Product Details

Conbextra EP10(M) is a two part epoxy resin system for grouting gaps ranging from 0.25mm to 9mm. It is an all liquid system consisting of a base and hardener. Advantages   Moisture insensitive   Low creep characteristics   High compressive, tensile and fl exural strengths   Fast, convenient pumping with early strength gain   Withstands a wide range of chemicals Technical support Fosroc offers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, Fosroc offers technical support service to specifi ers, end-users and contractors, as well as on-site technical assistance in locations all over the country. Properties The following results are typical for the hardener grout at 30 deg.C. Test method Typical result Density (Kg/m3 ) 1060 Compressive strength ( N/mm2 ) ASTM D695 60 Tensile strength (N/mm2 ) ASTM C307 - 94 20 Flexural strength (N/mm2 ) BS6319 Part 4 45 Chemical resistance Conbextra EP10(M) is resistant to oil, grease, fats, most chemicals, mild acids and alkalis, fresh and sea water. Pot life Ambient temperature affects the time for which bulk material will remain fl uid. Typical values in minutes are : 200C 300C Conbextra EP10(M) 60 30 Conbextra EP10(M) Exotherm All epoxy systems will develop a temperature rise on mixing. Its extent will be a function of the volume to surface ratio, the ambient temperature as well as the mass and thermal conductivity of the surrounding materials. Contact Fosroc for specifi c data on each product. Application instructions Prepare the surface and seal the cracks with a sealing compound which can also be used for bonding injection nipples. Depending on the crack width and depth the distance between nipples should be 200 to 500 mm. Mixing and placing Pour all the contents of the hardener pack into the base container. Mix using a slow speed power mixer for 60 seconds. Use a suitable pressure pump for injecting the material into cracks. After 24 hours remove the nipples and seal the holes or voids with more sealing the compound and allow to cure. For fi lling cracks of more than 10mm and using as an epoxy mortar Conbextra EP10(M) has to be mixed with clean graded quartz sand from 1:3 to 1:6 parts by weight depending on the consistency required. Mixing can be done with a paddle fi tted to a drilling machine. Typical propertes are as follows : Compressive strength (N/mm2 ) @ 7 days : 50 Tensile strength ( N/mm2 ) : 3 - 4 Flexural strength ( N/mm2 ) : 10 Cleaning All tools and equipment should be cleaned immediately after use with Nitofl or Sol. Spillages should be absorbed with sand or sawdust and disposed in accordance with local regulations.
