Mapei Kerapoxy IEG High Chemical Resistance Epoxy Grout

Description Mapei Kerapoxy IEG is a two-component, extremely high chemical resistance epoxy grout for tile joints at least 3mm wide. It is classified as an RG-class reactive (R) grout. Supplied in 10kg tubs, it is available in 113 Cement Grey or 130 Jasmine. Mapei Kerapoxy IEG is for creating acid-resistant grouting with extremely high chemical resistance, for ceramic and stone material floors where higher resistance to chemical products compared with conventional epoxy grouting compounds is required, and in particular to oleic acids and aromatic hydrocarbons. Mapei Kerapoxy IEG allows you to create floors, worktops, etc. in compliance with the HACCP system and the requirements of EC Regulation No. 852/2004 on the hygiene of foodstuffs. Some application examples: ▪ Grouting ceramic floor coverings in ham curers, especially in the areas where trimming, boning and curing are carried out, where the grout comes into contact with animal fats for long periods and is subject to frequent washing with high-pressure jets of hot water. ▪ Grouting ceramic floors in sausage factories, especially where cooking takes place (mortadella, etc.) where the grout is subject to the combined action of oleic acid and high temperatures. ▪ Grouting ceramic floors in oil mills. ▪ Grouting ceramic floors in pickling factories. Technical Characteristics: Mapei Kerapoxy IEG is a two-component, epoxy resin-based product with very low emission of volatile organic compounds, with silica sand and special admixtures. It forms highly compact tile joints with excellent resistance to chemical products and which are very easy to clean, according to a formula developed in MAPEI research laboratories. It is a product with very low emission of volatile organic compounds, classified as Emicode EC1 Plus by GEV. When applied correctly, it forms tile joints with the following characteristics: ▪ extremely high mechanical strength and resistance to chemicals, higher than conventional epoxy grouts ▪ smooth, compact final surface which is non-absorbent and easy to clean, to guarantee a high level of hygiene; ▪ easy to work with and finish off; ▪ high degree of hardness, excellent resistance to heavy traffic; ▪ no shrinkage and, therefore, no cracking. Recommendations: ▪ Use a flexible sealant from the MAPEI range for flexible expansion joints or for joints subject to movement. ▪ Mapei Kerapoxy IEG does not guarantee perfect bonding if the edges of the tiles are wet or contaminated with cement, dust, oil, grease, etc. during grouting. ▪ Always carry out preliminary tests before grouting stone or ground porcelain with a porous or rough surface. ▪ Do not add water or solvents to Mapei Kerapoxy IEG to increase workability. ▪ Use the product at temperatures of between 12°C and 30°C. However, at temperatures below 15°C application may be more difficult. ▪ The packages are pre-dosed and, therefore, it is not possible to make mixing errors. Do not rough guess the quantities when mixing the two components: hardening will be compromised if the catalysing ratio is wrong. ▪ The modulus of elasticity of Mapei Kerapoxy IEG is higher compared with standard Mapei Kerapoxy: therefore, more expansion joints must be included. Application: Preparation of the joints: The joints must be clean, free of dust and empty down to at least 2/3 of the thickness of the tiles. Any adhesive or mortar which has seeped into the joints while laying the tiles must be removed while still fresh. Before grouting, make sure the installation mortar or adhesive have set and most of the humidity has been lost. Mapei Kerapoxy IEG is not harmed by damp from the substrate, but the joints must not be wet when grouting. Preparation of the mix: Pour the catalyst (component B) into the container with component A and mix well until a smooth paste is obtained. We recommend using a low-speed electric mixer to guarantee perfect bonding, and to avoid overheating of the mix which would reduce working times. Use the mix within 45 minutes of its preparation. Application: Spread Mapei Kerapoxy IEG with a special MAPEI trowel, making sure that the joints are filled right down to the bottom. With the edge of the same trowel, remove excess material. The surrounding temperature and the temperature of the tiles have a considerable influence on setting times, workability and cleaning of Mapei Kerapoxy IEG. Finish: After grouting with Mapei Kerapoxy IEG, floors and finishes must be carried out while still “fresh”, by forming an emulsion with water. Solvents must not be used, a further advantage for the environment and user. Wet and emulsify the grouted surface, using a Scotch-Brite pad if necessary, taking care not to remove material from the joints. In the case of very large floor surfaces, finishing may be carried out by wetting the surface and using a single-head rotary machine with special abrasive felt disks such as Scotch-Brite . The residual liquid may be removed with a hard, cellulose sponge (for example a MAPEI sponge). Replace the sponge when it becomes too impregnated with resin. Use the same sponge to even out the grouted joints. After the finishing operation, it is very important that no traces of Mapei Kerapoxy IEG remain on the surface. Once hardened, it is very difficult to remove. Therefore, rinse the sponge often with clean water during cleaning. Residual liquid may be drawn off using a rubber squeegee. Floors are set to light foot traffic after 24 hours at 23°C. Consumption: The consumption of Mapei Kerapoxy IEG varies according to the size of the joints and the shape of the tiles, and must be calculated by considering a density of 1430 kg/m³. The table below shows approximate consumption levels in kg/m² of some types of floor, according to the size and thickness of the tiles. Technical Data: Mixing ratio: component A : component B = 80 : 20 Consistency of the mix: very thick Density of mix (kg/m³): 1,430 Pot life of mix: 45 minutes Application temperature range: from 12°C to 30°C Set to light foot traffic: 24 hours Ready for use: 4 days FINAL PERFORMANCE Flexural strength (EN 12808-3) (N/mm²): 35 Compressive strength (EN 12808-3) (N/mm²): 80 Resistance to abrasion (EN 12808-2): 147 (loss in mm³) Water absorption (EN 12808-5) (g): 0.05 Resistance to humidity: excellent Resistance to ageing: excellent Resistance to solvents and oils: excellent (refer to table) Resistance to acids and alkalis: excellent (refer to table) In service temperature range: from -20°C to 100°C Product Datasheet Click here to view this product on the Manufacturers website.
