Alkyl Ketene Dimer (AKD) — Neutral Paper Sizing Agent
Alkyl ketene dimer is a reactive internal sizing agent used in neutral and alkaline papermaking to control water and liquid penetration into the sheet. Allzone supplies AKD to Canadian mills with the grade confirmed against supplier documentation before quotation.

Technical & procurement detail
Functional role of alkyl ketene dimer (akd)+
AKD reacts with cellulose hydroxyl groups to form a covalently bonded hydrophobic layer on the fibre. Because it works at neutral to alkaline pH, mills can run calcium carbonate filler — impossible with acid rosin sizing — while still meeting Cobb and liquid penetration targets on the finished sheet.
Selecting the right grade+
Emulsion solids, promoter system and stabiliser package define the grade, and sizing response depends heavily on retention chemistry and machine conditions. Furnish, pH, filler loading, machine speed and target size level determine what is quoted.
Documentation and specification+
Properties differ between producers and between grades of the same material. Allzone confirms the applicable grade with the supplier before quoting and shares the technical data sheet and safety data sheet for the exact material offered, so the values you evaluate are the values you receive.
Frequently asked questions
How does AKD differ from rosin sizing?+
Rosin size works in acid systems with alum; AKD reacts with cellulose and works at neutral to alkaline pH, allowing calcium carbonate filler use. Sizing develops over time after the reel rather than fully on the machine.
Which grade will I be quoted?+
The grade is set by your specification. Share the target performance, process conditions and any customer or regulatory requirement in the RFQ and the matching grade is confirmed with the supplier before quotation.
What packaging is available?+
Packaging is confirmed with the supplier at quotation for the grade and quantity discussed.
Can you deliver across Ontario and Quebec?+
Yes. LTL and FTL freight is arranged across Ontario, Quebec and Western Canada, with container-direct supply for repeat volumes.
