| Item | Details |
|---|---|
| Material Options | Two-part, 100% solids resilient epoxy composite for gyratory and cone crusher backing |
| Typical Properties and Acceptance Criteria | Requires low volumetric shrinkage, compressive load capacity, impact absorption, adhesion to steel and iron, and controlled exothermic curing. For example, the manufacturer gives a typical dry service range of approximately -28°C to 104°C for LOCTITE PC 9465. Final selection also requires checks of working time, curing temperature, pour thickness, removal procedures and safety data. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
