  GRCR-04
  Cationic dispersed rosin size is a high decentralized rosin size with positive charge. It is white lotion in appearance, contains 100% free rosin, has medium charge density, can be diluted freely with water, has good mechanical stability, low cost, and is easy to use.

   

  Key Properties

   

  Strong Adhesion: Bonds well with paper, metal, wood, etc.

  Water Resistance (especially modified): Reduces fiber absorbency in papermaking.

  Oxidation-Prone: Natural rosin may become brittle when exposed to air, requiring antioxidants.

  Eco-Friendliness: Natural rosin is biodegradable, but some modified products may contain toxic solvents.

  

  
  
  Papermaking Industry (core use):
          Sizing Agent: Added to pulp or coated on surfaces to improve water and strength resistance.
          Used with Aluminum Sulfate: Rosin size binds with aluminum ions under acidic conditions, adhering to              fibers.
  
  Adhesives:

•         Used in low-demand bonding (e.g., labels, carton sealing), often blended with rubber or synthetic resins.
  Inks & Coatings:
•         Acts as a film-forming agent or tackifier, enhancing gloss and adhesion.
• Others:
•         Flux in electronics, rubber tackifier, etc.

  Functional mechanism:
   

  Cationic rosin size can retain itself on the fiber due to its positive charge. It has a high retention rate and low sizing dosage. Since the rosin particles attached to the fiber surface only need to react with aluminum ions in the drying section of the paper machine, there is less demand for aluminum sulfate. Compared to anionic rosin gum, it will not scale or form sediment with metal particles such as calcium and magne-sium in the system.
