WL-J412 is a high-performance styrene-acrylic copolymer emulsion specifically engineered for waterborne industrial anti-corrosion coatings. Featuring a small particle size and optimized moderate viscosity, it exhibits excellent compatibility with various anti-rust agents and anti-rust pigments. Formulations based on this emulsions deliver outstanding water resistance, salt-water resistance, and long-lasting salt spray resistance. Furthermore, it is completely free of heavy metals and halogens, making it a highly reliable, eco-friendly solution for Primer and Topcoat In One Metal Anti-Rust Coatings.

As a key product in WangQin Chemical’s anti-rust system for water-based industrial coatings, WL-412 offers excellent anti-corrosion performance, good application properties, and eco-friendly characteristics, making it highly promising for applications such as steel structure corrosion protection and the refurbishment of color-coated steel roofing. It serves as an ideal film-forming agent for water-based industrial coatings, enabling manufacturers to produce high-performance metal protective coatings that meet environmental standards.

• Superior Anti-Corrosion Barrier: Formulated films deliver exceptional resistance against water, salt-water, and salt spray, providing long-lasting barrier protection for metal substrates.
• High Pigment & Filler Loading: Exhibits extraordinary binding capacity for pigments and fillers. It ensures strong substrate adhesion even at lower emulsion dosages, significantly optimizing formulation costs.
• Excellent DTM (Direct-to-Metal) Performance: Perfectly balances the anti-rust requirements of a primer with the hardness and gloss retention of a topcoat, allowing for efficient single-coat applications.
• Outstanding Compatibility & Recoatability: Highly compatible with mainstream anti-rust agents and reactive pigments. It features excellent interlayer adhesion, ensuring seamless recoatability .
• Eco-Friendly Compliance: 100% waterborne system free of heavy metals and halogens, fully complying with strict international environmental and low-VOC regulations..
