Bio-defoamer with EcoLabel: The new all-rounder for architectural paints

  • Based on 98% renewable resources
  • Meets the requirements of all relevant EcoLabel
  • Good balance between efficacy and compatibility

The "bio-based" feature is not all that goes into making a good defoamer. In fact, the demands on good defoamers in the architectural sector are numerous: the additive must be well-tolerated, meet EcoLabel standards, be as widely applicable as possible, and of course, it must reliably prevent foam formation. The new defoamer TEGO® Foamex 18 from Evonik meets these requirements.

TEGO® Foamex 18 enriches the already extensive defoamer portfolio of the Coating Additives business line and adds a unique property profile: The new defoamer consists of 98% vegetable oil – a renewable raw material. TEGO® Foamex 18 is the first bio-based defoamer from Evonik specifically developed for the architectural market. "The trend towards sustainable formulations is unbroken in the market," says Nadia Lenhardt, Head of Market Segment Decorative Coatings, EMEA. "Our additives for water-based formulations have been in use for decades. The new bio-based additive is a consistent next step in our efforts to enable sustainable formulations for bio-based paints".

TEGO® Foamex 18 shows a very good balance between efficacy and compatibility. It is also easy to process and suitable for both grind and let-down stages. All in all, the defoamer is universally applicable and thus equally suitable for a wide range of formulations. The additive also meets the requirements of all relevant EcoLabels such as the Blue Angel and EU Ecolabel.

By continuously expanding the existing defoamer portfolio not only in the architectural sector, but also for industrial, automotive, and printing ink applications, Evonik Coating Additives offers the best possible solution for almost any desired formulation.
