In high-speed papermaking, everything happens in a split second.

As the pulp slurry rushes through the system, fiber and filler are constantly challenged by intense shear forces. Without strong bonding, valuable materials—especially fine fillers—are easily washed away with water before they even become part of the paper sheet.

This is where retention becomes critical. Because the more you lose in that first pass, the more you lose in cost, efficiency, and consistency.

EXCELBOND® 40 changes that dynamic. Its high molecular weight provides excellent resistance to shear, helping fiber and filler stay bonded even under high-speed conditions. 

And most importantly, it unlocks the full potential of high-filler formulations of the papermaking process AND reducing cost without compromising performance.

The result is a more efficient process: more materials retained, faster dewatering, and smoother machine runnability.
