This saves time and labour in the mixing process and provides a higher quality control in the mixing and placing of the grout. Gap Thickness Conbextra EP120 is designed to be grouted into gaps from 10mm up to 120mm. Grouting of gap widths below 50mm will take longer to cure due to the low exotherm nature of the grout. If a fast cure of the grout is critical at smaller gap widths please refer to the Conbextra EP40 and EP65 technical data sheets. Grout pours greater than 120mm thick are also possible but care should be taken that the total volume of the single pour should be no greater than 1m³. Technical Support Parchem offers a comprehensive range of high quality, high performance construction products. In addition, Parchem offers technical support and on-site service to specifiers, end-users and contractors. Chemical Resistance Conbextra EP120 is resistant to oil, grease, fats, most chemicals, mild acids and alkalis, fresh and sea water. Consult Parchem Technical Services when exposure to solvents or concentrated chemicals is anticipated. Dimensional Stability For the grout to effectively transfer load from the base plate to the supporting structure it is essential that the grout maintains intimate contact with the base plate. The area of contact between the grout and the base plate is measured as the ‘effective bearing area’ (EBA). In order to maintain an even load distribution throughout the grout it is necessary to attain as high as possible EBA. A dominant factor which influences the EBA achieved with epoxy based grouts is the degree of air entrapment within the product. Air can be introduced into the grout during mixing, or in the case of products which contain a separate dry filler component air can be released into the mixed product as the filler ‘wets out’ over time. Air that is released into the grout as the filler wets out prior to the grout setting can usually be seen as small bubbles in the un-restrained sections of grout. Any entrained air which rises to the grouts surface under the base plate however cannot escape, resulting in a loss of EBA. Conbextra EP120 has been designed and manufactured with the filler pre-dispersed and wetted out (under vacuum) in the resin components. Resulting in a grout which will not continue to evolve air during the filler wetting out process giving a product with the best possible EBA. 143 Fosroc® Conbextra EP120 A high performance two part epoxy grout for dynamic/repetitive load applications suitable for large volume pours Uses Conbextra EP120 is for use in situations where heavy dynamic or mobile loads are encountered. The gap between a base plate and substrate needs to be filled and the structural load be uniformly distributed. Applications „ Reciprocating machinery „ Testing equipment „ Heavy crane and transporter rails „ High speed turbines „ Centrifuges and drop forges. Also for use in conditions where chemical spillage may be encountered. Typical situations could be met in steelworks, refineries, electroplating works and chemical plants. Conbextra EP120 is especially suitable where long working time and/or low exotherm properties are required e.g. for large pours or high ambient temperatures. It can also be used for grouting wide gap ranges making it a versatile product for a number of applications. Advantages „ High compressive, tensile and flexural strengths „ Resistant to repetitive dynamic loads „ Fast, convenient installation „ Withstands a wide range of chemicals „ Virtually no shrinkage and hence ensures complete surface contact and bond „ Low creep characteristics under sustained loading „ Excellent flow properties „ Two part material giving a better quality control during mixing „ Can be used installed at high temperatures „ Wide range of gap thicknesses are possible June 2014 Page 1 June 2014
