Paper Sizing Agent (AKD Emulsion) CAS#37187-62-5
Powerful Sizing & Water Resistance Capacity: Alkenyl succinic/alkyl ketene dimer based internal sizing agent with excellent hydrophobic performance, widely used to improve water resistance, ink resistance and printability of paper and paperboard.
High Retention & Fast Curing Property: Good compatibility with cationic retention and drainage aids, fast curing after paper machine drying, low dosage and high sizing efficiency for different paper grades.
Stable Liquid Form for Convenient Transport: Milky white to pale yellow liquid with uniform texture, stable under sealed cool storage, easy for metering, pumping and automatic feeding.
Paper sizing agent, mainly AKD or ASA emulsion, is a high-demand papermaking auxiliary raw material, low irritancy and wide coverage of writing paper, packaging paperboard, newsprint and special paper application scenarios.
