TM MASTERFLOW 400 Rapid curing flowable epoxy grout with high early strength Description MASTERFLOW 400 is a solvent free, three-component, filler-extended, high flow, epoxy resin grout. It is formulated to grout static and dynamic equipments that require a very high effective bearing area. MASTERFLOW 400 can be applied to properly prepare and formed voids from 10 mm to 80 mm deep in a single stage pour. Uses Crane and transporter rails Base of pumps, compressors; milling and paper making machines New and old machine base plates Structural filling of holes and cavities in concrete Industrial equipment and machinery subject to static or dynamic forces Equipment where chemical and acid spillage occurs Advantages No priming required High flow characteristics Long pot-life High tensile, flexural and compressive strength Excellent adhesion to steel and concrete Rapid installation and strength gain High resistance to dynamic loads and chemical attack Typical properties Mixing Ratio, by weight Mix Density Volume solids Pot life Compressive strength, at 25°C ( ASTM C579) Flexural Strength, (BS 6319 part 3) Tensile Strength, (BS 6319 part 7) : : : : : 3 (B) :1(H) :16 (F) 2000 Kg/m3 100 % 60 Minutes at 25°C : : : : : : 50 MPa at 6 Hours 80 MPa at 1 Day 90 MPa at 3 Days 100 MPa at 7 Days 27.5 MPa at 7 Days 13 MPa at 7 Days Directions for use Surface preparation: As with all epoxy resin applications the quality of surface preparation has a direct effect on the performance and durability of the system. Concrete must be sound and fully cured (28 days). Substrate and base plate contact area must be clean and dry. Remove rust, dirt, oils, grease and other contaminants that may inhibit bond. Abrade or roughen the concrete to optimize the bond. All metal components to be in contact with MASTERFLOW 400 must be mechanically abraded to a bright white metal finish for maximum adhesion. If an anchor bolt sleeve is to be filled, be sure all water is removed. Use a siphon, vacuum pump, or rubber hose and bulb. Remove the residual moisture by either forced air or evaporation. Seal the anchor bolt hole with felt, foam rubber or other means. Cover all shims and levelling screws with putty or clay to keep the grout from adhering. Use model clay, glazing putty, etc with putty consistency that will stick but not harden. Shims or jack pockets may be formed with wood, and forms filled with damp sand. Remove shims or jack screws after the grout cures. 30 Minutes at 40°C To facilitate cleanup, wax or cover all surfaces where the grout may splash or spill. Specification Clause The rapid-curing, high flow, filler-extended epoxy resin grout shall be MASTERFLOW 400. The grout shall exhibit high early strengths by exceeding compressive strength of 75 MPa at 1 day and 100 MPa at 7 days; shall exceed flexure strength of 25 MPa at 7 days. The formulation shall be of 100% solids and free of solvents. Chemical resistance MASTERFLOW 400 resists the following most common corrosive chemicals Dilute and concentrated alkalis Most dilute acids Oil and petrol Ammonia Formaldehyde Saline solutions Mineral oil, vegetable and animal fats Shade the foundation from direct sunlight for at least 24 hours before and 48 hours after grouting. Forming Protect the foundation and equipment from rain or moisture. Water will tend to prevent grout bond and inhibit cure. Seal off areas that will not be grouted. Place forms no greater then 50 mm away from the edge of the individual base rail or sole plate on the Page 1 of 2 sides where grout is not being poured. Excessive edges create thermal stress and result in excessive cracking. On the pouring side forms are typically 50 to 150 mm away from the supporting area. However, this may vary depending on the application. Moderate to large size equipment and difficult or narrow placement applications should utilize an extended head form (head box) to create additional head pressure and to enhance placement. Consult BASF representative for specific recommendations. Before erecting the forms, cover them with extras heavy coat of paste wax or shall be wrapped in polythene to ensure a clean release. The top of the form should extend at least 15mm above the bottom of the rail or plate. Forms must be liquid tight. They may be sealed with putty, foam or caulk. Seal wood forms to vertical concrete surface by applying putty, foam or caulk below top of concrete and then press form in to place. Mixing To ensure proper placement consistency, condition the kits to 21oC for 24 hours before using. Resin viscosity is dependent on temperature. Resin viscosity is more viscous and difficult to mix at lower temperatures. Do not split packs or alter the ratio of resin components in any way. Do not thin any component of this product. Mix with a slow speed drill and paddle. Add the contents of the Hardener container to the Base component or in a suitable mixing vessel, ensuring complete transfer of both resin components. Scrap the inside walls of the can to achieve the proper mixing ratio. Mix for one minute before slowly adding the aggregate and continue mixing until a flowing, pourable lump free consistency is achieved. Mixing for too long or using high speed drill will entrap air; avoid air entrapment. Placing: Place immediately after mixing, into the prepared area in such a manner that it has the shortest distance to flow. For long pours a suitable head of pressure may be required. Ensure the area to be grouted is not completely sealed, and any displaced air can be expelled. Pour continuously from one side only. Grout should come up at least 10 to 15mm onto the equipment; mask the area above it with masking tape. Allow the grout to set prior to removal of formwork (normally after 6 hours). Where placement exceeds depths of 80mm, application should be carried out in layers. Allow for 6 to 8 hours before placement of second layer. Equipment care Clean all equipment promptly with CLEANING SOLVENT NO. 2. Any excess cured material will have to be mechanically removed. Packaging MASTERFLOW 400 is supplied in 20kg pack which shall yield 10 Litres of volume per pack. Storage and Shelf life Store under cover, out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in an air-conditioned environment. Shelf life is 12 months when stored as above. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice please consult BASF's Technical Services Department. Safety precautions As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until product fully cured or dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek immediate medical attention. Keep away from children and animals. Reseal containers after use. Do not reuse containers for storage of consumable item. For further information refer to the material safety data sheet. MSDS available on demand or on BASF construction chemicals web site.
