Choosing the Right Roll Covering for Your Corona Treater

When considering a new corona treater, selecting the right roll covering can be overwhelming. To help you make the best choice for your application, here’s a quick comparison of two common options: silicone sleeving and ceramic coating.

Silicone Sleeving

Pros:

• Quick Replacement: When sleeving fails, it can be replaced immediately, minimizing downtime.
• Cost-Effective: Sleeving is an affordable solution, easy to keep on hand as a spare.

Cons:

• Susceptible to Damage: Operators often cut into the sleeving when trimming the web, leading to premature failure.
• Frequent Replacements: Sleeving needs more frequent replacement than ceramic coating.
• Installation Challenges: Installing sleeving on longer face rolls can be difficult and time-consuming.

Ceramic Coating

Pros:

• Durable: Resistant to damage from knives and web-cutting tools.
• Robust Construction: Offers greater resilience, reducing the need for frequent replacements.
• Long Lifespan: Typically lasts at least two years, with many coatings extending well beyond five years.
• Heavy-Duty Applications: Ideal for demanding environments and processes that require more robust solutions.
• Larger Rolls: Ceramic coatings can be implemented on larger outer diameter (OD) ground rolls, making them a great choice for larger applications.
• Enhanced Surface Energy: Ceramic coating raises the attainable surface energy (mN/m), enabling better adhesion and improved results in surface treatment processes.
• Enhanced Performance: Provides consistent performance over its lifespan, reducing operational interruptions.

Cons:

• Lead Time for Repairs: Strip and recoats come with a lead time of 4-6 weeks, which can cause delays if not planned for.
• Cost Considerations: Requires a spare roll in case of failure, adding to initial costs. However, these costs are often offset by the longevity of the coating.
