SONGWON Presents New Water-Based Stabilizers for Coatings and Functional Monomers for Resins

Present at the ECS for the second time, SONGWON Industrial Co. Ltd. is introducing an expanded range of specialty chemicals.
Present at the ECS for the second time, SONGWON Industrial Co. Ltd. is introducing an expanded range of specialty chemicals.
The WB product range is a group of water-miscible products that have been developed to meet the increased demand for environmentally acceptable additives.
“The new light stabilizers and antioxidant combine the efficiency of conventional products with the benefits not only of water miscibility and low-to-zero VOC generation, but also of easy dosing and handling,” explained Rosanna Telesca, Leader of the Market Center Coatings.

The range includes two UV absorbers, an antioxidant and a hindered amine light stabilizer (HALS). Songsorb CS 326 WB UV absorber, which is based on benzotriazole, is suitable for waterborne industrial, architectural, decorative and wood coatings, while triazine-based Songsorb CS 400 WB can also be used for more demanding applications such as automotive coatings. Water-compatible phenolic antioxidant Songnox CS 2450 WB is designed particularly for polyurethane-based coatings. Together with the water-compatible HALS Songsorb CS AQ01, which was introduced at the last ECS, these products provide a synergistic stabilization package for water-based coating systems. The products can be used together as required. “It is all a question of achieving the right balance for the respective application,” said Ms. Telesca.
The company’s team of specialty chemicals experts is currently working to expand the newly introduced WB range still further.
SONGWON is also introducing its new functional monomers at the Show. The first two ranges are now available and a third line is under development.
“Functional monomers are specialty molecules that can provide a standard polymer with additional, enhanced performance effects such as soil repellency, and/or significantly improve processing performance,” said Heiner Schulte, Leader of the Market Center Functional Monomers. “We work very closely with our customers, developing the products together with them in order to meet their needs.”
ERM-6100 is the latest addition to SONGWON’s range of dicyclopentadiene (DCPD) phenol resins. These monomers are mainly used during the manufacture of epoxy composites as epoxy resin modifiers (ERMs) in epoxy chain-extending reactions and as hardeners. The new monomer, which combines high functionality with low viscosity, says Heiner Schulte, has been developed especially for electronic applications and high-performance resins such as polybenzoxazine (PBO). With their different softening points, functionality and viscosity, the five products in the range cover a wide variety of requirements.

SONGWON has also added two bisphenol (BP) monomers to its portfolio. BP-TMC is used to modify epoxy resins as well as non-optical polycarbonate and polyester polymers. It is distinguished by its cost efficiency and good chemical purity. TMBP, which is suitable for both epoxy and phenolic resins, is designed to ensure the highest purity and excellent color, and it gives the resin a high glass transition temperature. More BP grades, currently being scaled up, are available in pilot quantities.
