Specification (properties incertificate of analysis)

Milky dispersion

pH (indiluted form):

5

Low viscous liquid:

<1000 mPa.s at 20 °C

using Brookfield

Functions to be recognised

Dispersant to dispers solid particles or liquid

droplets in continuous phase

Multi ancor points leads to strong (irreversible)

adsorption

Building of steric barrier and behaviour of

polyelectrolyte (electrostatic repulsion)

Reducing viscosity

Compatibility agent

Milling aids: easy grinding

Like Polyelectrolyte

Hydrophilic monomer

(AMPS) consists of sulfonic

group

High molar ratio of AMPS

provides high charge density

Sulfonic groups are neutralised (sodium salt);

full dissociation particularly in pH >7

Dispersion – Colloidal Solution

Sulfonic groups (in AMPS monomers) improve

solubility of copolymer in water,

Alkyl chains (in methacrylate monomers) improve the

adsorption and accumulation at polar/apolar interface

Due to relatively high molecular weight of copolymer ,

solubility characteristics of monomers and molar ratio

the aqueous colloidal solution is being produced

Application Product can be used in aqueous dispersions (mainly

aqueous suspension concentrate SC) or in preparation of

slurry to be spray dried

as dispersant or co-dispersant (in combination with

other polymer and/or traditional surfactant)

as milling aid

Application and Guides for SC

Usually 2-5 % Emulson AG/TP1 gives desired results (regarding suspension stability, rheological

characteristics)

Good compatibility with other anionic coformulants (phosphates, sulfonates)

Good compatibility with non-ionic alkoxylates (ethoxylates, EO/PO adducts)

Good compatibility with xanthan gum

SC Formulations of following Active Ingredients were examined obtaining

suitable results

Inorganic solid actives

Bordoeaux Mixture

Copper oxychloride

Sulfur

Organic solid actives

Diuron

Fluometuron

Bendiocarb

Advantages

High tolerance to extreme conditions of ionic

strength and temperature

Ideal for solvent-free aqueous system including

SUSPENSIONS (slurries)

Usualy no wetting agent required

Theta Conditions

Using NaCl (4M), CaCl2 (1M)and Na2SO4 (2M)

the salt tolerance is excellent: no flucculation,

precipitation occur

Heating up to 70 °C no flucculation and noincrease

in viscosity
