Fennosize KD products are easy-to-use anionic or cationic alkyl ketene dimer (AKD) dispersions. They provide excellent paper machine runnability and efficient, fast and even sizing for various paper and board grades, such as high-quality fine paper, printing paper and packaging boards.
Fennosize KD sizes can be used in moderately acidic, neutral and very alkaline processes, even at a pH of 10. AKD is the only sizing agent providing resistance to lactic acid and it is used when a hard degree of sizing is needed. Kemira’s own AKD wax and size production facilities allow flexibility in the supply of optimal solutions for each customer’s individual needs.
