Hydrolyzing XIRAN®: creating various anionic salts ammonium SMA most frequently used as dispersant, surfactant and + 2 NH3 binder in: O O O O - Wax & paraffin emulsions - O NH2 O - Pigments & inks dispersions + NH4 - Surface sizing - Specialty coatings - Adhesives formulations but also other salts can be + 2 NaOH used such as: O O O O sodium (or potassium) - - O O O Na+ Na+ SMA typically used for more hydrophilic systems

It has anti-bacterial effect and therefore has a fit as binder in O O Nanti-fouling coatings O H3CAcetic acid is used in this example as counter ion. Other acids can be -used as well.
