Product description
Crack-bridging mineral, white, elastic coating. It has high resistance to mineral oils and aliphatic hydrocarbons. Resistant to pressurized water and mineral oils.
Properties
- two-component, solvent-free, liquid consistency
- flexible and crack bridging waterproofing material
- very high adhesion to wet and dry surfaces
- liquid consistency, thanks to which it is very easy to apply, even on complex structural elements
- coating resistant to UV radiation, which allows it to be used outdoors and indoors
- the white color reflects solar radiation, preventing the coating from heating up
- the coating has a short setting time
- high flexibility,
- resistance to aging, poor pedestrian traffic, hydrolysis and de-icing salts
- frost-resistant product
- the material is resistant to oil in synthetic and aliphatic hydrocarbons at high boiling point (up to 2 bar)
- the product is not resistant to substances containing aromatic hydrocarbons such as benzene, xylene, toluene
- does not contain volatile organic substances (VOC = 0),
- does not contain polyurethane, isocyanate or bitumen
Application
- underfloor waterproofing in buildings
- waterproofing foundation in (on the side of pressing water)
- waterproofing the tank in the flat roof above unheated rooms
- insulation under ceramic cladding, on terraces, balconies, it can also be used as a protective coating against mineral oils and aliphatic hydrocarbons
