Industrial coatings

The improvement of water-based coatings' performance also enables them to be used in a wider range of applications, which are traditionally based on solvent based coatings.OSiC began to see that waterborne coatings have competitive or better performance in light applications, although it is generally believed that waterborne coatings do not achieve the performance of solvent based systems. Water based systems for heavy duty applications are also making progress.

The progress of additive technology is very important for the development of high performance waterborne coatings. The high surface tension of water requires specially designed additives to ensure the best performance in the production and application process and the film. At the same time, the physical properties of water make the control characteristics necessary and challenging, such as defoaming, fluidity and leveling, covering, scratch resistance and adhesion resistance.

Additives, especially multifunctional materials, overcome the surface tension obstacle and the formation of large / Micro Foam, so that waterborne coatings can achieve the same performance as solvent based systems. New dispersant technology can achieve better color development and even provide functional properties such as water resistance. At the same time, advances in rheological modifiers have enabled formulators to develop coatings with performance characteristics such as one coat coverage, smooth surface and uniform appearance and color. These surfactants can provide higher performance standards for early water resistance, adhesion and durability of waterborne coatings and elastomers.
