AKD is used for hydrophobization of paper, especially when made under alkaline conditions. AKD is widely used for liquid containers, inkjet papers, and many other grades of paper that need to resist water over a long period of time. Because AKD is received at the paper mill as a readymade, milky emulsion, it can be a very
