These products help formulators optimize their product’s performance while being compliant with multiple standards.
Among the products being exhibited are the siloxane-based defoamers AIRASE 5355 and AIRASE 5655, as well as the organic defoamer AIRASE 4655. With regards to wetting agents, Evonik will present the SURFYNOL 355 with especially broad food compliances and the high-molecular-weight TEGO Wet 550.
AIRASE 5355 is a strong siloxane-based defoamer designed to control and quickly eliminate foam without generating defects in water-based coatings, inks, and overprint varnishes. AIRASE 5655 provides excellent compatibility making it the ideal siloxane-based let-down defoamer. As an alternative to siloxane-based additives, AIRASE 4655 is a relatively compatible organic-oil-based defoamer. It is easy to incorporate and provides excellent compatibility with high shear stability. None of these defoamers contain mineral oils, organic solvents, or alkylphenol ethoxylates (APEs).
SURFYNOL 355 surfactant is a substrate wetting additive designed to provide both dynamic and static wetting. It’s the first choice for overprint varnishes, can be easily incorporated into water-based systems, and offers superior wetting for difficult-to-wet substrates. Among the substrate wetting additives, it offers the broadest food contact compliances.
TEGO Wet 550 ensures excellent print results especially on absorbent substrates and exhibits low migration potential due to its high molecular weight.
