BRIEF HISTORY OF VAE() DISPERSION & CURRENT

EUROPEAN DISPERSION MARKET

BINDER EVOLUTION DRIVEN BY TECHNICAL & ENVIRONMENTAL

MARKET DEMAND

1950 1960 1970 1980 1990 2000 2010

• Development of cellulose

stabilized dispersions

• First Acrylate system

introduced

• Launch first terpolymers

• Fundamental work with

Ethylene as “softening” agent

• Strong pressure to develop

more environmentally friendly

binders in Europe

• VAE(*)-dispersions gaining

widespread attention in

coatings in US

• US: VAc-A Copolymers

introduced

• EU: launch of plasticized

PVAc dispersions

• Optimization of VAc-E and

VAc-E-VC copolymer emulsion

copolymerization for EU paints

and coatings

VAE() TECHNOLOGY GAINING MARKET SHARE OVER TIME

• European Dispersion Market for Coatings: about 1 million ton of dispersion in 2009

• VAE() proportion growing since 20 years: from 10% in 1996 to 14% in 2009

• Further development of the VAE() technology seen

• VAE at 20+ % market share in short term future is a realistic assumption

• Environmentally friendly wave (growing awareness of consumer, always more restricting

legislation, eco-labels, …) supporting this evolution

WHY ARE SOLVENTS & VOC A CONCERN?

• Combination of

• UV coming from sun activity

• NOx produced by combustion

• Solvents from various chemicals

lead to formation of summer smog (ozone

building up in troposphere)

• Ozone very harmful to humans

• e.g. allergy, asthma, heart attacks and

other cardio-pulmonary issues

• Program to decrease amount of solvent in deco paints initiated long time ago across the world

WHY ARE SOLVENTS & VOC A CONCERN?

• Today more than 80% of total architectural paint production is water based

• Strong regional differences regarding ration water-based & solvent-based

• Strong regional differences regarding level of VOC / solvent used in formulation

• Different understanding about definition of solvent

• Global trend toward less solvent & VOC however undisputable

Tareq Awadallah,


INDOOR AIR QUALITY …: NOT NEUTRAL FOR HUMAN HEALTH

• Indoor smoke containing many

dangerous pollutants produced by

heating / cooking / cleaning

activities

• High & efficient insulation system

prevents from good aeration /

ventilation leading to accumulation

of these pollutants in the house

• Most heaviest pollutants accumulate

on surfaces due to migration of

solvent & plasticizer, creating

“fogging” effect

Most important sources of organic indoor pollutants

•Outdoor environment

•Man & his activities

•Materials Equipments (adhesives, caulks, floor covering,

sealants, furniture, paints, wall covering, particle board, ….)

WACKER VINNAPAS® VAE() DISPERSIONS …. A PART OF

THE SOLUTION?

A LITTLE BIT OF CHEMISTRY

STRUCTURE OF A VAE() POLYMER DISPERSION

• Vinyl Acetate Monomer (VAM)

• Based on Carbon, Hydrogen & Oxygen • Hard (Tg ~ 32°C) • Hydrophilic Character • Toughness

• Ethylene (E)

• Based on Carbon & Hydrogen • Very soft (Tg ~ -125°C) • Hydrophobic Character • Flexibility • High hydrolysis resistance

• The ideal couple: Vinyl Acetate & Ethylene

Copolymer • Good compatibility • Good reactivity • Good stability • No major toxic by-products

Ethylene

Vinyl Acetate

Tareq Awadallah,


A LITTLE BIT OF CHEMISTRY

TWO MAIN PROPERTIES OF VAE COPOLYMER DISPERSIONS

• Tg

• Glass Transition Temperature

• Characteristic of the solid polymer

• Temperature at which polymer from a

glassy / vitreous state turn into a

rubbery / plastic state (E.g chewing

gum)

• The higher the Tg

• The higher the mechanical

performance (E.g. tensile strength,

cohesiveness, scrub, clean-ability)

• The higher the blocking resistance

• The lower the dirt pick-up

• MFT = MFFT

• Minimum Film Forming Temperature,

• Characteristic of the liquid dispersion

• Temperature at which the dispersion is

able to form a cohesive & consistent

film

• The lower the MFT is

• the better the film formation

• the least solvent or film forming agent

needed

• hence the lowest the VOC

Tareq Awadallah,


OUR DAILY ANTONYMIC CHALLENGE

DEVELOP BINDER WITH LOWEST MFT AND HIGHEST Tg

• WACKER R&D teams developed over years

knowledge, competencies & extensive

experience to bridge this critical but essential

gap.

• WACKER VINNAPAS® VAE()

dispersions

display significantly higher Tg than Acrylic or

Styrene Acrylic binder technology at low

MFT …

• …. therefore better performance in low VOC

paint formulations can be achieved with

WACKER VINNAPAS® VAE()

dispersions
