Protectosil® 100 N

Recommendations for use- As a water repellent for mineral building materials especially substrates with low porosity e.g.

• Concrete (road bridges, port facilities and all marine concretes, concrete facings, exposed aggregate concrete)
• Clinker brick
• Ceramic tiles
• As a water repellent under topcoats

Applications

• Solvent-free
• Very low volatility, no loss of active substance by evaporation
• Water vapor permeable, colorless impregnating agent
• No formation of a sticky silicone film
• Effective on micro cracks up to 0.3 mm
• Greatly reduces the uptake of water and damaging water-borne salts (e.g. chlorides)
• High depth of penetration
• Resistant to alkali
• Protects against alkali-aggregate reaction in concrete
• Meets TL/TP-OS of the ZTV SIB 90 standards set by the German Federal Transportation Ministry
• Frost resistant.

• The substrates to be treated should be air-dry and clean in order to ensure deep penetration of the active ingredient. During application the outside temperature and the temperature of the substrate should be within the range of 0 °C to 40 °C. The material should not be applied if there is strong wind or if it is raining. The material must not come into contact with water either before or during use.
• Protectosil® 100 N must be applied by flowcoating to the saturation point. This is achieved by allowing it to flow without pressure against the surface to be treated. All liquid delivery devices are suitable (airless sprayguns, for example). The material must not be atomized or applied with a brush.
• A liquid film of Protectosil® 100 N must remain in contact with the surface to be treated for several seconds. Horizontal areas must have a light-reflecting "wet" appearance for 3 to 5 seconds. Vertical surfaces should exhibit a 30 - 50 cm long, light-reflecting curtain marking the advance of the liquid.
• All equipment and containers must be clean and dry. After use, they can be cleaned with any organic solvent (methylated spirit, petrol or thinners).
• Non-absorbent substrates such as, for example, glass, wood, plastic and metal cannot be treated with Protectosil® 100 N. Glass, wood, and metal are not attacked by Protectosil® 100 N. Neither are most plastics used in construction. Therefore covering is normally not necessary. To make it sure we recommend to carry out a test. In the worst case, product not absorbed by the substrate may react with atmospheric moisture to form a greasy, glossy silicone resin film, which can easily be removed if cleaned immediately using conventional cleaning agents or alcohol.
• Protectosil® 100 N reacts with the interfaces in pores and capillaries of the mineral surface and forms invisible, waterrepellent interfacial compounds. However, since it is frequently unknown whether the material has been previously treated, a test should always be performed on a small area to make sure that no undesired secondary phenomena occur. Plants in the vicinity of the substrate to be treated are to be protected against contact with the waterproofing agent.

• Protectosil® 100 N is available in 25 kg and 180 kg drums.

• The storage temperatures are between -10 °C and 40 °C. Protectosil* 100 N has a shelf life of at least 12 months if stored in originally sealed containers.
