Evonik’s Coating Additives business line has launched an environmentally friendly silicone resin, which has been specifically developed for waterborne coatings. This product instantly replaces previous solventborne resins, of which production is partially or completely prohibited in China.

SILIKOFTAL® HTW 3 - Heat-resistant Silicone Resin

The new SILIKOFTAL® HTW 3 is a heat-resistant silicone resin that meets all the requirements of a sustainable formulation. It is free of organic solvents and features a significantly reduced VOC content from production to application.

SILIKOFTAL® HTW 3 is suitable for food contact as part of the external coating. By eliminating critical ingredients, the silicone resin is not classified as hazardous according to GHS.

Unique Combination of Properties

The combination of properties – high performance, ease of handling, and approval for food contact –makes this product unique on the market. 

Customers can enjoy greater freedom when formulating their coatings as SILIKOFTAL® HTW 3 can be combined with numerous pigments and can be used anywhere stoving coatings are used. This also includes, for example, toasters or other household appliances (electrical appliances). The working temperature resistance is 200°C. The high flashpoint of above 90°C offers corresponding benefits for storage and transport.

“In SILIKOFTAL® HTW 3 we offer a product that meets increasingly stringent regulations,” says Maximilian Morin, head of the industrial coatings market segment. “The extensive and vigorous development has paid off and is an excellent example of our efforts to continuously expand our portfolio and offer more sustainable products.”
