Dispersing Agents

27 April 2012 Slide 10 / 31

Surfactants:

– Ionic (amphoteric, cationic and anionic)

– Nonionic

Polymeric dispersants:

– High molecular weight dispersants

– Low molecular weight dispersants

The combination of surfactant and polymers

improve the desired properties of the

product.


Surfactant Dispersing Agents

27 April 2012 Slide 11 / 31

■ Advantages

– Traditional and economical

– Colour development

– Flow and levelling

– Compatibility with water and solvent based

formulations

■ Examples:

– Fatty acid derivatives

– Alcohol ethoxylates

– Phosphate esters


Polymeric Dispersing Agents

27 April 2012 Slide 12 / 31

■ Advantages

– New technology

– Enhance pigment wetting

– Lower viscosity pastes

– Increased dispersant efficiency – Cost in use

– Increased pigment loading

■ Examples:

– Polyisobutylene

– Polyesters

– Polymethyl methacrylate

– Polyethylene oxides

– Sodium polyacrylates / polyacrylic acid


Dispersing Agents Role

27 April 2012 Slide 13 / 31

■ Enhance the dispersion process

– Lowering viscosity of mill base

– Making dispersing time shorter

■ Ensure a fine particle size in order to stabilize pigments in the

resin solution

– Controlling settling (sedimentation)

– Improving colour development and gloss

– Tone purity by the high saturation value

– High covering

■ Perform the three main functions: pigment wetting, dispersing,

and stabilizing

– Preventing pigment flocculation


Dispersion Stabilization Mechanisms

27 April 2012 Slide 14 / 31

■ Electrostatic Stabilization ■ Steric Stabilization


Dispersing Agents Choice

27 April 2012 Slide 15 / 31

■ Dispersing agents choice:

– Cost target

– Final application: coating system (water based, solvent based, etc.)

– Dispersing agents generally differ for aqueous and solvent-based coatings

■ Ecological compliance:

– Solvent-free

– APEO-free

– Very low trace amounts of heavy metals are contained

– Environmentally friendly product certificates

Performance Evaluation Water Based Paints

Pigment Preparation:

– Weighting the water

– Addition of wetting agent, Polyglycol G 200.

– Addition of the dispersing agent

– Addition of biocide and defoamer.

– Homogenization

– Grinding with a dissolver

– Pigment addition in small fractions until total

incorporation of the pigment

– Evaluation of the viscosity and the tinting

strength in water based paints

27 April 2012 Slide 18 / 31

■ Application in water based paints:

– 6% w/w of pigment preparation in a

white WB paint (European Standard)

– Homogenization

– 200 µm film draw down

– After drying 24h at room temperature,

the determination of the tinting strength

was carried out using a

spectrophotometer.

Compatibility evaluation with alkyd enamel:

– Addition 6% w/w of pigment preparation in an alkyd enamel,

which is composed of 98.5% base and 1.5% drying agent.

– 200 µm film draw down

– Rubout evaluation

– After drying 24h at room temperature, the determination of the

tinting strength was carried out using a spectrophotometer

Pigment Preparation:

– Weighting the water

– Addition of wetting agent, Polyglycol G 200.

– Addition of the dispersing agent

– Addition of biocide and defoamer

– Homogenization

Conclusion

■ Dispersogen PTS:

– Low VOC

– Economic for organic pigment dispersion

– Use of 6% a.i. generates stable preparation for a wide range

of pigments

– For some pigments is also possible lower concentrations

Dispersogen ECS:

– Highest tinting strength for SB paints

– Compatible with water based, solvents and alkyd enamel

– Specially indicated for universal colorants

Dispersogen PL30 and PL40:

– Low viscosity preparations for water based applications

– Allows high pigment load

– High tinting strength

Products for

Construction

Plasticizers

Plasticizers and Superplasticizers are additives that make possible to obtain fluid

concretes and water reduction.

27 April 2012 Slide 24 / 31

Modern construction process requires:

• Auto-compactation properties for self compacting concretes

• High flowable concrete

• High durability for high performance concretes


Water / Cement ratio (W/C)

The increase of W/C ratio results in:

The decrease of W/C results in:
