Application and Development Trend of Plasticizers in Coating Industry

Plasticizers play a key role in the coatings industry similar to the plasticization of plastics. They provide various advantages to coatings by improving the flexibility of the paint film and lowering the film-forming temperature. These chemical magic assistants not only tune the physical properties of paints, but also show a wide range of applications in the field of materials science. This article will deeply explore the common types of plasticizers in the coatings industry and their application characteristics. It will also analyze the internal and external plasticizing methods of plasticizers and look forward to future development trends driven by science and technology.

Application of plasticizers in coating industry

In the coating industry, phthalate plasticizers are one of the common types, among which DOP and DBP dominate the usage. These plasticizers adjust the hardness, modulus, softening temperature and embrittlement temperature of the paint film by reducing the strength of secondary bonds and increasing the mobility of the polymer chains. In addition, aliphatic dibasic acid esters, phosphates, benzene polyesters and alkyl sulfonate plasticizers also play a key role in specific applications.

Plasticizers work primarily by weakening the secondary bonds between polymer molecules, thereby increasing the mobility of the polymer chains. Internal plasticizers are usually added during the polymerization process and have a narrow operating temperature range, while external plasticizers are formed by adding high-boiling point liquids or low-melting point solids to form a solid solution with the polymer. External plasticizers are more widely used in practical applications due to their comprehensive performance and convenient production.

The development trend of plasticizers in the coating industry

With the promotion of scientific research and technological progress, the development of plasticizers has shown a new trend. First, the growing demand for environmentally friendly plasticizers is driving the development of alternatives. Secondly, the versatility of plasticizers is increasingly becoming a focus, with the emergence of innovative products that can both plasticize and improve other properties. In addition, the technology for accurately controlling plasticizing effects is also constantly improving, bringing more possibilities to the coatings industry.

Overall, the application of plasticizers in the coatings industry not only provides a reliable means to improve the performance of coatings, but also promotes continuous innovation in the coatings industry. In the future, with the popularization of green environmental protection concepts and the continuous innovation of science and technology, plasticizers in the coating industry will surely usher in a broader development space, bringing more convenience and diversity to our lives and work.
