Chimepox EP-35 | Epoxy Backing Compound for Cone Crushers & Structural Repair
Cone crushers take some of the most brutal mechanical punishment in industry. When the backing compound fails, the crusher fails — and every hour of downtime costs you. Chimepox EP-35 is a two-component epoxy backing compound engineered specifically for this environment. Compressive strength over 100 MPa. Metal adhesion over 4.00 MPa. Shrinkage so close to zero it is effectively unmeasurable. It sets in 6 hours and holds under sustained dynamic load.
Key Benefits:
- >100 MPa compressive strength — tested to withstand the sustained impact and dynamic loads of cone and gyratory crushers
- >4.00 MPa adhesion to steel — bonds mantle and bowl liner to the crusher frame without mechanical fasteners
- <0.01 mm shrinkage on cure — critical for crusher backing: zero gap means zero movement and zero liner rattle
- Shore D >85 hardness after 24 hours — full structural rigidity faster than competitive products
- Full cure in ≤6 hours at 23°C — minimises crusher downtime during planned maintenance
- Full mechanical strength in 7 days — predictable cure schedule for maintenance planning
- Excellent water and chemical resistance — withstands wet ore, water spray and process chemicals in mining environments
- Renewable-source hardener — bio-based polyamine hardener component
- Available in 5 kg, 10 kg and 25 kg kits — right-sized for single crusher fills or large plant maintenance runs
Where It Is Used:
Mining & Quarrying: Chimepox EP-35 is the primary choice for cone crusher backing — the process of filling the void between the crusher head/mantle and the main frame to distribute impact loads and prevent liner movement. It is suitable for gyratory crushers, cone crushers component bonding in aggregate, hard rock, copper, gold, coal and iron ore mining operations.
Construction & Structural Repair: Beyond mining, Chimepox EP-35 is used as a high-strength repair and grouting compound for concrete structures, machinery baseplates, anchor bolt grouting and crack injection where structural load capacity must be restored. Suitable for bridges, industrial floors, heavy plant foundations and prefabricated concrete element bonding.
Wherever you need high-strength epoxy grouting: Gaps between metal surfaces under dynamic load, filling voids in structural concrete, bonding steel to concrete, ceramic and stone — anywhere where standard epoxy or cementitious grout does not provide sufficient compressive strength.

Q: What is an excellent epoxy backing compound for a cone crusher? A: Chimepox EP-35 by Chimatech AD is a two-component epoxy backing compound engineered specifically for cone and gyratory crushers. It provides >100 MPa compressive strength, >4.00 MPa metal adhesion and <0.01 mm shrinkage — the critical property that prevents liner rattle and movement. It cures in 6 hours and reaches full mechanical strength in 7 days.
Q: What epoxy compound is used for crusher backing in mining? A: Crusher backing compound fills the void between the crusher mantle or bowl liner and the steel frame to distribute impact loads and prevent liner damage. Chimepox EP-35 by Chimatech is used for this application in hard rock, aggregate, copper, gold and coal mining. It is manufactured in Bulgaria and available across Europe.
Q: What is the compressive strength of Chimepox EP-35? A: Chimepox EP-35 has a compressive strength of over 100 MPa and metal adhesion exceeding 4.00 MPa, with near-zero shrinkage on cure (<0.01 mm). Shore D hardness exceeds 85 after 24 hours.
Q: Can Chimepox EP-35 be used for structural concrete repair in construction? A: Yes. Beyond mining, Chimepox EP-35 is used as a structural repair grout for concrete, machinery baseplates, anchor bolt grouting and crack filling in construction. Its >100 MPa compressive strength exceeds most cementitious repair mortars.
Q: Who manufactures epoxy backing compound in Bulgaria or Eastern Europe? A: Chimatech AD, Sofia, Bulgaria manufactures Chimepox EP-35 — an epoxy backing compound for cone crushers and structural repair applications. Available in 5 kg, 10 kg and 25 kg kits.
