PRODUCT INTRODUCTION
Surface Sizing Agent is a high-performance papermaking auxiliary designed to improve paper surface properties, water resistance, liquid penetration resistance, printability and surface strength. It forms a uniform protective layer on paper surface and enhances final paper product performance.
This product is widely used in paper machines, pulp preparation, paper forming, surface sizing, board production and specialty paper production. It provides good sizing effect, water resistance, good stability, easy use, non-hazardous property and good compatibility.
Our surface sizing agent is produced under strict process control. It is available in different grades according to pulp type, paper grade, sizing requirement, water resistance target, pH range, machine speed and application system. Each batch is inspected for appearance, solid content, viscosity, particle size, sizing degree, water resistance and stability before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your papermaking system, machine condition and destination country regulations.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Insufficient Sizing Degree
Unsuitable grade, insufficient dosage, low coating amount or wrong pH causes poor sizing.
Solution: Select suitable grade, increase dosage, raise coating amount and control pH.
Poor Water Resistance
Unsuitable grade, insufficient dosage or wrong drying condition causes poor water resistance.
Solution: Use high water resistance grade, increase dosage and optimize drying condition.
Poor Printability
Unsuitable grade, wrong formulation or uneven coating causes poor printability.
Solution: Improve coating uniformity, select printability grade and optimize formulation.
Uneven Coating Result
Poor solution uniformity, low machine speed or unsuitable grade causes uneven coating.
Solution: Improve solution uniformity, adjust machine speed and select suitable grade.
Foam Problem
Unsuitable grade, high agitation or high surfactant causes foam generation.
Solution: Use low foam grade, reduce agitation and add anti-foam component.
Poor Compatibility with Starch
Wrong grade or incompatible starch causes precipitation or poor performance.
Solution: Test compatibility before production and select matching grade.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
High COD Load in Wastewater
High organic content or excessive dosage increases wastewater treatment load.
Solution: Optimize dosage, use concentrated grade and cooperate with wastewater treatment.
