In recent years, rising global environmental awareness and increasingly stringent environmental regulations have created unprecedented opportunities for the development of water-based coatings in the casting industry. In China, the market for water-based casting coatings has grown by 7% year-on-year, driven by consistent demand from downstream sectors such as construction, automotive, and industrial manufacturing, as well as by the inherent safety and eco-friendly advantages of water-based formulations.

Water-based casting coatings use water as the primary solvent or dispersion medium and are typically categorized into three types:

• Water-soluble coatings

• Water-dilutable coatings

• Water-dispersible coatings (e.g., latex coatings)

Compared to traditional solvent-based coatings, water-based products significantly reduce the use of volatile organic compounds (VOCs), offering benefits such as lower toxicity, reduced flammability, and better environmental compatibility. Most of the volatile content in water-based coatings is water, which minimizes environmental pollution and enhances workplace safety. Additionally, water-based coatings feature strong adhesion, ease of application, and easy cleanup using water, reducing reliance on chemical solvents.

The competitive landscape in the water-based casting coating market is becoming increasingly diversified, with numerous domestic and international companies entering the field. As global demand for sustainable manufacturing continues to rise, water-based coatings are poised to capture a greater share of the market across industries. Moving forward, the focus will be on improving the environmental performance, safety, and functionality of these coatings, with innovation driving the launch of next-generation products.

At Xinda Casting, our water-based coating materials are engineered for low gas emission, reducing the risk of porosity defects in castings. They also offer excellent anti-stick properties, no cracking or bubbling after drying, and high strength at both ambient and elevated temperatures. As technology advances, we remain committed to continuous product innovation, improving performance, expanding applications, and increasing market competitiveness through the development of new formulations, materials, and production processes.
