MegaTamir Epo Epoxy

MegaTamir Epo Epoxy Based Adhesive And Repair Mortar PRODUCT DESCRIPTION A double component, solvent free filling, repair, grading and adhesive mortar with epoxy bonding and reduced slippage, which is resistant to water and chemical environments. AREAS OF USE MegaTamir Epo is used for the filling and grading of holes and gaps on concrete and metal surfaces, as anchor mortar for inserting iron ores, for the repair of cracks and fractures, for the protection of bonding of concrete to metal and metal to metal by filling the remaining gaps against corrosion, and as adhesive for the adhesion of numerous construction materials. It is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces. PRODUCT ADVANTAGES • Highly resistant to chemical effects. • Gains high strength shortly after the application. • Highly resistant to dynamic loads. • Highly resistant to wear and tear and poses high mechanical resistance. • Ensure excellent adherence for numerous dry and clean surface types. • Easy to mix and apply thanks to the special fillings in its content. • Solvent-free and environmentally friendly. PERFORMANCE Compression strength ≥ 75 N/mm 2 TS EN 1504 - 4 : 2008 Bending strength ≥ 32 N/mm 2 TS EN 1504 - 4 : 2008 Tensile strength ≥ 17 N/mm 2 TS EN 1504 - 4 : 2008 Concrete bonding strength ≥ 4 N/mm 2 TS EN 1504 - 4 : 2008 Bonding strength to sanded steel ≥ 17 N/mm 2 TS EN 1504 - 4 : 2008 The foregoing values represent the results of the laboratory tests conducted at 23 ± 2°C temperature and 50% ± 5 relative humidity conditions. The values provided as per the table may vary depending on the surface and ambient conditions. REFERENCE STANDARDS Certifications/Standards TS EN 1504 - 4 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.613/8E QUALITY CERTIFICATES Conformant to TS EN 1504 - 4. APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Cement based plaster - Fresh - old concrete - Iron - steel Indoors and Outdoors Floors; - Cement based trowel coating - Fresh - old concrete - Iron - steel Surface Preparation Iron - Steel Surfaces • Iron and steel surfaces should strictly be sanded prior to application. • MegaTamir Epo should be applied to the surface within 4 hours following the sanding. In the cases, where the product is not applied within 4 hours following the sanding; the surface should be sanded once again immediately prior to the application. Fresh Concrete • The application surfaces should have completed the 28 day curing period. • Such materials as mortar residues on the cured surface should be removed by mild sanding or brushing, whereupon the surface should be thoroughly cleaned from dust. Old Concrete • The application surfaces should be dry, clean, sound and dust free, and should have been cleansed of oil, dirt or any materials that may prevent adhesion, and any such materials as mortar and cement residues should be scraped from the application surface. • Due care must be taken to ensure that the surface is completely dry prior to the application. The humidity ratio of the concrete should be 5 % at maximum. Application Methods • MegaTamir Epo should be applied in equal thickness on all surfaces to be repaired. • The surface should be finished with a smoothing trowel following the application. • The mixture to be prepared should be consumed within 60 minutes. Any mixture, the pot life of which has expired or which has hardened, should be disposed. Application Recommendations • MegaTamir Epo may pose increased consistency when stored in cold weather conditions. In such cases, the normal consistency of the product should be restored by being moved to a warm environment or bathed in hot water (having the materials kept in a container filled with hot water prior to mixing). • The product should, once mixed, be used before the expiration of its pot life. Any product, the pot life of which has expired, should not be used during the application. Epoxy based products have limited pot lives; therefore, due consideration should be given to the fact that the pot life and dry times would shorten at high temperatures and lengthen at low temperatures. • Any such foreign substance as lime, cement or plaster should not be added to the product, which prepared with compounds. • The product should not be applied on unsound surfaces. The soundness and the load bearing capacity of old surfaces should be checked prior to adhesion. • The surface should be preserved from air currents and water contact during and after the application. • The product should not be applied to such surfaces, which are exposed to risk of freezing within the next 24 hours, which are frozen or the frost of which is thawing. • Due care should be taken to ensure that the material is not exposed to direct sunlight in hot weather conditions. • The product should not be applied on extremely windy weather conditions or on hot surfaces, which are exposed to direct sunlight; and in the cases, where application is imperative under such conditions, the environment and the surface should be prepared for application in advance. • The product should not be applied in rainy weather conditions, and the application surface should be preserved from rain for a period of 24 hours. • Refer to our technical support hotline for recommendation on different surface applications. (PHONE: 444 4 595) Surface and Ambient Temperature The surface and ambient temperature should be between +5°C and +35°C whilst at application. Application Limits Useful time for prepared product - Pot life Surface dryness Through dry time Through curing The foregoing values represent the results of the laboratory tests conducted at 23 ± 2°C temperature and 50% ± 5 relative humidity conditions. The values provided as per the table may vary depending on the surface and ambient conditions. APPLICATION INSTRUCTIONS Mixing Ratio Component A (4.5 kg) and component B (1.5 kg) should be thoroughly mixed. Mixing Equipment • Low speed electrical mixer (400 cycles/min.) • Special tip stirring equipment Mixing Period The product should be stirred with a low-speed mixer until any dry dust and globs are eliminated. The mortar should, then, be stirred once again for 1 to 2 minutes after being had settled for 3 to 4 minutes following preparation. Application Equipment • Steel trowel • Scraper • Mortar / Mastic gun Equipment Cleaning The equipment used should be cleaned with such solvents as thinner, acetone or toluene immediately after the application. The non-cured epoxy on the application surface should be cleaned with a moist sponge or a moist sponge mildly saturated with detergent. The dried epoxy can be cleaned mechanically. In order for easy mechanical cleaning; the contaminated tools may be kept within such solvents as thinner, acetone or toluene for 1 to 2 hours, which would soften the epoxy. TECHNICAL PROPERTIES Chemical Structure: Solvent free repair mortar with epoxy bonding Density: 1.75 ± 0.1 gr/cm 3 Solid Matter Content: %100 Color: Gray Maximum 1 hour Minimum 4 hours Minimum 18 hours 7 days CONSUMPTION Recommended consumption amount for application in roughly 1 mm thickness on 1 m 2 surface is 1.5 - 2.0 kg. The said value may vary, depending on the surface and ambient conditions. 97
