Tego Flow 375 and Tego Flow 460 N from Evonik are two new silicone-free flow and leveling 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 products are silicone-free,” said Kirstin Schulz, marketing director for industrial coatings. “Impurities and associated cratering can therefore be excluded, thus ensuring smooth-running production In addition, the flow and leveling additives exhibit improved heat resistance and give the coating a durable, high-quality appearance.” Tego Flow 375 is especially compatible, she added, in solvent-based formulations and achieves optimum gloss values. Tego Flow 460 N also possesses deaerating characteristics, thus enabling defect-free application especially in pigmented formulations. Their adhesion and wetting properties in multi-coat finishes enable both products to be used in all the coats without impairing the painting process. Tego Flow 375 and Tego Flow 460 N are free from aromatics.   www.tego.de
