SiliXan W

SiliXan W– epoxide containing polymers based on nano-scaled silicon dioxide

 pille-w

The SiliXan W product class is used to formulate aqueous coatings for glass, metals and plastics. An application in water-miscible solvent systems is also possible.

This binder class stands for water-based inorganic-organic polymers that contain nanoscale silicon dioxide (SiO2) and stable aliphatic epoxy groups.
Improved adhesion and abrasion resistance is already achieved on glass with an addition of 5 to 10%.
On metals made of steel, stainless steel, aluminum or zinc, the initial adhesion as well as the adhesion under corrosion stress is significantly improved, i.e. undermining of the coating and blistering is significantly reduced. Intercoat adhesion is increased for improved recoatability.
Furthermore, the products increase the abrasion resistance and compatibility with inorganic pigments and fillers in water-based plastic coatings.

The SiliXan W product line can be used to formulate efficient anti-corrosion coatings and to improve abrasion and chemical resistance in transparent and pigmented coatings based on polyurethane, acrylic, epoxy or melamine resin.

The SiliXan W products have between 30 and 50% solids and are free from aromatic epoxides or bisphenols. They contain water as a solvent and 5 to 10% ethanol as a co-solvent.

Mode of action of SiliXan W

 Reaction SiliXan W SmallThe following possible fields of application result for SiliXan W products:
  • Good adhering thermal curing coatings for aluminium and stainless steel (without primer)
  • Direct adhering coatings for glass
  • Abrasion resistant coatings for plastic
  • Reprintable coatings
  • Co-binder in aqueous acrylate and PU dispersions (1K)
  • Co-binder in water-based, forced-drying 2-component PU systems
    (reaction as capped diol with isocyanate)
  • Sole binder for curing at temperatures between 80 and 180°C
  • Binder or co-binder in aqueous RT-curing 2-component epoxy systems (cross-linking with amines)
  • Reactive partner for cross-linking with melamine, usually at temperatures from 80 to 180 °C
  • Wax-free and lubricant-free tribological coatings (bonded coating)
  • Hydrophilic coatings as well as antifog properties
  • Additive for sol-gel systems
