You can add AKD or ASA.

AKD is Alkyl Kitene Dimer.

ASA is Alkyl Succinic Anhydride.

AKD is very common and user friendly Water barrier. It is added @2% on oven dry or bone dry pulp.

Both are available as food grades and both are organic polymers soluble in water. Best performance effectiveness is at pH levels around 6.

Of course, both AKD and ASA are biodegradable.

Hi Tushar Udgata

Thanks for recommending AKD, I will definitely try it!

Could you be kind enough to recommend any suitable additive to improve the grease-barrier property of the pulp? Appreciate your response!

PFAS free Fluorocarbons are used by internal addition to pulp.( beater addition route)for grease resistance.

Coating additives are also available for grease resistance.
