3. Application of DMEA in paint

The application of DMEA in paint is mainly reflected in the following aspects:

3.1 Neutralizer

DMEA can act as a neutralizer to adjust the pH value of the paint to keep it within a suitable range, thereby improving the stability and construction performance of the paint.

3.2 Catalyst

DMEA can be used as a catalyst to accelerate the curing process of paint, shorten drying time and improve production efficiency.

3.3 Surfactant

DMEA can be used as a surfactant to improve the wetting and dispersion of paint, so that pigments and fillers are evenly distributed in the paint film, and improve the uniformity and gloss of the coating.

4. Mechanism to improve paint adhesion

The adhesion of paint refers to the bonding force between the coating and the substrate. Good adhesion prevents the coating from peeling and blistering, extending the life of the coating. DMEA improves the adhesion of paint through the following mechanisms:

4.1 Improve wettability

As a surfactant, DMEA can reduce the surface tension of the paint and improve its wettability to the substrate. The improvement of wettability allows the paint to penetrate better into the micropores of the substrate, enhancing the mechanical bonding of the coating to the substrate.

4.2 Enhanced chemical bonding

The amine group in DMEA can react chemically with functional groups such as hydroxyl groups and carboxyl groups on the surface of the substrate to form chemical bonds. This chemical bond is stronger than pure physical adsorption, significantly improving the adhesion of the coating.

4.3 Adjust pH

DMEA, as a neutralizer, can adjust the pH of the paint to match the surface charge of the substrate. Adjusting pH value can reduce electrostatic repulsion between the coating and the substrate and enhance the bonding force between the two.

5. Mechanism for improving paint weather resistance

Weather resistance refers to the ability of the coating to resist natural factors such as ultraviolet rays, humidity, and temperature in an outdoor environment. DMEA improves the weather resistance of paints through the following mechanisms:

5.1 Antioxidant effect

The amino groups in DMEA have antioxidant effects, which can capture free radicals and prevent oxidative degradation of resins and pigments in paint. The enhanced antioxidant effect can extend the life of the coating and maintain its color and luster.

5.2 Anti-UV rays

DMEA can absorb ultraviolet rays and reduce the damage to paint by ultraviolet rays. Ultraviolet rays are one of the main factors that cause coating aging. The anti-ultraviolet effect of DMEA can effectively delay the aging process of the coating.

5.3 Adjust moisture balance

DMEA can adjust the moisture balance in the paint to prevent the coating from cracking, peeling and other problems due to excessive or too little moisture. Adjustment of moisture balance can improve the stability and durability of the coating.

6. Product parameters and performance

The following are typical product parameters and performance of DMEA in paint:

6.1 Product parameters

7. Practical application cases

7.1 Building exterior wall coating

Adding DMEA to building exterior paint can significantly improve the adhesion and weather resistance of the coating. After practical application testing, after 5 years of use in outdoor environments, the coating remains intact without obvious peeling or fading.

7.2 Automotive Paint

Adding DMEA to automotive coatings can improve the coating’s UV resistance and oxidation resistance. After practical application tests, after 3 years of parking outdoors with DMEA, the color and gloss of the coating remained good, and there was no obvious sign of aging.

7.3 Furniture paint

Adding DMEA to furniture coatings can enhance the adhesion and wear resistance of the coating. After practical application tests, after 2 years of use, the coating has no obvious wear or peeling of the furniture paint with DMEA, and maintains a good appearance.

8. Conclusion

DMEA dimethylamine, as a multifunctional additive, has significant advantages in the application of paint. Through mechanisms such as improving wettability, enhancing chemical bonding, and adjusting pH, DMEA can effectively improve the adhesion of paint. Through mechanisms such as antioxidant, anti-UV rays, and regulating moisture balance, DMEA can significantly improve the weather resistance of paints. Practical application cases show that the paint with DMEA has a wide range of application prospects in the fields of construction, automobile, furniture, etc.

Rational use of DMEA can significantly improve the performance of paint, extend the service life of the coating, and reduce maintenance costs. I hope that the introduction of this article can provide valuable reference for practitioners in related fields.
