Evonik Launches New Heat Stable Hardener

The new TEGO Cure 100 hardener from Evonik ensures that the coating cures at room temperature. This eliminates the need for costly and energy-intensive drying in the oven. At the same time, the surface is heat-stable up to 650°C during application.

TEGO Cure 100 was specially developed for surfaces that are continuously exposed to high temperatures, such as ovens, pipes, or machines that become very hot during opera-tion. The hardener is suitable for silicone resins as well as silicone combination resins and offers a whole range of other advantages. The hardener improves the corrosion protection of the coating, especially when it is under an insulating layer. In addition, the high solids content of more than 99% reduces solvent emissions to a minimum.

“Our new hardener meets the ever-increasing regulatory requirements,” said Maximilian Morin, head of the Industrial & Transportation Coatings market segment. “We are con-vinced that the new hardener will be a future-proof component in our customers’ formu-lations.”

The new silicone resin-based hardener is particularly suitable for direct-to-metal coatings, allowing costly multi-layer build-ups to be avoided.
