TEGO Wet 570 Terra and TEGO Wet 580 Terra are specifically designed for use in waterborne coatings and inks.
Evonik Coating Additives is launching biosurfactants specifically designed for coating and ink formulations. The two new products, TEGO Wet 570 Terra and TEGO Wet 580 Terra, are set to transform the paints, coatings and inks industry by combining high performance with an exceptional sustainability profile.
These biosurfactants are produced by microorganisms in a unique fermentation process. Unlike fossil-based surfactants, they are 100% derived from natural resources. Besides having very low levels of volatile organic compounds (VOCs), their natural origin makes them readily biodegradable and well tolerated by aquatic organisms. TEGO Wet 570 Terra and TEGO Wet 580 Terra are specifically designed for use in waterborne coatings and inks.
“With our TEGO Wet 570 Terra and TEGO Wet 580 Terra, we offer our customers completely new high-performance solutions that also drive the green transformation in the paint and coatings industry,” said Elias Lacerda, head of Coating Additives at Evonik.
Their fast wetting of pigments and fillers leads to reduced grinding time and energy consumption, resulting in energy savings and efficient production processes for customers.
“Our TEGO Wet 570 Terra and TEGO Wet 580 Terra are suitable for waterborne decorative paints, industrial and transportation coatings and inks,” noted Katina Kiep, head of decorative coatings at Evonik Coating Additives. “Their unique properties and the fact that they meet the stringent standards of the EU Ecolabel make them an ideal choice for our customers to formulate coatings for a sustainable future.”
The majority of these biosurfactants are produced in Slovakia.
“These new products not only demonstrate our strong innovation capabilities, but also our commitment to driving positive change in the development of environmentally friendly solutions and setting new standards for additives in the coatings and inks industry,” added Tim-Frederic Sloot, head of sustainability at Evonik Coating Additives.
Benefits for Decorative Coatings
In decorative paints and pigment concentrates, these biosurfactants provide improved wetting of organic and inorganic pigments and act as beneficial co-dispersants. They improve the wetting speed of pigments and fillers, making the grinding step more efficient and reducing time and energy consumption. They support good hiding power performance without compromising film strength. They also help eliminate defects in sensitive binders and increase bio-based content. There is no negative interaction with rheology modifiers.
Benefits for Industrial Coatings
In industrial coatings, TEGO Wet 570 Terra and TEGO Wet 580 Terra provide excellent substrate wetting for protective coatings and improve pigment wetting and dispersion. They ensure optimum colour properties, improved storage stability and good corrosion resistance. These biosurfactants also support the anti-crater effect in can coatings.
Benefits for Printing Inks
In printing inks, these biosurfactants improve wetting on a variety of substrates. In the dispersion process they speed up and improve the wetting of pigments and fillers. They contribute to the sustainability profile of the inks by reducing VOC levels and improving the biodegradability of the final product.
