Hercobond™ Plus Dry Strength Additives

Hercobond Plus is an advanced microparticle dry strength technology. This family of products includes several dry strength additives that enhance the end-use performance of a variety of paper and paperboard packaging grades. The technology provides high levels of direct strength and offers a range of configurations that give you ultimate flexibility to design the most cost-effective program for your mill.

In addition to managing dry strength characteristics, Hercobond Plus enables packaging producers to develop new grades and, in many cases, improve the operating efficiency of their machines. Key benefits of Hercobond Plus dry strength additives include:

PERFORMANCE

  • Improved dry strength
  • Reduced basis weight
  • Improved productivity
  • Increased effectiveness in a broad range of furnishes
  • Improved retention and drainage

SUSTAINABILITY

  • Increased recycled fiber utilization
  • Expanded production capabilities, including lighter-weight grades
  • Reduced fiber and energy costs
  • Reduced shipping / freight
  • Improved machine cleanliness

Onsite Production for Superior Performance

Hercobond Plus is not a soluble polymer; it is a microparticle that is created through a patented process at our customer sites. The building blocks for this technology are shipped to our customers at very high solids, which reduces freight and lowers the carbon footprint. The onsite process produces a truly differentiated microparticle dry strength technology that enables higher performance.

The process begins with the manufacture of a unique, high-molecular-weight polyacrylamide (PAM). Once onsite, the PAM is functionalized, creating highly reactive aldehyde groups. The resulting microparticle is easily retained within the fiber network, providing increased strength through covalent bonding. The microparticle structure is much larger than a soluble polymer and results in improved retention and direct strength performance. In addition, the structure of the microparticle results in a chemistry that is less affected by wet-end interferences from high anionic trash, soluble lignin and conductivity. This leads to a flexible technology that is effective over a broad range of furnishes, including recycled, virgin kraft and high-yield pulps.

Hercobond Plus programs can be tailored to your mill’s unique environment. As a result, Hercobond Plus dry strength additives deliver supreme flexibility in most wet-end systems, offering the highest performance at the lowest possible cost.
