New product group of high-performance granules and heat-resistant binder for thermal insulation coatings
BENEFITS AT A GLANCE:
Easy to apply via spray process
Large areas & complex shapes can be insulated in a short time while equipment is still in service
TIC provides direct protection of substrate and condensation control
Ideal technology for personnel protection
TIC reduces temperature of hot surfaces and prevents skin burns if touched
TEGO® Therm makes insulation coatings more efficient
The three new products from Evonik’s Coating Additives business line are characterized by excellent insulation properties and heat resistance, even at temperatures of up to 250°C. This provides the following performance and sustainability benefits for use in the engineering, marine, and construction sectors.
Insulation coatings based on TEGO® Therm products substantially reduce energy loss and contribute to occupational health and safety, as they can significantly reduce the temperature of hot surfaces. They also provide protection against moisture penetration and therefore prevent corrosion under insulation (CUI), which can significantly increase the service life of coated items.
In contrast to conventional insulation systems, such as mineral wool, insulation coatings are easy to apply on complex 3D shapes via spray application, and can also be applied during ongoing operations, giving the benefit of dramatically reducing downtime and maintenance costs.

The new TEGO® Therm products in detail
The two microporous composite granules TEGO® Therm HPG 4000 & TEGO® Therm 6806 are non-combustible, high-performance thermal insulation materials. They combine excellent insulation values with fire protection and sustainability. Both grades are pure minerals based on a proprietary fumed silicon dioxide composite, which does not contain flame retardants based on halogens or heavy metals.TEGO® Therm HPG 4000 granules are characterized by an average diameter of approx. 300 µm and contain a special IR passivation component for excellent insulation performance at high temperature ranges.
TEGO® Therm HPG 6806 consists of finer particles of approx. 30 µm which enables the formulation of coatings with smooth surfaces.
The product range is complemented by a water-based binder TEGO® Therm L 300 that can withstand temperatures of up to 250°C. Standard binders for TICs can only withstand temperatures no higher than 160°C. Given its excellent adhesion to various substrates, TEGO® Therm L 300 ensures excellent mechanical properties at high temperatures as well excellent compatibility to extend the temperature resistance of conventional acrylic-based systems.
These products offer new solutions to long-standing issues in the areas of energy efficiency, safe-touch, and condensation control.
Figure 2: TEGO® Therm benefits at a glance
Personnel protection and safe-touch
When incorporated into a safe-touch coating system, the thermal insulating TEGO® Therm granules help prevent contact burns and provide the product flexibility needed to effectively cover potentially complex surfaces. The use of TEGO® Therm HPG 4000 & TEGO® Therm 6806 shows outstanding long-term performance in this application compared to other industry-used particles, with the thermal protection being active and reliable for several years.Corrosion under insulation (CUI)
When dealing with corrosion sensitive surfaces, most of the potential benefits can be achieved by using a heat-stable, ambient-curing primer and a following insulative coating layer based on TEGO® Therm components. This combination shows excellent resistance to heat flow, combined with the perfect protection against corrosion under insulation (CUI).Condensation control
When surface temperatures drop below the dew point, condensation forms and damage due to moisture is soon to follow. Coatings based on hydrophobic and thermal insulative TEGO® Therm components have the potential to dramatically change the temperature profile of the substrate they are applied to, keeping coating surface temperatures above the point where water will condense.The new product group of TEGO® Therm offers several essential advantages to our customers:
- Easy to apply via spray process
- Large areas & complex shapes can be insulated in a short time while equipment is still in service
- TIC provides direct protection of substrate and condensation control
- Ideal technology for personnel protection
- TIC reduces temperature of hot surfaces and prevents skin burns if touched
- Increased facility lifecycle
