Protection and Corrosion Control

Protectosil BHN

Penetrating Water Repellent Silane, Solvent-Free

**STOCKED IN SINGAPORE**

Undiluted, solvent-free silane water repellent impregnation for mineral substrates. Protects against the ingress of water and water soluble pollutants.  Protectosil BHN reacts with the boundary surfaces in pores and capillaries of the mineral surface and forms and invisible, water repellent boundary.

Protectosil BHN boasts a 30-year track record and is estimated to extend service life of concrete structures to 100+ years.  Reference projects include the Sydney Opera House and the Hangzhou Bay bridge.

REQUEST INFORMATION

  • specially suited for the water repellent impregnation of mineral construction materials in outdoor areas
  • highly reactive and resistant against alkaline environment
  • reaches very high penetration depth
  • not film-forming
  • reduces significantly the uptake of water and soluble salts (i.e. chlorides)
  • protects hairline cracks of up to 0.3 mm
  • is supplied ready to use
  • food contact safe once cured
  • is also recommended as waterproofing under coatings or other surface protection treatments
  • awarded "Green Label" in Sweden
  • frost resistant
  • conforms to TL/TP OS-A of ZTV SIB 90 standards set by the German Federal Transportation Ministry and to the EN 1504-2.
  • can be used according to principles 1, 2, 5, and 6 of EN 1504-9

Concrete treated with BHN shows a deep layer of protection against water ingress. The dark center shows where a water-based dye, applied after cutting in half, was able to penetrated the untreated areas.

Areas of Application

For waterproofing of mineral substrates: 

  • concrete (fresh or carbonated, road bridges, port installations and all marine concrete structures, concrete facades, exposed aggregate concrete)
  • natural stone (marble, granite, limestone)
  • Cement render
  • clinker masonry
  • ceramic tiles
  • clay tiles
  • Protectosil BHN is also recommended as waterproofing under coatings or other surface protection treatments. (BHN should cure for about two weeks before applying Protectosil Antigraffiti or Protectosil SC)

Protectosil CIT

Corrosion Inhibitor for Reinforced Concrete

In the corrosion process, ferrous oxide (rust) takes up more volume than the original steel and causes stress on the concrete. This stress manifests itself as cracks, spalls and delaminations in the concrete structure. But the main consequence of concrete corrosion is the loss of steel cross section and the resulting loss of structural capacity. The three main factors affecting the corrosion rate are the concentrations of chloride ions, moisture and oxygen. Other factors, such as temperature, also contribute to the speed of the corrosion process. Warm, humid environments, such as coastal areas, accelerate the corrosion process and cause very rapid deterioration.

REQUEST INFORMATION

Protectosil CIT works on the molecular level to effectively inhibit the electrochemical interaction of the corrosion process. This advanced inhibiting action makes Protectosil CIT the best choice for difficult applications.

Applied to concrete structures repaired with polymer concrete, Protectosil CIT can equalize the differences in electrochemical potential between the polymer concrete and the existing concrete.

The product:

  • Inhibits corrosion of carbon and galvanized steel rebar
  • Is effective in both marine and high-humidity environments
  • Is easy to apply
  • Is effective in heavily chloride-contaminated concrete
  • Is effective in carbonated concrete
  • Complies with VOC regulations
  • Is vapor permeable
  • Dries quickly
  • Prevents ingress of additional chlorides

Protectosil BHN Plus

Penetrating Water & Oil Repellent Silane

A clear penetrating breathable VOC-compliant surface treatment for use on concrete, brick masonry, concrete masonry units and natural stone.  The unique silane treatment penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule.

In addition, an oil repellent additive resists the ingress of motor oil, transmission fluid, diesel fuel and other automotive fluids.  This additive also repels food products such as mustard, ketchup, food grease, milk, wine, beer and soft drinks. Creates a deep hydrophobic layer which prevents the ingress of water and water borne contaminants from entering the substrate and causing premature deterioration.

Protectosil SC (Stay Clean)

Invisible Facade Protection Silane, Water-Borne

**STOCKED IN SINGAPORE**

Protectosil SC is a water-based silane treatment for the protection of mineral facades against water and oil ingress.  An excellent lotus effect gives the surface self-cleaning properties.  

Protectosil SC reacts with the interfaces in pores and capillaries of the mineral surface and forms invisible, water-repellent interfacial compounds.
