Water-based latex paint has been widely used in modern architectural decoration due to its environmental protection and easy construction. However, its drying speed has always been one of the key factors affecting construction efficiency and coating quality. In order to improve the drying speed of water-based latex paint, c12 film-forming aid, as a high-efficiency additive, plays a vital role.
c12 film-forming aid is a colorless, transparent, high-boiling point oxygen-containing solvent composed of distilled-grade polyester solvents with extremely low odor and excellent resistance to thermal hydrolysis. It can dissolve most resins and has excellent film-forming efficiency, which is significantly higher than traditional alcohol ester twelve. Adding an appropriate amount of c12 film-forming aid to water-based latex paint can significantly affect its drying process, thereby accelerating the drying speed.
C12 film-forming aid mainly improves the drying speed of water-based latex paint through the following aspects:
1. Reduce the minimum film-forming temperature
C12 film-forming aid can effectively reduce the minimum film-forming temperature of latex paint, which means that the paint can also condense into a film faster at a lower ambient temperature. Generally, the drying speed of water-based paint is greatly affected by temperature. The higher the temperature, the more violent the molecular movement and the faster the drying speed. The addition of C12 film-forming aid allows the paint to form a good film at a lower temperature, thereby indirectly improving the drying speed.
2. Improve the film formation process
As a strong solvent for emulsion polymers, C12 film-forming aid is easy to incorporate into the emulsion and does not affect the stability of the paint at a higher content. It can play a lubricating and dispersing role in the film formation process, making it easier for polymer latex particles to aggregate into a continuous and dense film. This improvement helps to reduce the time required for film formation, thereby increasing the drying speed.
3. Promote solvent volatilization
Although c12 film-forming aid itself is a high-boiling point solvent, it will gradually volatilize from the coating after the coating film is formed. This volatilization process helps to remove moisture and other low-boiling point solvents in the coating, thereby accelerating the drying of the coating. At the same time, the volatilization of c12 film-forming aid will not destroy the structure of the coating film, ensuring the final performance of the coating.
4. Optimize the coating formula
By reasonably adjusting the content of c12 film-forming aid in the coating formula, the drying performance of the coating can be further optimized. The right amount of c12 film-forming aid can not only increase the drying speed, but also improve the gloss, strength and anti-powdering performance of the coating film.
In summary, c12 film-forming aid significantly improves the drying speed of water-based latex paint by reducing the minimum film-forming temperature, improving the film-forming process, promoting solvent volatilization and optimizing the coating formula. This improvement not only helps to shorten the construction period and improve work efficiency, but also ensures the quality and performance of the coating. Therefore, the application of C12 film-forming aid in water-based latex paint has broad prospects and important value.
