Solvent-Free Anti-Corrosion Coating
Product Overview
Solvent-free anti-corrosion coating is a high-performance, two-component epoxy coating composed of high-performance, low-viscosity epoxy resin, ultra-fine corrosion-resistant pigments and fillers, specialized additives, and an imported polyamine adduct curing agent. This product is specifically designed to meet the heavy-duty anti-corrosion requirements of steel and concrete structures. It can be used either as the topcoat in a heavy-duty anti-corrosion system or applied independently as a combined primer-and-topcoat, offering excellent anti-corrosion, waterproofing, and chemical resistance properties while complying with stringent environmental regulations for low VOC emissions. It is suitable for anti-corrosion applications under a wide range of complex operating conditions.
Technical Principle
Solvent-free anti-corrosion coating achieves its protective performance through the cross-linking and curing mechanism of a two-component epoxy system: the epoxy resin serves as the film-forming base material, providing outstanding adhesion and resistance to chemical media; when combined with ultra-fine corrosion-resistant pigments and fillers, it forms a dense physical barrier on the substrate surface, effectively preventing the penetration of water, oxygen, and various corrosive agents. Meanwhile, the imported polyamine adduct curing agent reacts with the epoxy resin to form a three-dimensional network structure in the coating film, endowing it with exceptional mechanical strength and adhesion. Since the formulation contains no volatile organic solvents, the curing process produces no solvent evaporation, thereby eliminating the porosity issues commonly associated with traditional solvent-based coatings and further enhancing the coating’s density and long-term corrosion resistance.

Target Customer Groups
Heavy-duty anti-corrosion contractors, municipal infrastructure developers, operators of petrochemical storage tanks, wastewater treatment project builders, shipbuilding and repair companies, industrial plant anti-corrosion service providers, and concrete structure protection teams
Application Scenarios
This product is suitable for a wide range of scenarios requiring robust anti-corrosion protection, primarily serving as the topcoat for heavy-duty anti-corrosion systems on steel structures such as petrochemical storage tanks, oil pipelines, steel-framed factories, bridge steel structures, and ship cabins. It can also function as a combined primer-and-topcoat for concrete structures, including sewage treatment ponds, underground garage floors, municipal water facilities, and concrete bridge piers. It is particularly well-suited for applications in enclosed spaces or environments with poor ventilation, such as the interiors of underground storage tanks, small cabins, and underground sewage pools.
Addressing Industry Pain Points
1. Solving the Problem of High VOC Levels in Traditional Solvent-Based Coatings: Completely free of volatile organic solvents, with VOC content ≤50 g/L, meeting environmental regulatory requirements, avoiding penalties for non-compliance during environmental inspections, and eliminating unpleasant odors during application to improve working conditions.
2. Tackling Excessive Porosity and Shortened Corrosion Resistance: The solvent-free formulation results in a dense, seamless coating film that effectively blocks the penetration of water, oxygen, and corrosive agents, significantly extending the service life of the coating and reducing future maintenance costs.
3. Overcoming Issues of Thick-Coat Sagging and Low Application Efficiency: Supporting single-coat application, this product avoids the sagging common in thick coatings, shortens construction timelines, boosts efficiency, and saves labor costs.
4. Mitigating Safety Risks in Confined Spaces: With no solvent evaporation, it eliminates the risk of fire or explosion associated with solvent release in poorly ventilated areas like underground storage tanks or small cabins, reducing safety precautionary measures and enhancing overall construction safety.
