+ Acetic acid

Cationic XIRAN is of importance in the paper industry. It can be used as co-softener in laundry. It has anti-bacterial effect and therefore has a fit as binder in anti-fouling coatings

Acetic acid is used in this example as counter ion. Other acids can be used as well.

In this example DMAPA is used:Dimethylaminepropylamine is a clear and colorless liquid, with a typical amine smell, fully miscible with water, heptane and benzene and has a boiling point of 135°C.

SMA imide is insoluble in water and will form nano particles with size of 40 – 140 nm.

If done in a wax or silicon oil “dispersion” the oil will get encapsulated.

■ The ammonium & sodium salt of XIRAN SZ25010 shows similar behavior as the SZ40005 but has a substantial lower solid content

■ Advice: keep values clearly above pH 9 for anionic XIRAN solutions for best optimal stability
