HEGGEL Flake stands for low-diffusion, chemically and thermally resistant synthetic resin coatings, which are enriched with glass flakes (wafer-thin, micro-fine, transparent glass flakes). Glass flakes are lamellar barrier pigments that line up parallel to the substrate. In this way, an excellent barrier effect is created which makes the penetration of moisture, gas and chemicals considerably more difficult and thus ensures a long lifetime of the coating. HEGGEL Flake coating systems are mainly used in chimneys, gas preheaters, heat exchangers or gas ducts in flue gas desulphurisation plants.

In addition, HEGGEL Flake offers high dry temperature resistance, outstanding adhesion to steel and high abrasion resistance.

HEGGEL Flake products are self-priming single or multi-layer systems, with extreme adhesion to concrete and steel.

HEGGEL Flake systems are applied by airless-spraying, brushing or rolling.

HEGGEL®️  Flake 710

Glass Flake Filled Novolac Vinyl Ester Resin

HEGGEL Flake 710 is a two-component; vapour diffusion resistant, inert flake filled polymer coating based on a chemical and thermal resistant Novolac vinyl ester resin. HEGGEL Flake 710 is the ideal corrosion protection if high chemical resistance is required at high medium temperatures. The parallel to the substrate oriented inert flakes provide an excellent diffusion barrier and thus ensure a long service life.


  • High temperature stability up to +180°C
  • Excellent permeation resistance
  • Excellent chemical resistance to inorganic and organic acids, alkalines and organic solvents
  • Outstanding adhesion to steel
  • Application by spraying, brushing or rolling
  • Can be exposed to process conditions shortly after application

HEGGEL®️  Flake 730

Anti-Corrosion Glass Flake Epoxy Coating

HEGGEL Flake 730 is a high solids two-component epoxy containing micronized glass flake and anti-corrosive pigments.


  • Excellent abrasion resistance
  • Excellent resistance to immersion in sea water and a range of chemicals
  • Compatible with cathodic protection.

HEGGEL®️  Flake 770

Epoxy Novolac Vinylester Glass Flake Coating

HEGGEL Flake 770 is a specialized spray coating based on Epoxy Novolac Vinylester containing unique glass flake barrier fillers. The spray application aligns the barrier fillers parallel to the substrate, ensuring exceptional resistance to water vapor diffusion and permeation.


  • Exceptional diffusion resistance
  • High chemical resistance
  • Temperature resistance up to 80°C (immersed) and up to 200°C (non-immersed)
