Exceptional Mechanical StrengthAchieving compressive strength greater than 90 N/mm2 and a tensile strength over 15 N/mm2 at 7 days, Conbextra EP10 / EP10(M) delivers robust support for heavy loads, machinery, and structures requiring a secure and durable base. Its flexural strength of more than 35 N/mm2 further enhances resilience against stress and vibration in industrial settings.
Advanced Chemical and Oil ResistanceFormulated to resist aggressive chemicals, oils, and industrial fluids, this epoxy grout offers long-term durability in environments that would typically degrade ordinary cementitious grouts. Its non-porous nature once cured ensures minimal water absorption and prevents deterioration from harsh agents.
Versatile and Reliable ApplicationSupplied in a ready-to-use mix ratio with components packed for convenience, Conbextra EP10 / EP10(M) maintains consistent quality. It can be applied in thicknesses up to 10 mm and is suitable for grouting machinery base plates, anchor bolts, and columns where strong bonding and chemical stability are crucial.
FAQ's of Fosroc Conbextra EP10 / EP10(M) Epoxy Resin Grout:
Q: How should Fosroc Conbextra EP10 / EP10(M) be mixed and applied?
A: Mix the pre-weighed components exactly as supplied to ensure consistent results. Combine the resin, hardener, and aggregates using a slow-speed drill and paddle until homogeneous, then pour and place immediately within the 45-minute pot life at 30C. Ensure prepared surfaces are clean and dry before application.
Q: What are the main benefits of using Conbextra EP10 / EP10(M) epoxy resin grout?
A: This grout offers high early and ultimate strength, excellent chemical and oil resistance, non-shrink behavior, minimal water absorption, and strong adhesion to concrete, making it suitable for heavy machinery and precision applications.
Q: When is the grout fully cured and ready for heavy loading?
A: Conbextra EP10 / EP10(M) achieves full cure and maximum strength 7 days after application at 30C. While initial set is achieved in approximately 8 hours, heavy loads should only be applied after this full curing period.
Q: Where can this epoxy grout be used most effectively?
A: It is recommended for industrial and construction settings that require reliable bonding and strength, such as machinery base plates, heavy equipment mounting, columns, and anchoring bolts. Its chemical resistance makes it suitable for process plants and factories.
Q: Can Conbextra EP10 / EP10(M) be used in areas exposed to chemicals or oils?
A: Yes, thanks to its advanced formulation, the grout provides excellent resistance to a wide range of chemicals, oils, and solvents, maintaining its structural integrity in aggressive environments.
Q: What is the recommended storage condition and shelf life for this product?
A: Conbextra EP10 / EP10(M) should be stored in a cool, dry place away from direct sunlight. When kept in its unopened, original packaging, the product remains usable for up to 12 months.
