Waterborne coatings are environmentally friendly industrial coatings that use water as the dispersing medium and contain little to no volatile organic solvents. It is the core product category that will lead the replacement of traditional solvent-based coatings in the coating industry by 2026. Anhui Jindun New Materials Technology Co., Ltd., a professional service provider with many years of expertise in industrial coatings, has compiled this industry‑specific solution for waterborne coatings based on its extensive experience serving thousands of industrial clients. This solution offers compliant, **, and cost‑effective green coating pathways tailored to manufacturing enterprises of varying sizes.

Core Application Context of the 2026 Waterborne Coatings Industry Plan

In 2026, the green transformation of China’s coatings industry has accelerated significantly. Waterborne coatings, renowned for their environmental benefits, have already achieved large-scale adoption across multiple sectors, including construction machinery, automotive components, rail transit, and home‑building materials. According to surveys conducted by leading industry research firms, the penetration rate of waterborne coatings in the industrial segment has surpassed 38%, an increase of 11 percentage points compared with 2025.

Trends in Coating Industry Transformation Under Domestic Environmental Policies

In 2026, local authorities across the country will progressively update their regulations on the control of volatile organic compound (VOC) emissions, further tightening emission standards for coating processes. Many regions have already mandated that all newly built coating production lines must use low-VOC, environmentally friendly coatings. As a result, the application scope of traditional, high-pollution oil-based paints is steadily shrinking, and waterborne coatings have become the primary choice for companies seeking to meet regulatory requirements.

Latest statistical data on the penetration rate of waterborne coatings in the industrial sector

According to an industry report released by the Coatings Industry Association in 2026, the penetration rate of waterborne coatings in the construction machinery sector has already reached 62%, while in the steel structure anti-corrosion segment it stands at 47%. In the residential wood‑finish paint market, the penetration rate has surpassed 55%. It is projected that by 2027, the overall industry-wide penetration rate will exceed 50%, marking the full transition into the era of waterborne coating applications.

Core Category Matching Rules for the Waterborne Coatings Industry Solution

Waterborne coatings are not a single product category; rather, they constitute a comprehensive system encompassing multiple sub‑categories, such as waterborne primers, midcoats, topcoats, and functional coatings. To meet both environmental regulations and performance requirements, it is essential to select coating products tailored to the specific characteristics of each application scenario.

Key Considerations for Selecting Waterborne Coatings Specifically Designed for Metal Corrosion Protection Applications

For metal corrosion‑protection applications such as steel structures, construction machinery, and storage tanks, key performance criteria to consider during product selection include the waterborne coating’s salt‑spray resistance, adhesion, and impact resistance. For typical outdoor environments, it is recommended to use a waterborne epoxy primer with a salt‑spray resistance of over 500 hours, paired with a waterborne polyurethane topcoat, to achieve long‑term corrosion protection lasting 3–5 years.

Adaptability Requirements for Waterborne Coatings Applied to Plastic and Building Material Surfaces

For low‑surface‑energy substrates such as PP plastic, ABS plastic, and furniture panels, it is essential to prioritize testing the adhesion performance of waterborne coatings on these materials during material selection. For certain specialized substrates, pre‑treatment with surface plasma or application of a dedicated waterborne adhesion promoter is required to prevent issues like coating delamination or wrinkling in later stages.

Application and Construction Steps for Waterborne Coatings in Different Market Segments

Standardized application is a critical step in ensuring the final performance of waterborne coatings. In mainstream industrial coating applications, a unified, standardized application process is employed, which can significantly reduce defect rates and extend the overall service life of the coating.

1. Substrate pretreatment: Remove rust, oil, and dust from the substrate surface by sandblasting, grinding, or other methods, achieving a surface roughness that meets the Sa2.5 standard.
2. Primer application: Adjust the viscosity of the water-based coating according to the product instructions, and apply one uniform coat of primer using high-pressure airless spraying. Allow it to stand at room temperature for 30 minutes until surface‑dry.
3. Intermediate coat and topcoat application: Apply the waterborne intermediate coat and then the waterborne topcoat in sequence, allowing sufficient drying time between each coat.
4. Performance Testing: After the coating has been applied and allowed to stand for 72 hours to achieve complete film formation, specialized tests are conducted to evaluate adhesion, coating thickness, impact resistance, and other relevant parameters.

A Comparative Analysis of the Total Costs of Water-Based Coatings vs. Traditional Oil-Based Coatings

Many companies worry during the selection phase that the total cost of waterborne coatings is too high. However, based on the latest industry market data from 2026, the long-term total cost of ownership for waterborne coatings is, in fact, more competitive than that of traditional solvent-based coatings. The specific comparative data are presented in the table below:

Industry consensus holds that, as environmental compliance costs continue to rise, the life-cycle cost advantage of waterborne coatings is expected to widen further over the next two to three years.

Common Challenges in Implementing Solutions for the Waterborne Coatings Industry and Approaches to Overcome Them

Many companies encounter various compatibility challenges during the initial phase of switching to waterborne coatings. Drawing on Jindun New Materials’ years of hands-on service experience, most common issues have well‑established optimization solutions, enabling rapid adjustments and seamless adaptation.

Optimization Strategy for Film Formation of Waterborne Coatings in Low-Temperature Winter Conditions

When the ambient temperature during application falls below 5°C, the film‑forming efficiency of waterborne coatings declines significantly. To raise the temperature to above 10°C, additional heating fans or drying equipment can be installed in the application area, and by incorporating a dedicated waterborne film‑forming aid, normal film formation can be ensured, preventing issues such as cracking and chalking.

Techniques for Enhancing the Performance of Waterborne Coatings in High-Salt-Spray Corrosion Environments

For high-salt‑fog, highly corrosive environments such as coastal areas and chemical industrial parks, an additional waterborne zinc‑rich primer can be applied to the standard waterborne coating system, increasing the overall zinc‑powder content. The resulting optimized coating can easily exceed 1,000 hours of salt‑spray resistance, fully meeting the stringent anti‑corrosion requirements of demanding applications.
