One highlight is the newly developed TEGO Foamex 9, a mineral-oil-based defoamer with long-term effectiveness and good compatibility with the coating.
It can be incorporated during the grind or let-down stage.
The new defoamer rounds off Evonik’s portfolio of siloxane defoamers, allowing the customer to choose the technology that is the best fitting for their formulations.
This advantage is particularly important for coatings that come in huge quantities. Furthermore, customers have the chance to replace their currently used mineral oil defoamers more easily with this new grade. Besides architectural paints, TEGO Foamex 9 can also be used in pigment concentrates.
Also, Coating Additives is highlighting three new cost-effective dispersing additives, all of which are suitable for inorganic pigments and fillers. TEGO Dispers 711 W and 717 W are sodium salt polyacrylates with different molecular weights, and TEGO Dispers 712 W is an ammonium salt polyacrylate. All three products offer good dispersibility and viscosity reduction as well as improved color acceptance.
