Basic Definition of Waterborne Coatings and the Industry Development Context in 2026

Water-based coatings are an environmentally friendly category of paints that use water as the diluent and contain no organic solvents. Currently, it has become the core direction for replacing traditional solvent-based coatings in the industrial coating sector. According to publicly available data from the China Coatings Industry Association in 2026, the penetration rate of waterborne coatings in China’s industrial sector has risen to 47%, doubling compared with five years earlier. Anhui Jindun New Materials Technology Co., Ltd., a manufacturer deeply rooted in the industrial coatings field, began investing in R&D related to waterborne coatings as early as 2019 and has now established a full‑range production line for industrial waterborne coatings.

1.1 Policy-Driven Context of the Waterborne Coatings Industry

In recent years, China has steadily tightened its regulatory standards for VOC emissions from industrial coatings, with numerous provinces and cities introducing policies to restrict the use of solvent-based paints. As a low-emission, environmentally friendly alternative, waterborne coatings have become the preferred choice for most manufacturers seeking to upgrade their coating processes. Industry experts widely anticipate that, by 2030, waterborne industrial coatings will account for more than 70% of the market, with their range of applications continuing to expand.

1.2 Current Status of Technological Evolution in Waterborne Coatings

By 2026, mainstream waterborne coating products have overcome the earlier technical limitations of poor corrosion resistance and slow drying times. The overall performance of certain high-end industrial‑grade waterborne coatings now rivals that of solvent‑based coatings in the same price range, while retaining their environmental advantages and meeting the needs of most standard industrial coating applications.

Introduction to the Main Industrial Product Categories of Waterborne Coatings

Currently available industrial‑grade waterborne coatings can be categorized into distinct product lines based on two primary dimensions: the film‑forming resin and the application scenario. These categories differ significantly in their suitable applications and performance characteristics, so companies should select products that align with their specific needs.

2.1 Common Categories Classified by Film-Forming Substances

Currently, mainstream industrial waterborne coatings fall into three major categories: waterborne acrylics, waterborne epoxies, and waterborne polyurethanes. The distinct film-forming matrices of these product lines directly determine their core performance characteristics: for example, waterborne acrylics excel in weather resistance, making them ideal for coating outdoor components; waterborne epoxies prioritize adhesion, rendering them well-suited for metal substrates; and waterborne polyurethanes emphasize wear resistance, making them appropriate for surfaces subject to frequent abrasion.

2.2 Common Product Categories by Application Scenario

Based on downstream application scenarios, waterborne coatings can be categorized into specialized segments such as waterborne coatings for construction machinery, steel structures, shipping containers, and automotive components. The comprehensive range of waterborne industrial coatings launched by Anhui Jindun New Materials Technology Co., Ltd. features tailored formulations optimized for each specific application, enabling direct alignment with the coating requirements of diverse industries.

Instructions for Standardized Construction Procedures of Water-Based Coatings

To fully leverage the performance advantages of water-based coatings, it is essential to adhere to standard application procedures and avoid quality issues in the paint film caused by improper handling. The specific application process can be carried out according to the following standardized steps:

1. Substrate Surface Treatment: Thoroughly remove oil, rust, and dust from the workpiece surface to ensure a clean and dry coating substrate.
2. Paint mixing and dilution: Add purified water according to the product’s recommended ratio, stir for 3–5 minutes until completely uniform, let it stand for 10 minutes, then use.
3. Spray application: Maintain the spray pressure within the range of 0.3–0.5 MPa, and keep the coating thickness between 30 and 50 μm to prevent sagging.
4. Standing and curing: Allow to stand at room temperature for 24 hours to achieve full cure; in low‑temperature, high‑humidity conditions, extend the curing time as needed.
5. Finished‑product quality inspection: Adhesion is assessed using the cross‑hatch test, and the coating surface is visually inspected for defects such as pinholes, blisters, and sagging.

4.1 Precautions for Low-Temperature Application of Waterborne Coatings

For waterborne coatings, the recommended application temperature is above 5°C to prevent abnormal evaporation of moisture at low temperatures, which can lead to issues such as whitening and cracking of the paint film. In cold‑temperature conditions, it is advisable to use additional environmental drying equipment to enhance coating film formation.

4.2 Precautions for the Storage and Handling of Waterborne Coatings

Finished water-based coatings should be stored in an environment with a temperature above 0°C to prevent internal moisture from freezing when temperatures drop below 0°C, which could damage the film-forming polymer structure and render the coating unusable. During storage, prolonged exposure to direct sunlight should also be avoided.

Guideline for Adapting Waterborne Coatings to Common Industrial Applications

Different industrial applications have widely varying performance requirements for coatings. When selecting waterborne coatings, it is essential to align the choice with the specific operating environment of the application in order to balance performance and cost-effectiveness.

5.1 Key Considerations for Selecting Outdoor Steel Structure Scenarios

Outdoor steel structures are exposed to the elements—sunlight and rain—for extended periods. When selecting coatings, prioritize weather‑resistant, color‑fast waterborne acrylic paints paired with a waterborne epoxy zinc‑rich primer; this combination can deliver a service life of 5 to 8 years, meeting the long‑term durability requirements of outdoor infrastructure.

5.2 Key Considerations for Selecting Components in Construction Machinery Applications

Coating for construction machinery components must balance wear resistance, impact resistance, and oil‑and‑grease resistance. We recommend a combination of a waterborne polyurethane topcoat paired with a waterborne epoxy primer; this system delivers excellent overall mechanical performance and meets the demanding requirements of complex operating conditions.

A Summary of Practical Tips to Avoid Pitfalls When Buying Water-Based Paints

Currently, the quality of water-based coatings on the market varies significantly.
