Enhance Metal Protection and Adhesion with High-Performance Conversion Coating Solutions
Product Description
Conversion Coating is a specialized chemical or electrochemical treatment applied to metal surfaces to create a thin, adherent layer of metal compound. This layer is designed to improve the metal's performance by enhancing corrosion resistance, promoting adhesion for subsequent coatings, and sometimes providing lubricity. Conversion coatings are commonly used as a critical step in surface preparation before painting, powder coating, or electroplating, ensuring long-lasting and durable results.
This process is highly effective on a variety of metals, including aluminum, steel, zinc, and magnesium alloys, making it a versatile solution for industries ranging from automotive and aerospace to construction and electronics.
Key Features
Provides an additional protective layer that shields metal surfaces from rust and oxidation, extending their service life.
Improves the adhesion of subsequent coatings, such as paints, powder coatings, or lacquers, ensuring a smooth and uniform finish.
Modern conversion coatings often use low- or non-toxic formulations, reducing environmental impact.
Compatible with various metals and suitable for multiple applications, including phosphate, chromate, and zirconium-based coatings.
Certain conversion coatings allow for electrical conductivity, making them suitable for specific electronic applications.
Available in different formulations tailored to meet specific performance requirements, such as additional wear resistance or reduced friction.

Support and Services
We will provide the following technical support and services for all products under the Jingtu Paint brand.
1. What types of metals are compatible with your Conversion Coating solutions?
Our Conversion Coating solutions are compatible with a wide range of metals, including aluminum, steel, galvanized steel, and magnesium. Each formulation is tailored to ensure optimal adhesion, corrosion resistance, and surface preparation for subsequent coatings.
2. How does your Conversion Coating improve corrosion resistance for metal substrates?
The Conversion Coating forms a chemically bonded layer on the metal surface, which acts as a protective barrier against environmental factors such as moisture, oxygen, and chemicals. This barrier enhances the metal’s resistance to rust and corrosion over time.
3. Can your Conversion Coating be used in automated production lines?
Yes, our Conversion Coating is highly adaptable and can be integrated into automated production lines. It supports spray, dip, or roll-coating application methods, making it suitable for high-efficiency industrial processes.
4. What are the typical drying times for your Conversion Coating solutions?
The drying times vary depending on the specific product and environmental conditions. On average, our Conversion Coating solutions dry within 10–30 minutes at room temperature or can be accelerated using low-temperature ovens.
5. Does your Conversion Coating enhance paint adhesion, and how is this measured?
Yes, our Conversion Coating significantly enhances paint adhesion by creating a textured surface that promotes bonding. This is measured through adhesion testing methods such as cross-hatch or pull-off tests, ensuring strong and durable coatings.
6. Are your Conversion Coatings suitable for high-temperature applications?
Yes, certain formulations of our Conversion Coatings are specifically designed to withstand high-temperature environments, maintaining their protective properties and adhesion performance under thermal stress.
7. What pretreatment process is required before applying the Conversion Coating?
The metal surface should be thoroughly cleaned and degreased to remove oils, dirt, and contaminants. In some cases, additional surface preparation like acid pickling may be recommended to ensure optimal coating performance.
