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.

• 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.

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.

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. 

Reference projects include Times Square in New York City, Disney Resorts, Universal Studios, and several sports stadiums in the US.

• generates water vapour-permeable, colourless impregnation
• not film-forming
• reduces significantly the uptake of water, chlorides, automotive fluids and food products.
• protects hairline cracks of up to 0.3 mm
• is supplied ready to use
• food contact safe once cured
• low VOC

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.

Reference projects include Credit Suisse Zurich, and the Zollverein School of Management and Design, Germany.

• treated surfaces remain cleaner longer making coffee, soft drinks, pollution, dirt, easy to remove.
• weakens the adhesion of chewing gum or posters to facades
• slows down the growth of microorganisms such as mold and algae
• is supplied ready to use or as a concentrate to be diluted with water
• food contact safe once cured
• no formation of sticky silicone film
• can be applied over hydrophobated surfaces such as concrete with integral waterproofing.
