Anti-Corrosive Coatings

WACKER provides binders and additives for the formulation of high-quality primers and coatings for corrosion protection that withstand even very harsh environmental conditions.

Zinc-rich paints based on ethyl silicates combine outstanding, long-term corrosion protection of ferrous surfaces with resistance to high temperatures. Typical application areas are bridges, ships and structural steel exposed to severe weather and chemicals.

Primers and Corrosion-Protection Paints

VINNOL® surface coating resins containing carboxyl groups are ideal for formulating primers and corrosion-protection paints.


  • Excellent metal adhesion
  • High resistance to acids, alkalis and salt solutions
  • Good pigment wetting
  • Low water absorption

Zinc-dust Coatings, Primers and High-Build Paints

WACKER ethyl silicates are proven binders for the formulation of high-quality zinc-dust coatings for shop primers, primers and high-build paints. HDK® pyrogenic silica is used as an additive for improved handling and rheology control.

Benefits of WACKER Ethyl Silicates:

  • Improved corrosion protection
  • Good weldability
  • Rapid curing at low temperatures
  • Overpaintability with all conventional paint systems

Benefits of HDK® Pyrogenic Silica:

  • Reduced settling of zinc dust
  • Easier stirring
  • Prevention of gas formation
  • Rheology control
