Use Megapoxy HICB for: Backing and reinforcing crusher liners, and grouting heavy machinery in mining and quarrying applications.
Megapoxy HICB is a two-component, 100% solids, high-strength epoxy grout formulated for the demanding conditions of mining and quarrying. It's specifically designed for backing and reinforcing metal liner plates in crushers and mills, as well as for chocking and grouting heavy machinery. Available in both Standard and Accelerated versions, Megapoxy HICB provides a solution for projects requiring either extended working time or rapid return to service. Its exceptional impact strength and compressive strength (115 MPa) protect valuable equipment from the severe forces encountered in crushing operations. The flowable nature of this grout ensures complete filling of voids, providing maximum support and stability. Megapoxy HICB is VOC-free, contributing to a safer working environment.
Primer Information: Metal surfaces must be thoroughly prepared by grit blasting to AS CK 9.4 - 1964 Class 3 finish. If grit blasting isn't possible, mechanically abrade the surface to a clean, bright metal finish and degrease. Using a putty (such as Megapoxy PF Rapid Set Putty) to seal crevices is essential to prevent leakage.
Cure Time:
- Standard: Work time is 30 minutes at 25°C, with cure times of 48 hours at 15°C, 24 hours at 25°C, and 12 hours at 35°C.
- Accelerated: Work time is 10 minutes at 25°C, with cure times of 12 hours at 15°C, 6 hours at 25°C, and 3 hours at 35°C.
Coverage Rate: Coverage depends on the volume of the space being filled. The flowable nature of Megapoxy HICB ensures efficient filling of voids and gaps.
Application Temperature Range: The minimum application temperature for both versions is 10°C. Application at higher temperatures will reduce the working time and cure time.
Chemical Properties: Megapoxy HICB exhibits excellent chemical resistance, crucial for the harsh environments in mining and quarrying. It is VOC-free, complying with Australian safety regulations.

Frequently Asked Questions About Megapoxy HICB
Q: What is the difference between Megapoxy HICB Standard and Accelerated?
A: The primary difference is the cure time. The Accelerated version is designed for faster curing, reducing downtime. At 25°C, the Standard version has a work time of 30 minutes and a cure time of 24 hours, while the Accelerated version has a 10-minute work time and a 6-hour cure time.
Q: How important is surface preparation for Megapoxy HICB?
A: Surface preparation is critical. Metal surfaces must be clean, dry, and abraded to ensure a strong bond. Grit blasting is the preferred method, but mechanical abrasion is acceptable if grit blasting is not possible.
Q: Can Megapoxy HICB be used for applications other than crusher backing?
A: Yes, while designed for crusher backing, it's suitable for other heavy-duty grouting applications in mining and quarrying, such as machinery chocking and anchor bolt setting.
Q: What are the mixing requirements for Megapoxy HICB?
A: The entire kit should be mixed thoroughly using a low-speed electric mixer for at least 2 minutes. Ensure to scrape the sides and bottom of the container to achieve a uniform mix. Avoid aerating the mixture.
Q: What precautions should be taken when working with Megapoxy HICB in hot weather?
A: In hot weather, store the kits in a cool place before use. High ambient temperatures will significantly reduce the working time, so prompt application is essential.
Q: Is Megapoxy HICB resistant to chemicals?
A: Yes, Megapoxy HICB exhibits excellent chemical resistance, making it suitable for the harsh chemical environments often found in mining and quarrying operations.
