New Product Announcement: Insulation Coating Feedstocks

TUESDAY, NOVEMBER 22, 2022


Specialty chemicals company Evonik has recently released a new product line of feedstocks to substantially improve the performance of thermal insulation coatings. The TEGO Therm range includes two microporous silica-based granules and a heat-resistant, silicone-based binder.

According to the company’s release, the new products from its Business Line Coating Additives offer excellent insulation properties and heat resistance, up to temperatures of 250 degrees Celsius (482 degrees Fahrenheit).

Insulation coatings utilizing TEGO Therm products can reportedly reduce energy loss, aid in occupational health and safety and provide protection against corrosion under insulation, increasing the service life of coated items.

TEGO Therm HPG 4000 granules feature larger particles of around 300 micrometers and is characterized by particularly low thermal conductivity at high temperatures. TEGO Therm HPG 6806 features finer particles around 30 micrometers, enabling higher fill levels and ensuring that coatings have smooth surfaces.

Both granules are reportedly highly insulation-effective, offer mechanical stability and are hydrophobic, with their inorganic structure making them non-combustible.

TEGO Therm L 300, a water-based binder, can withstand temperatures of up to 250 C, compared to standard TIC binders at temperatures of 160 C. Evonik reports that, given its excellent adhesion to various substrates, the binder also ensures particularly resilient coatings.

“Conventional insulation systems, such as mineral wool, are often difficult and time-consuming to apply – appliances and components with complex geometries in particular are often inadequately insulated,” said Dr. Niko Haberkorn, Head of Thermal Managing Coatings at Evonik Coating Additives.

Haberkorn added that, as a result, non-insulated, hot surfaces increase energy loss and need to be protected against accidental contact. However, coatings incorporating the TEGO Therm line can reportedly be easily applied by spraying.

“That is even feasible to some extent during ongoing operations. This avoids equipment downtimes and saves time and money,” he said.

Products from the TEGO Therm line can be combined with one another and with other product lines, depending on the specific application. Coating experts are reportedly available to provide customers with sample formulations incorporating the two granulates for different applications.

“We recommend combining the granulates with the heat-resistant binder from the TEGO Therm line, especially for applications involving very high temperatures,” said Markus Hallack, Head of Applied Research for Thermal Managing Coatings.

The target application for these feedstocks is reportedly for the technical insulation of pipelines, tanks or other components in industrial plants. Evonik hopes to use this product range in the future in the construction and vehicle manufacturing sectors.

Products in the line are currently available worldwide.
