Paper Sizing Agent

Enhance paper performance with our high-quality paper sizing agents, including AKD, ASA, and surface sizing chemicals—improving water resistance and printability.

The problem

What Goes Wrong Without It

Sizing decides whether a sheet repels water or drinks it. Get the AKD emulsion, its emulsifier and its curing conditions wrong and you pay for it twice - once in Cobb values that miss spec, once in reel edges that size unevenly.

What we supply

How The Range Answers It

CHEMSUM supplies the whole AKD chain rather than one link of it: wax, high polymer emulsifier, ready-to-use liquid emulsion, curing agent, plus cationic rosin size for acidic and weakly neutral systems and an anionic surface size for the size press.

All 8 Paper Sizing Agent Grades

AKD Curing agent supplied by CHEMSUM in labelled export packaging
Paper Sizing Agent

AKD Curing agent

AKD that has not fully cured leaves sizing developing for days after the reel, and edges that size differently from the middle.

AKD Emulsion supplied by CHEMSUM in labelled export packaging
Paper Sizing Agent

AKD Emulsion

Acid rosin systems corrode the machine and lose sizing over time; a neutral system needs an emulsion that stays fine and stable.

AKD Wax supplied by CHEMSUM in labelled export packaging
Paper Sizing Agent

AKD Wax

Emulsifying your own AKD only pays if the wax purity and particle size are consistent.

What information do you need to quote?

The paper grade, the furnish, your system pH and the property target. That is enough to shortlist a grade and suggest a starting dosage.
