Emer-Stop Creme is particularly useful for impregnating the exposed surfaces of reinforced concrete used in bridges, wharves, roads, on all atmospherically exposed concrete buildings and structures. Advantages „ Outstanding penetration „ Chemically bonds to concrete substrates „ Optimum resistance to alkalis „ Drastic reduction in capillary water absorption „ Low volatility, no application wastage „ Allows water vapour transmission „ Thixotropic, can be applied in windy / elevated temperature conditions, even to vertical and soffit applications „ Easy to supervise; clearly visible applied material, easily measured material thickness „ Water based, solvent free, environmentally friendly Description Emer-Stop Creme is a thixotropic, water dispersed emulsion of iso-octyltriethoxysilane for use as a penetrating water repellent treatment for concrete. Being a reactive silicone based product, it chemically bonds with concrete and masonry substrates and becomes invisible once dry. Its penetration and subsequent chemical reaction with the concrete allow it to provide long term protection for concrete by significantly reducing the ingress of liquid water and any dissolved salts that the water may carry. The high concentration of active ingredient (> 80%) is unique among other emulsion type silanes. One of the most aggressive agents responsible for the breakdown of steel reinforced concrete in marine or coastal environments is chloride ions present in sea water and wind borne salt spray. Water soluble chlorides are able to penetrate the capillaries of unprotected concrete. When these chloride ions reach the reinforcing steel, corrosion will commence. Over time, the chloride-ion induced corrosion may affect the reinforcement steel’s structural integrity. Emer-Stop Creme works by penetrating the capillaries of the concrete, chemically reacting with the concrete to form a continuous hydrophobic coating over the surface. This hydrophobic (water repelling) coating prevents the ingress of liquid water carrying chloride ions. The high concentration of active silane in Emer-Stop Creme combined with the low evaporation rate of the product, allows the maximum possible depth of penetration and protection to be achieved. Unlike other types of silane treatments, Emer- Stop Crème is highly visible at the time of application and can be easily applied to vertical or overhead soffit applications. The thixotropic nature of Emer-Stop Creme minimises waste and ensures that all of the silane applied to the substrate is available for penetration. This product application control is particularly important in ensuring the product is not lost into the environment, and can be used over waterways. The highly visible nature of the product during application, allows an easy visual inspection to ensure that the entire surface has been covered. A single application of Emer-Stop Crème is usually sufficient. Application rates for Emer-Stop Crème may vary from 0.25 - 0.44 litres/m² depending on the porosity of the substrate. An application rate of 0.25 litres/m² will be sufficient for high quality off-form concrete with a high density and low absorption. An application rate of up to 0.44 litres/m² would be required for low quality porous concrete. On porous substrates a second application may be required. September 2011
