Combat Build-Up. Enhance Flow. Extend Equipment Life.
The Problem: Moisture-Driven Build-Up and Corrosion
In industrial environments, materials like coal, sulphur, cement, and phosphates are stored and transferred through silos, hoppers, feeders, and rollers. The moisture content of these materials can fluctuate significantly due to environmental and process-related factors.
When moisture increases, fine particles become sticky and begin to adhere to internal surfaces—especially in older silos made of steel or concrete. This causes:
- Flow blockages and inconsistent discharge
- Increased downtime for cleaning and maintenance
- Accelerated corrosion and erosion of the structure
- Long-term structural degradation and risk of unplanned outages





The Solution: Duromar® EAC / EAC-LV Epoxy Lining System
Arudra Engineers offers a proven lining solution using Duromar® EAC or EAC-LV—a high-performance epoxy coating applied at just 1mm thickness. It creates a smooth, non-stick, and corrosion-resistant surface ideal for the interiors of bunkers, silos, and hoppers. This coating prevents the sticking of bulk solids, resists acid attacks (especially from sulfuric acid due to moisture in sulfur or coal), and works effectively on both concrete and steel. By protecting against metal loss and structural decay, it enhances equipment lifespan, reduces maintenance frequency, and minimizes unplanned shutdowns.
HOW
IT WORKS ?
Duromar® HAR
Duromar® HAR is a trowelable bonding and protective putty designed to withstand high abrasion and impact. It performs exceptionally well in environments with fine coal dust, slurry, or ash particles, offering durable surface protection.
Duro-Tile sheets
Duro-Tile sheets, arranged in a hexagonal layout, are embedded into the HAR layer to form a tough ceramic barrier. This long-lasting surface prevents direct contact between abrasive materials and the underlying metal, extending equipment life.

Thermal and Captive Power Plants
Steel and Metallurgical Plants
Fertilizer and Chemical Industries
Cement and Mining Operations
The Duromar® lining system is ideally suited for industries with aging material handling infrastructure, providing long-lasting protection and reducing the need for frequent repairs. It is particularly effective for older silos and bunkers where ongoing patchwork is no longer viable or economical.
