Evonik has expanded the TEGO® Wet family with two new wetting agents: TEGO® Wet 290 and TEGO® Wet 296.
Evonik's Coating Additives Business Line has recently launched TEGO® Wet 290 and TEGO® Wet 296 - two new wetting agents that can be used for different substrates such as wood, plastic, and metal surfaces. The new wetting agents improve wetting and anti-cratering properties and enhance flow and leveling.
The two additives differ mainly in their composition:
- TEGO® Wet 290 consists of 100% polyether-modified siloxane and is mainly suitable for formulations with requirements of low volatile content.
- TEGO® Wet 296 is a 52% solution of a polyether-modified siloxane in DPM (dipropyleneglycol-methyl-ether), which works well in low solids formulations such as waterborne automotive basecoats.
“TEGO® Wet 296, the diluted version of the additive, is easier to incorporate into the formulation. Since overdosing can cause craters on the surface, it is less prone to defects. Our customers can also dilute the 100 percent version to the level they need, if necessary”, explains Andreas Stüttgen, Manager Applied Research & Technology Transportation Coatings.
Their excellent flow and leveling properties make TEGO® Wet 290 and TEGO® Wet 296 suitable for the automotive industry, where the demand for high-gloss coatings with a unique colour impression continues to grow. TEGO agents are also suitable for the wood industry.
“As a truly global partner to our coating customers, we are constantly working to expand our offering, to meet the evolving market and customer needs”, says Maximilian Morin, head of the Industrial & Transportation Coatings market segment. “With our two new wetting agents, we are trying to help satisfy the appearance requirements for automotive and wood furniture coatings.”
