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

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

Vinyl Acetate

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

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
