MOSCOW (MRC) -- Evonik's Coating Additives business line is expanding its TEGO® Flow series with an efficient polyacrylate-based leveling agent. TEGO® Flow 380 is suitable for solventborne coatings, especially clear coats, said the company.
It is characterized by excellent anti-popping properties and good compatibility. The main applications are automotive and general industrial coatings.
TEGO Flow 380 consists of 100 percent active matter content and is based on a unique polymer technology. “The key here is controlled incompatibility,” explained Maximilian Morin, head of the Industrial & Transportation Coatings market segment.
Some degree of incompatibility with the paint is important for leveling performance, but too much can cause surface defects such as decrease in gloss or haze. “With TEGO Flow 380, we have balanced the incompatibility well, resulting in an excellent performance,” said Morin. In addition, the new leveling agent supports recoatability, which is especially important for automotive refinish applications.
Because of its low viscosity, TEGO® Flow 380 is particularly easy to incorporate into the formulation. “It can be used directly; dilution is not necessary,” said Michael Wang, Applied Research & Technology - Industrial & Transportation Coatings.
In addition, the new product is particularly sustainable: for one thing, it shows excellent performance even at low dosages. For another, the leveling agent emits little VOC (Volatile Organic Compounds), which makes it attractive for high-solids formulations due to its very low viscosity impact.
We remind, Evonik is expanding its capacity to produce MetAMINO (DL-methionine) on Jurong Island, Singapore, by 40,000 metric tons to around 340,000 metric tons per year. The high double-digit million euro investment in this further technological development is to reach target capacity by the third quarter of 2024. The planned process optimization measures will improve the carbon footprint of MetAMINO® produced in Singapore by six percent.
