Roll Armor® Ceramic Coatings Protect Your Rolls, Your Product and Your Bottom Line

The paper industry is changing. McKinsey & Company reports, "Packaging is growing all over the world, along with tissue papers, and pulp for hygiene products. Although a relatively small market as yet, pulp for textile applications is growing. And a broad search for new applications and uses for wood and its components is taking place in numerous labs and development centers."

To meet the demand of the changing market, mills need to produce more high quality product. They must find ways to produce faster while maintaining high quality and reducing downtime to keep up with demand for packaging grades, coated board, tissue, newsprint, office paper, and more.

Replacing rubber covers with a high quality ceramic coating not only retains the original surface quality of your rolls, but also reduces the time and cost of maintenance and unplanned downtime.

Roll Armor®, the preferred roll coating in North America, is a proprietary system that extends the life of your rolls.

Key benefits of Roll Armor® ceramic coatings:

  • Improved paper quality via better release of stickies
  • Superior corrosion protection via proprietary 3-layer system
  • Greater product uniformity due to high coating density
  • High hardness of ceramic eliminates wet-end roll changes due to wear

Roll Armor® vs. rubber covers and other roll coating processes

Unlike rubber covers with an average product life of 1-3 years on many positions, Roll Armor ceramic coatings last for years! One PRG customer reports two decades and counting! It's proof positive that Roll Armor ceramic coatings provide the best value in the marketplace.

Since Roll Armor ceramic coatings are denser and harder than competitor coatings, they provide better corrosion protection with reduced thickness, thus offering more strength and durability on your roll surface. The cross-sectional coating images below illustrate the porosity of Roll Armor (left) vs. a competitor's ceramic coating (right). Note the large distribution of porosity (voids) in the competitor's product, which allows pathways for corrosive media to reach the roll substrate.

Additional benefits of Roll Armor®:

  • Easy to clean - the dense coat makes doctoring simple
  • Extended life of felt roll covers
  • Increased machine speed
  • Improved sheet profiles
  • Reduced maintenance costs
  • Rolls require fewer regrinds
  • Reduced downtime

Only PRG provides Roll Armor for the paper industry. A proprietary system, Roll Armor is guaranteed to retain your original roll surface, reduce maintenance and downtime, as well as protect your equipment, your product and your bottom line.
