Fusion™ is a liquid cross-linking additive supplied as a low-viscosity emulsion for corrugating starch or flour adhesives.

After neutralization with a suitable base (e.g., NaOH), Fusion forms a controlled aqueous network inside the adhesive, taking over the rheological role normally provided by the pre-cooked carrier.

• Supports up to 100% replacement of the pre-cooked carrier portion of starch-based formulations.

• Engineered to perform in high-pH environments typical of corrugating kitchens.

What it does in the adhesive

When dosed into water-based starch or flour adhesives, Fusion delivers:

• Very stable viscosity over time and after standstill/weekends.

• Strong shear-thinning / pseudoplastic behavior with thixotropic recovery.

Thixotropy: viscosity decreases under shear and recovers when shear is removed—ideal for fast film formation and quick set at the nip.

Why this matters on the corrugator

• The Glue & Doctor rolls generate high shear; viscosity drops instantaneously, forming an extremely thin, uniform glue film—often at mechanical minimum settings.

• At paper contact, shear stops and viscosity recovers immediately, enabling precise fiber penetration at the flute tip and strong bonding.

• Glue rolls typically run at ~98% of board speed (≈ 200–400 m/min), and Fusion helps maintain film control at these speeds.

Result: lower glue consumption, consistent bonding, and a cleaner, more controllable process—while enabling the use of native starch and the reduction or full replacement of carrier in the recipe.
