ESSEN, GERMANY: Evonik has recently launched two new substrate wetting additives, TEGO Wet 285 and 550, which were specifically developed for printing on food packaging.
With the new technology, both products have a very high molecular weight for substrate wetting additives, which results in a particularly low tendency to migrate. This prevents the substances from penetrating the packaging and reaching the food. TEGO Wet 285 and 550 also comply with the Swiss Consumer Goods Ordinance (Annex 6, List A), which governs the use of substances used for printing of food packaging.
And with its excellent substrate wetting properties, TEGO Wet 550 enhances process reliability and achieves high-quality printing results. The pronounced reduction of surface tension that can be achieved in particular with TEGO Wet 285, paired with low foam stabilising, enable the easy wetting of demanding substrates, such as films. TEGO Wet 550 is particularly suitable for use on paper.
Both products are solvent-free and liquid, which translates into easy handling for formulators in production and in the laboratory.
"TEGO Wet 285 and 550 are among the first high molecular weight substrate wetting additives on the market. The combination of low migration tendency and conformity with the ‘A’ list of the Swiss Ordinance offers our customers a trend-setting formulation approach," said Thorsten Schierle, director of applied technology inks, digital & new applications.
