    Prerit Surface

    Prerit Surface belongs to the new generation of water-soluble fluorinated silica compounds, characterised by zero emissions of VOCs and the absence of flammability and toxicity. The active substance penetrates the porosity, adhering to the support and counteracting the penetration and advancement of liquids without blocking the breathability of the support.
    The special chemical structure of Prerit Surface ensures its high stability to alkali and thus its durability over time.
    The product differs from other treatments on the market due to having the following characteristics:
    - non-flammable
    - non-film
    - zero VOC
    - stable in water
    - free from emulsifiers
    - environmentally-friendly
    - durability over time
    - total transparency
    - no variations to the surface colour
    - excellent water vapour breathability
    - elevated pearl effect
    - resistance to acids and alkalis
    - resistance to UV rays
    - an absence of reactive by-products that are harmful to people and the environment
