Applications

1. Neutral And Alkaline Papermaking: It works at neutral to alkaline pH, so the sheet can be sized without the acid rosin system and calcium carbonate can be used as a filler, which is why fine paper and cultural paper production moved to AKD neutral sizing, and it also suits closed water circuits.

2. Packaging Board And Food Contact Use: as a paper and paperboard adjuvant, limited to 0.4 percent by weight of the paper or paperboard for the dimer together with its dialkyl ketone hydrolysis products.

3. Recycled Fibre, Containerboard And Surface Sizing: It sizes recycled old corrugated container pulp and linerboard under neutral and alkaline conditions, is used on specialty grades that require heavy sizing, and can also be applied at the size press for surface sizing of coating base paper, normally together with cationic starch and a retention aid.

4. Wax And Emulsion Supply Forms: It is supplied as a waxy solid melting between 40 and 60 °C for on site emulsification and as a ready to use cationic aqueous emulsion, the sizing continues to develop as the sheet cures after drying and cooling, and the same reaction is used outside papermaking to hydrophobise wood and other fibre substrates.
