Technical Service

Patcham – A Solution Provider

The dispersion process involves 3 stages:

1. Wetting

2. De-agglomeration

3. Stabilization

Pigment dispersion process

Additives

12


Dispersing medium

Wetting agents

Entrapped airAgglomerates

Pigment covered with wetting agent

During the wetting step, air and moisture occurring on the pigment surface are driven off and replaced by the liquid of

the mill-base

Wetting:

Pigment dispersion processDe-agglomeration:

During this step, the pigment agglomerates are broken up by energy input and accordingly reduced in size.

This mechanical separation can be achieved by dissolvers or different types of mills ‘Grinding’. The amount and the duration of the energy input are the main factors for a complete separation of primary pigment particles

DLVO THEORY

• Derjaguin, Landau and Verwey, Overbeek: stability of lypophobic colloids

• The best separation distance between two particles is atbest at the critical distance or even better at wherecombination of both attraction and repulsive forces is atzero

Waterborne latex paints & related products

• Polyelectrolytes

– Additives used for dispersion in waterborne systems

• High molecular weight products containing electrical charges in side chains

– Polyphosphates

– Polycarboxylates


Steric or Entropic Stabilization

18

Main stabilization in apolar systems

Dispersant Requirements:- Contains affinic groups providing strong adsorption on pigment surface.- Resin/solvent compatible chains directed into the surrounding vehicle.



ΔDa: distance at which particles agglomerate

Conventional polymeric dispersants: low volume per mass

(Relatively) low layer thickness of the adsorbed layer cannot prevent attractive forcesto dominate stabilizing forces: agglomeration

adsorption layer cannot prevent agglomeration …

New:

High Molar Volume Dispersant Technology

High Molar Volume Polymers • The high molar volume dispersants technology was first

introduced through an internet course, attracting huge interest, including most of the global Top 10 paint manufacturers

• Answered the needs for better color strength, jet-ness, transparency, stability as reached with the classical polymeric- dispersants

• Applying the HMV based products enables to reach highest quality performances and is used now in automotive, wood, industrial coatings as well as pigment concentrates

• Achieved approvals from MNCs

Technology used in: Pat-Add DA 932/ -934/ -603

HMV CONCEPT IN DISPERSION PROCESS

Wetting Grinding StabilizationPIGMENTS

Efficiency of the wetting • Surface tension properties of the pigment and the vehicle• The adsorption mechanism depends on the chemical nature of the pigment and the types of dispersing agents used.

Mechanical Shear• Higher surface areas become exposed to the vehicle and larger amounts of additives are required to wet out newly formed surfaces.

Stabilizing of Pigment dispersion• Electrostatic stabilization• Steric stabilization• Entropical Stabilization

ΔDa

Higher volume contributes to thicker adsorbed layer, preventing attractive

forces to dominate stabilizing forces: stable dispersion!

• Solvent OK for dispersant• High pigment concentration

Optimal adhesion conditions

• Strongly diluted pigment dispersion• Solvent too strong for dispersantDesorption dispersant, due to poor anchoring and desorption!

Consequence: poor performance, -strength, rub, low gloss, etc.

Classical problem: poor anchoring dispersant onto pigment Risk of de-sorption and loosing protection under adverse conditions, such as strong- diluted

dispersions, sharp solvents, innert pigments

• Solvent OK for dispersant• High pigment concentration

HMV Dispersant for Aqueous Pigment Concentrates

Summary

HMV Polymeric Dispersant, with Ultra Charge Functionality

• Higher Level of Dispersion, Robust stabilization benefitting in:

• For CBk- Darker Masstone- Bluer Undertone- Higher Jetness- Higher Gloss- Lower Viscosity

• High color strength for organic pigments

• Excellent transparency

• Optimal milling and stable dispersion

• Enabling high loaded pigment concentrate formulas
