Megapoxy HICB is a heavy-duty, 100% solids epoxy grout specifically engineered for backing metal liner plates and reinforcing structural gaps in primary gyratory and cone crushers. It delivers a massive 115MPa compressive strength and a 7.7Gpa modulus of elasticity, providing the necessary shock-absorption to prevent catastrophic liner movement and structural fatigue under intense repetitive pounding.
This flowable system achieves a 20MPa tensile bond to grit-blasted steel, ensuring a permanent, void-free fit that eliminates dangerous stress concentration points. For high-output operations, the Accelerated version allows a rapid return to service with a 6-hour cure time, protecting critical assets while minimizing machinery downtime.
Frequently Asked Questions
What is the main difference between HICB Standard and HICB Accelerated?
The primary difference is cure speed. At 25°C, the Standard version has a 30-minute work time and 24-hour cure, suitable for planned maintenance. The Accelerated version has a 10-minute work time and 6-hour cure, designed for rapid return-to-service during critical shutdowns.
What is the maximum thickness I can pour Megapoxy HICB in a single layer?
The recommended maximum casting thickness is 50 mm per pour. This is to control the exothermic reaction (heat generation) during curing. For filling larger voids, you must pour in multiple 50mm layers, allowing the previous layer to harden before topping up.
How critical is temperature when using HICB?
Temperature is very critical. The minimum application temperature is 10°C. High ambient temperatures will significantly shorten the usable work time. It is crucial to store kits in a cool place before use and be prepared to work quickly in hot conditions, especially with the Accelerated version.
Can HICB be used for other applications besides crusher backing?
Yes. Due to its extremely high compressive strength and excellent bond, it is also a premium solution for grouting heavy machinery bases, chocking machinery, setting high-load anchor bolts, and rail track grouting where maximum strength and vibration damping are required.

Applying Megapoxy HICB: Enhanced Protocols & Best Practices
-
Step 1: Preparation & Sealing
Ensure all metal surfaces are prepared as per the adhesion guide. Critically, seal all crevices, joints, and pour spouts to prevent leakage of the flowable grout.
Sealing Method
Use a fast-setting putty, such as Megapoxy PF, to create dams and seals. Check thoroughly for any potential leak paths before proceeding to mix.
Pro Tip: If ambient temperature is high, cool the kits by storing them in a cool room or shaded area prior to mixing. This will maximise the available work time. -
Step 2: Professional Mixing
Pour the entire contents of the Part B hardener into the Part A resin pail. The product is supplied in a pre-metered kit; do not use partial mixes.
Mechanical Mixing
Using a low-speed electric mixer (under 400 RPM), mix for a minimum of 2 minutes. Stop, scrape the sides and base of the bucket thoroughly, then mix for at least another 1 minute until the colour is perfectly uniform and streak-free.
Pro Tip: Do not "whip" or aerate the mixture. Keep the mixing paddle submerged to minimise air entrapment, which can create voids in the cured backing. -
Step 3: Pouring & Curing
The mixture must be used immediately after mixing is complete. Pour steadily into the void from one location to allow air to escape.
Layered Pours
Do not exceed a pour thickness of 50mm. For deeper voids, allow the first layer to harden before applying the next. This manages heat and ensures a full cure.
Curing: Allow the HICB to harden completely before returning the crusher to service. Refer to the cure time chart for your specific ambient temperature and product version (Standard or Accelerated).
Limitations & Safety
Product Limitations
Maximum casting thickness is 50 mm per pour. Exceeding this can lead to excessive heat generation (exotherm) and potential cracking.
Minimum application temperature is 10°C. Curing will be significantly delayed below this temperature. High ambient temperatures will greatly shorten work life.
For Professional Heavy Industrial Use Only. This product is a hazardous material with specific application requirements. It must not be used outside its intended purpose by untrained personnel.
Safety & Handling Requirements
Personal Protective Equipment
Mandatory: Wear chemical-resistant gloves (nitrile rubber), chemical goggles or face shield, and impervious protective clothing. Part A is corrosive and can cause severe skin burns.
Ventilation Requirements
Ensure ventilation is adequate to maintain air concentrations below exposure standards. Use with local exhaust ventilation. Do NOT enter confined spaces where vapour may have collected.
Handling & Storage
Store locked up in a cool, dry, well-ventilated place away from foodstuffs and ignition sources. Avoid all eye and skin contact. Do not eat, drink or smoke when using this product.
Emergency First Aid
Eyes:
Immediately hold eyelids apart and flush continuously with running water for at least 15 minutes. Urgently seek medical assistance. Can cause corneal burns.
Skin:
This material is toxic and can be absorbed through skin. Immediately drench with water, remove all contaminated clothing, and flush skin with running water for 15 minutes. Seek urgent medical help.
Inhaled:
Remove victim from exposure to fresh air. Keep at rest in a comfortable position. Seek medical advice if effects persist.
Swallowed:
Toxic if swallowed. Rinse mouth, do NOT induce vomiting. Give a glass of water. Immediately call a Poisons Centre or doctor.
Refer to the Safety Data Sheet (SDS) for full details. This is a hazardous substance requiring strict handling protocols.
Substrate Adhesion & Preparation Guide
Steel (Manganese, Carbon, and Fabricated)
Surface Preparation
Bonding surfaces must be 100% free of all contaminants, including old backing material, rust, grease, oil, and moisture. Grit blast surfaces to a Class 3 bright metal finish (AS CK 9.4-1964) for maximum adhesion. If blasting is not possible, use mechanical grinders to achieve a clean, bright, and profiled surface.
Primer Requirements
No primer required
Megapoxy HICB is designed for direct, tenacious bonding to correctly prepared metal substrates. No primer is necessary. Focus all effort on achieving a perfectly clean and profiled surface.
