In anilox roll coating, chromium oxide (Cr₂O₃) powders are the go-to materials for achieving smooth, hard, and wear-resistant surfaces. But not all Cr₂O₃ powders are created equal.

Saint-Gobain Coating Solutions offers two optimized chromium oxide powders, #4040 and #4041,  each designed to serve distinct operational goals.

Learn more about our #4000 powder series by exploring the technical data sheets and related products.

If your top priority is maximizing throughput while maintaining reliable coating quality, #4040 is your best ally. This powder is engineered for production-intensive environments and high-thickness coatings, where cost efficiency and spray time are key metrics.

Why #4040?

• High Deposition Efficiency : delivers excellent deposition rates, especially at high feed rates, leading to faster processing times and reduced downtime.
• Energy-Efficient Coating Process : when paired with the ProPlasma HP torch, #4040 enables coating with energy consumption as low as 14.5 kWh/kg, significantly lower than conventional systems (35.5 kWh/kg).
• Anilox-Compliant Microstructure : produces dense, coherent coatings with good adhesion and low porosity, ensuring engraveability and smooth ink transfer.
• Stable Spray Behavior : optimized flowability for consistent performance across batches.
• Ideal for Large Rollers : shortens spray times and allows high-thickness coatings for long roll operations.

Recommendation

#4040 is ideally suited for high-throughput flexographic or gravure print environments. If your facility prioritizes OEE (Overall Equipment Effectiveness, this powder enables fast, reliable, and energy-efficient performance. It’s a productivity-first solution that supports consistent quality without the burden of excessive energy or maintenance costs.

If your operational priority leans toward precise engraving, optimized durability/coating thickness ratio, and coating robustness under aggressive conditions, #4041 is the powder to choose. It is optimized for delivering fine screen ruling engraving with dense, long-lasting coatings that can handle high mechanical loads and abrasive conditions with minimal degradation over time. However, this is balanced by lower deposition efficiency.

Why #4041?

• Dense and Homogeneous Coatings: Creates compact microstructures with uniformly distributed fine pores, ideal for precise engraving and resisting wear and ink entrapment.
• Extended Roller Lifespan: Optimization of roller durability at lower thickness for precise printing without compromising durability.
• Best for Small Rollers: Particularly beneficial in high line screen counts with tight tolerance, precise engraving and high resistance on conventional thickness.

Recommendation

#4041 is the go-to solution for high-precision printing with long-life coating needs in high-stress applications. This powder ensures minimal downtime and maximum performance

Both powders are specifically suited for use with the ProPlasma HP torch, a high-performance thermal spray system developed by Saint-Gobain Coating Solutions. The system’s unique single-electrode design ensures improved arc stability allowing consistency across coating cycles, even after maintenance thanks to self-aligning technology. Additionally, it offers the flexibility of switching between all HP and STD spray modes, helpful when coating various type of pieces and, materials including chromia for both large and small rollers using the same setup.

Saint-Gobain’s solution simplifies the coating workflow without compromise in performance:

• High-Productivity coating process
• No bond/topcoat configuration changes needed between jobs
• Fast maintenance cycles without removing the gun from the robot
• Energy savings and lower total cost of ownership
