The new additive developed by Evonik provides slip and scratch resistance as well as defoaming and hydrophobicity for UV and UV-LED curing coatings.
The Coating Additives business line of Evonik
has expanded the TEGO® Rad range of tailored silicone acrylates with TEGO Rad 2550, a new clear and low viscosity liquid cross-linkable additive that effectively reduces static and dynamic surface tension in both conventional UV- and LED-cured formulations.
Acrylated products allow to minimise migration and obtain very pronounced and long-lasting effects. The new additive for radiation-curing paints, coatings and printing inks provides also a low coefficient of friction (COF), high scratch resistance, good defoaming and the ability to create hydrophobic surfaces. Moreover, it ensures improved flow and levelling and optical appearance and prevents cratering. Finally, it allows formulators to create products with the desired level of slip and flow and compatibility.
“Due to its unique property profile, TEGO Rad 2550 is truly an excellent additive for the formulation of matte coatings, pigmented inks and roller-applied wood top-coats. It offers a tailored cross-linkable performance. For inks and coatings formulators, this means great long-term effectiveness in the final product, high resource-efficiency and a sustainable solution compared to alternative technologies,” has stated Courtney Thurau, the head of the global market segment for printing inks of Evonik.
