Heat Resistant Coatings

Extreme temperatures demand coatings that are not compromised. From industrial powerhouses like mufflers to consumer favorites like cookware, Evonik delivers advanced additives and resins for heat-resistant coating systems.

Whether you’re formulating for waterborne or solventborne systems, our solutions help you address heat resistance, corrosion protection, adhesion and surface appearance.

High-temperature resistant coatings for exhaust systems, industrial ovens, grills and combustion chambers must retain corrosion protection and weather resistance while meeting high demands on thermal stability. Such coatings are normally applied to steel at dry film thicknesses of 20–25 µm.

• Proven Expertise: Trusted brands like ACEMATT®, SURFYNOL®, TEGO® cover matting, wetting, rheology and insulation functions in heat-resistant systems.
• Waterborne Options: TEGO® Therm L 300 is a waterborne silicone hybrid binder with a solid content of approximately 50 %, broad compatibility with acrylic emulsions and ambient film forming. SILIKOPHEN® P 80/X is suitable for low-VOC formulations.
• Tailored Performance: From mufflers and fireplaces to cookware and industrial equipment, our solutions adapt to your toughest challenges.

Industrial Equipment & High-Temperature Components

• TEGO® Therm – Advanced components for thermal insulation coatings, comprising microporous silica-based granules and a waterborne heat-resistant binder. TEGO® Therm HPG 4000 has a particle size d50 of approximately 300 µm with low thermal conductivity and high hydrophobicity; TEGO® Therm HPG 6806 has a d50 of approximately 30 µm and allows easier incorporation with less thickening.
• TEGO® Viscoplus – Rheology modifiers for optimal application and stability under heat stress.
• VPS 4721 – A versatile adhesion promoter and crosslinker that chemically links organic polymers to inorganic surfaces in heat-resistant coatings and adhesives.
  

Decorative & Functional Finishes

• ACEMATT® – Matting agents for, heat-resistant surfaces with an aesthetic finish.
• SURFYNOL® – Wetting agents that enhance substrate adhesion and coating uniformity.

Performance Additives for Waterborne & Solventborne Systems

• TEGO® Wet, TEGO® Dispers, TEGO® Airex, TEGO® Cure – Complete additive portfolio for improved wetting, dispersion, and curing in heat-resistant coatings.

• Extreme Heat Resistance: SILIKOPHEN® silicone resins provide long-term heat stability of up to 650 °C when formulated with metallic pigments and suitable formulations. Insulation coatings based on TEGO® Therm components offer heat resistance at temperatures of up to 250 °C.
• Corrosion Protection & Aesthetics: SILIKOPHEN® resins provide corrosion protection and are used in ovens, grills, mufflers, exhaust coatings and industrial facilities such as pipelines.
• Expert Support: Our specialists partner with you to optimize formulations for performance.
