About Cationic Rosin Sizing Agent
Cationic Rosin Sizing Agent is a modified rosin-based internal sizing chemical designed for acidic to neutral papermaking systems. It provides excellent hydrophobicity and improves paper water resistance, surface strength, and printability by forming a stable rosin–alum complex within the fiber network.
Compared with traditional anionic rosin sizes, this product features a cationic modification that enhances retention on fibers and improves sizing efficiency, even under conditions with lower aluminum sulfate dosage. It ensures uniform distribution, stable performance, and reduced sizing reversion during storage or high-speed paper production.
Key Features and Advantages
- Excellent internal sizing performance and water resistance
- Strong fiber affinity and high retention efficiency
- Effective under acidic and weakly neutral conditions
- Improved sizing stability and reduced dosage of alum

Other Paper Sizing Agent Grades
AKD Emulsifier
An AKD emulsion that coagulates in storage or drifts in particle size wastes wax and sizes unevenly.
AKD Emulsion
Acid rosin systems corrode the machine and lose sizing over time; a neutral system needs an emulsion that stays fine and stable.
Anionic Surface Sizing Agent
Linting, dusting and poor coating holdout at the size press show up as print defects downstream.
