Problems in Paper Making:

Build Up:
Stickies (contaminates from recycled paper)
Secondary Fiber
Sizing - starch from the size press
Coating applied to the paper: - example milk carton stock or other moisture barrier products.

Corrosion On Wet End:
Corrosion from Felt Cleaners - Caustic Boil Outs
Corrosion from chemicals added to process
Corrosion from wet process environment

Slippage On The Dry end:
Winding Issues.
Slippage on start up scratches the paper and contributes to loose core wrap.
Slippage causes telescoping of parent roll.
Slippage causing loose wrap of parent roll.
Slippage causing vibration on winder machine producing uneven wrap.
Reel fall away & bagging.
Traction issues on Rider Rolls that help maintain a "tight" wrap of Parent Roll.

Coating Properties Needed:
Traction / Release / Cleanability / Wear / Corrosion Resistance / Low COF

Release/Cleanability/Wear & Abuse Resistant:

Release/Cleanability/Wear & Abuse resistance/Corrosion Resistance:

Release, Low Friction, Wear:

Release/Traction:

Traction/Wear Resistance:

Thermal Spray Coatings for Boilers and Digesters:

Expect more life and better performance over weld overlay

Typical cost savings are arrived from:

Elimination or reduction of build - up issues results in:

• Less Sheet Breaks caused from contamination dropping into sheet path during operation resulting in less unscheduled down time & loss production.
• Less Sheet Breaks = Less "Broke" Produced = Less Re-pulping = Cost Savings
• Less Quality Issues from "snowballing" of contamination buildup on critical drums & rolls causing transfer issues affecting product appearance.
• Better drying capacity due to less contamination on dryer drums
• Less maintenance cost due to quicker cleanups during shut downs
