Protectosil® BHN PLUS

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. By combining a low surface tension with a tailored rate of reaction, Protectosil BHN PLUS is able to move through the moisture boundary layer which lines the pore structure of the substrate. This permits the development of uniform gradient permeation or a consistent level of protection throughout the entire depth of penetration. This allows for a longer life of the treatment especially on wearing surfaces.

Typical Applications

For use on vertical or horizontal concrete and masonry surfaces to repel water and oil based materials from penetrating into the substrate. Reduces staining and discoloration of concrete, brick masonry, limestone, marble, granite, natural stones and other building materials due to oil and water borne contaminants. For use on reinforced concrete to protect against corrosion due to water, deicing salts and salt water. Apply to masonry to prevent the ingress of wind driven rain while maintaining surface appearance and breathability.

Benefits at a glance

Protectosil BHN PLUS is a mixture of an alkyltrialkoxy silane and a proprietary oil repellent additive. Protectosil BHN PLUS penetrates deeper than traditional silane and siloxane products due to its unique chemistry. This deeper penetration gives a long lasting, high performance water and chloride screen. By greatly reducing water entering the substrate and with it being a breathable system, a “drying out” of the substrate occurs.
The oil repellent additive creates an area of extremely low surface tension on the substrate. This effect renders the surface resistant to the ingress of oil based materials. In addition, the repellent effect against food product is much greater than that imparted by traditional water repellent. The primary function of the Protectosil BHN PLUS is to allow easier cleanup and reduce staining of the substrate due to the absorption of various oil and water based contaminants. If spills are not cleaned up in a timely manner staining and absorption into the substrate will still occur. Contact your Protectosil representative for compatible cleaning methods. The main benefits of the product are:
• Excellent resistance to automotive fluids
• Excellent repellency of food products
• Reduces staining
• Excellent resistance to chloride ion ingress
• Breathable system
• Mitigation of AAR & ASR deterioration
• Deep penetration into substrate
• No change in surface appearance
• High resistance to alkali attack
• Long service life
