International. Foam in wood coatings can result in a loss of transparency and protection, and can also adversely affect the overall optical appearance, feel, and even production efficiency.
Evonik's coating additives business line adds a new deaerator to its portfolio. Specially designed for radiation-cured wood coatings, the new deaerator, TEGO Airex 923, is a highly compatible 100% active organic polymer that shows improved efficiency.
UV-curable coatings have many advantages: they are eco-friendly, almost universally applied, and have a very fast, efficient and productive application process. However, this type of coating system also has foaming problems.
Depending on the specifics of the formulation and the choice of application conditions, Evonik offers defoamers and deaerators with a variety of application profiles.
With TEGO Airex 923, Evonik is adding an effective deaerator for radiation curing of wood coverings and furniture.
TEGO Airex 923 breaks down foam quickly and efficiently preventing air inclusions and pores from forming.
This is particularly important in high-viscosity or high-solids formulations where the concentrate provides excellent compatibility.
It can be used with multiple types of binders and many different ingredients.
The polymer character and good compatibility of the product lead to excellent coating capacity and make TEGO® Airex 923 suitable even for transparent layers with the highest demands on optical appearance.
Foam in wood coatings can result in a loss of transparency and protection, and can also adversely affect the overall optical appearance, feel, and even production efficiency.
TEGO Airex 923 solves these problems and is very easy to use. The degasser shows good flow behavior, which makes it easy to handle. It can be stored for a longer period and shows an equally high performance afterwards.
