Nano-coatings for stones (mineral surfaces)

Nano-coatings, based on silicon dioxide
for stones (mineral surfaces)

These products are optimised for absorbent surfaces because of their formulation.
They can therefore be used as an invisible, water- and contamination-resistant, UV-stable coating of porous substrate surfaces, regardless of whether the surface is a natural stone such as sandstone, concrete, terracotta, clay brick or stone panelling.

Floor or wall coatings, building facades, functional terracotta or roof tiles are all in the scope of application for this product. Since nano-coatings only apply an ultra-thin coating on the inside of the pores, the substrates remain breathable after the coating - the perfect structural protection. The majority of the contamination is washed away by the rain.

Examples of use:

  • Every type of porous surface with a mineral-based origin
  • Concrete
  • Lime stone
  • Sandstone
  • Concrete blocks
  • Porous granite / marble
  • Roof tiles / clay
  • Terracotta

Product characteristics:

  • Strong hydrophobic + oleophobics
  • Strong non-stick properties
  • Excellent easy-clean effect regarding deposits of air pollution

Advantages:

  • No influence on the appearance of the substrate (Layer thickness: 100-150 nm)
  • Excellent Hydro and Oleophobic properties
  • Solvent-free and odourless
  • Hardening at room temperature. No additional energy or UV light required.
  • Pressure wash-resistant (50 - 60 bar)
  • Excellent efficiency with low quantity consumption
  • No colour infiltration to coated substrates.
  • High temperature-resistance - UV-stable
  • Absolute frost-resistance

Other positive Effects, such as e.g.

  • No contamination can infiltrate the pore-structure through water.
  • Easy cleaning
  • Enduring impregnation enables very high freeze-thaw resistance and no cracking because of ice.
  • very heavy reduction of moss and fungus growth
  • Longer life-spans for substrates because of lowered cleaning cycles.
  • Enduring protection for the surface structure.
  • Weather damage prevention
    • Advantages easy-clean nano-coatings, based on silicon dioxide coatings in comparison with competitive products

      Permanence and longevity:

      • the UV-stability enables a lifetime performance of the coated surface – assuming it is not damaged by abrasion
        Many competitive products like silicon oils or fluorocarbon technologies are slowly destroyed by sunlight
      • (Abrasion resistance) – negligible on mineral surfaces due to the low abrasion resistance of the substrate

      Chemical stability:

      • The product is resistant to almost all standard household and industrial cleaners (with the exception of concentrated alkaline solution)
        Many competitive products do not have this property and must be reapplied

      Application

      Simple do-it-yourself application makes it suitable for end-customers as well:

      1. Industrial: Application using standard HVLP systems
      2. Manual: Application by wetting the surface (spraying or dipping)
      The nano-coating is completely networked and hardened after 24 hours. The easy-to-clean effect can only be tested after this hardening phase

      Graffiti-resistance

      Special high-quality SiO2-coatings are excellent graffiti protection.
      Nano-anti-graffiti coatings are graffiti-resistant coating formulas for application on porous silica-based substrates, such as sandstone, concrete, Terracotta and clay.

      More information is available upon request. Nano-Care Deutschland AG distances herself from the colloquial term "nano-sealant" for glass, ceramic, textiles, stones and other surfaces. It was built by the market in the last 10 years and it is not correct from the technical point of view. Our nano-coatings are not sealing the surface – they protect it without impeding the breathability of the substrate.
