On the application of triacetin in coatings
Triacetin is widely used in the field of coatings. Because of its many specific properties, the cover can make the coating perfect.
Looking at its solubility, triacetin can dissolve many resins, such as cellulose esters. This characteristic makes the coating preparation, the ingredients can be evenly miscible, and the texture after film formation is uniform, without mottling. Applied to the surface of the utensils, the coating is smooth, the color is uniform, and the beauty is born.
And its plasticizing properties can greatly increase the flexibility of the coating. When the coating is bent and vibrated by external forces, it is not easy to crack. In the coating of daily necessities, such as wooden furniture and metal jewelry, it can effectively resist environmental stress, prolong the service life of the utensils, and last for a long time.
In addition, triacetin has a good volatile control effect. During the drying process of the coating, its volatilization rate is moderate. If it is too fast, the coating is prone to pinholes, orange peel and other defects; if it is too slow, it takes a long time to dry, which affects the production efficiency. Moderate volatilization rate ensures a smooth drying process of the coating, and finally forms a dense and defect-free protective film, which enhances the protective ability of the coating against utensils.
In addition, its chemical stability is also key. In the coating system, it does not react adversely with other components, and can maintain the stability of the chemical structure of the coating for a long time. Even in complex environments, such as high humidity and chemically corrosive media, the coating can still adhere to its protective and decorative functions.
In summary, the application of triacetin in coatings, with its solubility, plasticity, volatilization control and chemical stability, contributes greatly to the improvement of coating performance, and is an indispensable and important substance in the coating field.
