Conbextra EP10 - Low Viscosity Epoxy Grout

Product Overview

Conbextra EP10 is a two-component low viscosity epoxy grout system specifically designed for grouting gaps up to 10mm and crack injection applications. It is engineered for situations involving dynamic or repetitive loads, making it suitable for high-performance engineering and industrial applications.

Key Features and Advantages

Conbextra EP10 offers several distinctive advantages:

• High Compressive, Tensile and Flexural Strengths - Delivers superior mechanical properties for demanding applications
• Resistant to Repetitive Dynamic Loads - Ideal for machinery and equipment subjected to continuous movement
• Fast, Convenient Installation with Early Strength Gain - Enables rapid deployment and operational readiness
• Chemical Resistance - Withstands a wide range of chemicals including oil, grease, fats, mild acids, alkalis, and fresh/sea water
• Non-Shrink Properties - Ensures complete surface contact and bond integrity
• Low Creep Characteristics - Maintains dimensional stability under sustained loading
• Low Viscosity - Enables penetration into small gaps and hairline cracks down to 0.2mm and larger on horizontal surfaces

• Centrifuges and Drop Forges - Supporting heavy dynamic equipment
• Hairline Crack Injection - Filling cracks from 0.2mm using gravity-fed methods or pressure injection down to 0.10mm
• Chemical Exposure Environments - Steelworks, refineries, electroplating works, and chemical plants
• Vertical Anchoring Applications - Anchoring starter bars and hold-down bolts (refer to Fosroc Epoxy Anchoring Application Guidelines)

Supply Formats

Conbextra EP10 is supplied in three pack sizes as two-component systems:

300ml Pack

• Base Component (FC523125-200ML): 200ml
• Hardener Component (FC523124-100ML): 100ml

1.5L Pack

• Base Component (FC523125-1L): 1L
• Hardener Component (FC523124-500ML): 500ml

15L Pack (largest size)

• Base Component (FC523125-10L): 10L
• Hardener Component (FC523124-5L): 5L

Mixing Instructions

Procedure:

1. Pour all contents of the hardener pack into the base container
2. Mix using a slow speed power mixer until homogeneous
3. Mix for two minutes or until uniform colour is achieved in the grout

Placing Instructions

• Pouring Method - Pour mixed grout steadily from one side only to eliminate air entrapment
• Small Gap Application - With the 300ml kit size, a nozzle is provided for squeezing or pouring into small gaps or hairline cracks above 0.2mm
• Continuous Flow - Ensure continuous grout flow is maintained
• Timing - Sufficient grout must be available prior to starting; regulate pour time to batch preparation time

Note: Refer to the Conbextra Epoxy Grouts Application Guide for further information.

Flow Characteristics

The maximum distance of flow is governed by:

• Gap thickness
• Head of grout applied
• Ambient temperature

Temperature Limitations and Storage

During Application

• Standard Conditions - Grouting may be carried out without special precautions at ambient temperatures from 5°C to 25°C
• Exothermic Reaction - All epoxy systems develop a temperature rise on mixing; place immediately after mixing without holding in bulk or re-lidding the container

In-Service Performance

• Frost and Sub-Zero Resistance - Resistant to frost and sub-zero temperatures
• Service Temperature Range - Suitable for in-service use up to 45°C

Storage

• Shelf Life - 3 years from date of manufacture if kept in dry, cool storage in original, unopened packaging
• Storage Conditions - Keep in original, unopened packaging in dry, cool conditions

Cleaning and Disposal

• Tool Cleaning - Clean all tools and equipment immediately after use with Fosroc Solvent 10
• Spillages - Absorb with sand or sawdust and dispose in accordance with local regulations

Safety Information

• A Safety Data Sheet (SDS) is available from the Fosroc website and must be read before use
• In emergency situations, contact any Poisons Information Centre (phone 13 11 26 within Australia) or a doctor for advice
• Application or performance data may change over time; consult current documentation before use
