New Product Announcement: Defoamer Slip Additive


Specialty chemicals company Evonik recently announced the release of a new crosslinkable defoaming slip additive for ultraviolet- and LED-cured formulations. TEGO Rad 2250 is a clear, low viscosity liquid that effectively reduces static and dynamic surface tension.

According to the release, key attributes of the additive include low coefficient of friction, high scratch resistance, good defoaming and the ability to create hydrophobic surfaces.

“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,” said Courtney Thurau, Head of Evonik’s Global Market Segment for Printing Inks.

An expansion of the TEGO Rad portfolio of silicone acrylates, these additives can reportedly improve the flow and leveling and optical appearance, prevent cratering and allow formulators to create products with the desired level of slip and flow.

Additionally, Evonik notes that the use of TEGO Rad products with a higher or lower number will result in a different level of slip and compatibility, allowing for precision in formulations.

“TEGO Rad products offer 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,” said Thurau.
