AKD Curing agent - Papermaking Additive

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

About AKD Curing agent

Our AKD Curing Agent is a specialized additive designed to accelerate the curing (esterification) reaction of alkyl ketene dimer throughout the drying and pressing stages. By promoting faster and more complete bonding of AKD to cellulose fibers, it ensures superior water resistance, roll stability, and long-term durability.

Key Features and Advantages

  • Enhanced Curing Efficiency — speeds up the esterification between AKD molecules and fiber hydroxyl groups, especially under moderate drying conditions
  • Improved Barrier Performance — helps form a denser and more uniform hydrophobic layer, boosting water repellency and reducing Cobb values
  • Better Roll and Slitting Stability — ensures uniform sizing towards roll edges and reduces “slug” or leveling issues
  • Reduced AKD Dosage — by improving reaction efficiency, lower AKD additions can achieve equivalent performance, offering cost savings
  • Compatibility — works well with common AKD emulsions, internal sizing systems, and other wet-end additives
  • Optimized for Alkaline Papermaking — stable under neutral to slightly alkaline pH, suitable for modern base paper systems

Applications

  • Neutral to slightly alkaline base paper systems
  • AKD internal sizing lines running under moderate drying conditions
  • Mills reducing AKD dosage at constant sizing performance

Packing and Supply

Liquid grades ship in IBC totes carrying net weight, gross weight, lot number, production date and expiry date on the label. Exact pack sizes and drum options are confirmed on quotation.

AKD Emulsion

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