Emer-Stop S100N is especially suitable for protecting concrete structures in marine and coastal environments. Advantages „ Reduces water and chloride ingress „ Deep penetration into porous substrates „ Allows water vapour to escape from the structure „ Environmentally friendly - solvent free „ Exceptional alkali resistance „ Reduces the effects of Alkali-Silica reactive aggregates „ Increases freeze thaw resistance „ Minimises efflorescence „ Chemically resistant to ice melting compounds, fuels, oils and atmospheric contaminants Description Emer-Stop S100N is a low viscosity colourless neutral liquid. It has a >98% active content of monomeric isobutyltriethoxy silane which, due to it’s low rate of hydrolysis, penetrates deeply into porous substrates, reacting to produce a bonded hydrophobic lining to the pores. In particular, being solvent free, the product is distributed with uniform high concentration practically throughout the entire penetrated area. This treatment markedly reduces absorption of water and water-borne salts, but still permits passage of water vapour gas out of the structure. The treatment is not affected by UV light and does not produce any discolouration of the substrate. Technical Support Parchem offers a comprehensive range of high performance, high quality repair, maintenance and construction products. In addition, Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical support. Design Criteria Emer-Stop S100N should be applied in a minimum of two flood coats. To achieve the correct penetration and protection Emer-Stop S100N must be applied on the substrate at the coverage rates recommended. Properties The values obtained are for the Emer-Stop S100N system applied at the minimum recommended application rate. Specific gravity: 0.88 @ 20°C Active component: Isobutyltriethoxy silane Purity: > 98% Refractive index: 1.400 Viscosity: < 10.00 CST @ 20°C Specification Clauses The penetrating water repellent treatment shall be Emer- Stop S100N which has a > 98% active content of monomeric isobutyltriethoxy silane, designed to produce a reduction in water uptake of > 80% and a chloride resistance of > 95%. In line with international standards the application of the IBTEO shall be tested using cores taken from site. Parchem recommend testing to establish penetration depths. Application Instructions Pre-application testing Prior to commencement of spraying, test areas should be marked out. Emer-Stop S100N should be applied to these areas by the contractor. On completion of spraying these areas, core samples should be taken and the following test should be carried out. Determination of depth of penetration of applied treatment by water uptake. Preparation Surfaces should be dry and free from contamination such as oil, grease, loose particles, decayed matter, moss, algal growth, laitance and all traces of mould oils and curing compounds. Protect plants, glass, asphalt, bitumen, plastics and all painted surfaces prior to application. Application In order to obtain the penetrating properties of Emer-Stop S100N, it is important that the correct rates of application and overcoating times are observed. September 2011
