Sikagard® WallCoat AS-11 Hygienic
Single component, waterborne, low emitting, acrylic resin wall coating
Sikagard® WallCoat AS-11 Hygienic is a wallcoating system, based on waterborne modified acrylic resin containing an in film preservative to protect the coating from attack and degradation by bacteria, funghi, mould, yeast and algae.
- Seamless, easy to clean finish
- Very low emission of VOC
- Good resistance to repeated cleaning regimes using mild detergents and cleaning solutions
- No degradation of the film caused by bacteria, funghi, mould, yeast and algae
- Tough and highly durable
- Good water vapour permeability
- More flexible in comparison to standard acrylic systems, improves the resistance to cracking and flaking
- Solvent free
- Good opacity
- Odourless
- Easy to apply
Usage
- Application on concrete, bricks, cement and gypsum based substrates, metal surfaces, timber, tiles and plastic
- Suitable for production facilities in the pharmaceutical, medical engineering, food and beverage industry, hospitals, prisons, healthcare and leisure facilities
