Anionic Surface Sizing Agent

Anionic Surface Sizing Agent – Improve Paper Strength and Surface Performance

Anionic Surface Sizing Agent is a water-based polymer emulsion specially designed for surface sizing applications in papermaking. It forms a uniform and dense film on the paper surface, significantly enhancing surface strength, water resistance, printability, and coating holdout. With excellent compatibility and easy application, it is ideal for improving the performance of various paper grades.

This product features strong film-forming ability and stable anionic dispersion, providing superior runnability and smoothness on the paper machine. It can be used alone or combined with starch, AKD, or ASA to further improve sizing and surface quality.

Key Features & Advantages:

• Enhances surface strength, water resistance, and printability

• Excellent compatibility with starch and other surface agents

• Improves coating holdout and reduces linting and dusting

• Provides stable operation and uniform film formation

• Suitable for both neutral and alkaline papermaking systems

Applications:

• Surface sizing for writing and printing paper

• Coated and base paper for packaging board

• High-grade cultural paper and specialty paper
