TEGO Flow 375 and TEGO Flow 460 N from Evonik are two new silicone-free flow and levelling additives specifically developed for use in can and coil coatings. Both products are listed worldwide and are suitable for direct contact with food (FDA 175.300). This reduces complexity for coatings manufacturers and enables broad use. Instead of using many different products, manufacturers can use the same additive for more diverse end-uses.
Both additives make an impressive contribution to meeting the high demands made on the global production and marketing of can and coil products. End-users’ decisions are strongly influenced by quality considerations and appearance.
"Both products are silicone-free. Impurities and associated cratering can, therefore, be excluded, thus ensuring smooth-running production”, explained Kirstin Schulz, Marketing Director for industrial coatings. In addition, the flow and levelling additives exhibit improved heat resistance and give the coating a durable, high-quality appearance.
TEGO Flow 375 is especially compatible in solvent-based formulations and achieves optimum gloss values.
TEGO Flow 460 N also possesses de-aerating characteristics, thus enabling defect-free application especially in pigmented formulations. Very good adhesion and wetting properties in multi-coat finishes enable both products to be used in all the coats without impairing the painting process. Both additives are free from aromatics.
