmental sustainability and workplace safety, industries are shifting toward water-based anti-corrosion coatings to protect steel and metal surfaces. These coatings offer strong corrosion resistance while drastically reducing volatile organic compounds (VOCs), making them ideal for use in construction, manufacturing, transportation, and energy infrastructure.
From primers to topcoats, the latest water-based coating systems are engineered to meet the dual demands of environmental compliance and industrial performance. In particular, products such as Water-based Alkyd Antirust Primer, Water-based Epoxy Zinc-rich Primer, and Water-based Acrylic Anti-corrosion Topcoat are now widely adopted for structural steel, bridges, storage tanks, and marine equipment.
Why Choose Water-Based Anti-Corrosion Coatings?
Unlike traditional solvent-based coatings, water-based systems use water as the primary solvent, significantly reducing harmful emissions and odor. This not only improves worker safety but also helps facilities comply with strict environmental regulations such as China's GB standards, EU REACH, and U.S. EPA limits.
Key benefits include:
Low VOC emissions and reduced environmental impact.
Non-flammable, non-toxic formulations for safer handling.
Excellent adhesion and corrosion resistance.
Wide compatibility with steel, iron, and galvanized metals.
Cost-effective for long-term maintenance and protection.
Now let’s take a closer look at some of the most widely used water-based anti-corrosion coatings on the market.
1 . Water-based Alkyd Antirust Primer
This primer is ideal for general-purpose corrosion protection on metal surfaces. Water-based Alkyd Antirust Primer offers good adhesion, flexibility, and resistance to rust in mild to moderate industrial environments. It is often used in light machinery, indoor steel structures, and pipelines where VOC restrictions are in place.
2 . Water-based Modified Alkyd Antirust Primer
Improved with special resin modification, Water-based Modified Alkyd Antirust Primer delivers enhanced drying speed, corrosion resistance, and film strength. It’s suitable for medium-duty protective systems and can be used as a base coat before applying water-based acrylic or polyurethane topcoats.
3 . Water-based Acrylic Antirust Primer
For faster drying and improved exterior durability, Water-based Acrylic Antirust Primer is a preferred choice. It provides excellent anti-corrosion performance along with UV and weather resistance, making it suitable for outdoor steel structures such as fences, lighting poles, and utility equipment.
4 . Water-based Acrylic Anti-corrosion Topcoat
Used as the finishing layer in water-based systems, the Water-based Acrylic Anti-corrosion Topcoat offers excellent gloss retention, weatherability, and color stability. When paired with compatible primers, it forms a durable barrier against moisture, oxygen, and industrial pollutants. This topcoat is widely used in infrastructure, metal panels, and transportation equipment.
5. Water-based Inorganic Zinc-rich Primer
Designed for use in highly corrosive environments, the Water-based Inorganic Zinc-rich Primer contains high-purity zinc powder that provides cathodic protection to steel substrates. It is ideal for heavy-duty protection in marine, offshore, and petrochemical applications, especially on large steel structures exposed to salt spray and chemicals.
6. Water-based Epoxy Zinc-rich Primer
This primer offers the perfect balance between corrosion protection and application versatility. The Water-based Epoxy Zinc-rich Primer is widely used in bridges, ports, pipelines, and heavy machinery. It provides excellent adhesion and long-term durability and can be followed by epoxy intermediate and polyurethane topcoat layers for complete protection.
7. Water-based Epoxy MIO Intermediate Paint
As a mid-layer in a multi-coat system, Water-based Epoxy MIO Intermediate Paint (Micaceous Iron Oxide) enhances the mechanical strength and barrier properties of the overall coating system. It resists water penetration, UV degradation, and surface cracking, making it essential in long-life protection systems for bridges, towers, and industrial equipment.
8. Water-based Two-component Polyurethane Topcoat
For the highest level of exterior durability, gloss retention, and abrasion resistance, the Water-based Two-component Polyurethane Topcoat is the final layer of choice. This coating resists chemicals, solvents, and weathering, and is widely applied in transportation, steel frameworks, machinery, and industrial buildings. It also meets the strictest low-VOC environmental standards.
