| Sikagard-403 W is a single component, waterborne modified acrylic resin based intermediate and surface coating, containing an antimicrobial additive. - Seamless, easy to clean finish
- Good resistance to repeated cleaning regimes using mild detergents and cleaning solutions
- Tough and highly durable
- Good water vapour permeability
- More flexible in comparison to standard acrylic paints, improves resistance to cracking and flaking
- Ultra-low emissions
- Good opacity
- Odourless
- Easy to apply
|
Usage - Application on concrete, bricks, cement and gypsum based substrates, metal surfaces, timber, tiles and plastic
- Embedment, intermediate and top coat for internal walls and ceilings
- Suitable for production facilities in the pharmaceutical, medical engineering, food and beverage industry, as well as, hospitals, prisons, healthcare and leisure facilities
