Organic silicon leveling agents have significant advantages in the coatings and ink industries due to their unique chemical structure and properties. The following are their main characteristics and advantages:
1. Significantly reduce surface tension
Organic silicon leveling agents can significantly reduce the surface tension of coatings, thereby improving the wettability of coatings on substrates and reducing the occurrence of surface defects such as shrinkage and ripples. This characteristic makes the coating easier to spread and flow during the coating process, forming a more uniform and smooth coating film.
2. Excellent migration performance
Organic silicon leveling agents have excellent migration properties and can quickly migrate to the surface of the paint film, forming an extremely thin monolayer. This layer of film not only further reduces surface tension, but also slows down the solvent evaporation rate, prolongs the leveling time of the wet film, and thus achieves better leveling effect.
3. Enhance physical performance
Organic silicon compounds themselves have excellent waterproof, thermal stability, and weather resistance. After adding organic silicon leveling agent, the coating can better maintain its performance and appearance when in contact with water, and can also remain stable under high temperature or harsh weather conditions. These characteristics help to extend the service life of the coating and improve the durability of the coating.
4. Improve glossiness and appearance
By reducing surface tension and improving leveling properties, organic silicon leveling agents can significantly enhance the glossiness and smoothness of coatings, making the coating surface smoother and brighter. In addition, it can also eliminate surface defects such as Benel vortices, preventing the formation of flowers and orange peel.
