Evonik Coating Additives is expanding its TEGO® Rad range of tailor-made silicone acrylates with a unique, radically crosslinkable additive for radiation-curing coatings and inks.

Ideal for excellent wetting and slip with low foaming, the new TEGO® Rad 2330 is designed for use in a wide range of inks and varnish applications as well as clear and pigmented wood coatings.

TEGO® Rad 2330 carries several reactive groups per molecule, ensuring good crosslinking and minimized migration. It consistently shows strong surface tension reduction and anti-crater effect, slip and release, and excellent low foaming.

“There’s high customer demand in the printing inks industry for additives that have high wetting, anti-crater, flow, slip, and release efficacy and lowest possible migration,” says Susanne Struck, Head of Market Segment Inks, EMEA & Global Projects. “Our TEGO® Rad 2330 is a great product offer that addresses the ongoing needs of this important segment.”

Evonik's TEGO® Rad portfolio of silicone acrylates offers formulators a complete toolbox of solutions to ensure top performance in paints and coatings. These additives for radiation-curing inks and coatings can improve flow, levelling, and appearance, prevent cratering and allow formulators to create products with the desired level of slip and flow. Choosing TEGO® Rad products with a higher or lower number will result in a different level of slip and compatibility, allowing more precision in their formulations.

Evonik’s Coating Additives business line has a comprehensive portfolio for radiation-curing inks as well as a wide range of products to enhance high-performing formulations in the automotive, architectural, decorative, marine and other industries.
