Issues for Solvent and Water Based Coat ing s how tobecome GREEN ?

Source: SpecialChem - Jun 1, 2009

SED: Solvent Emission Directive

- Directive 99/13/EC in force from 31-10-2005

- Emission control tightened from 31-10-2007

- Directive 2004/42/CE in force from 01-01-2007

NEC: National Emission Ceiling

- National Emission Ceiling fixed from 2010- NECs tightened up to 2020

CAFE: Clean Air For Europe

- Clean Air For Europe - thematic strategy due July2005

- EC data (IIASA Report) suggests large reduction

beyond SED

World wide regulations have the potential to reduce

VOC by about 4 Mt/a *

INDUSTRY TARGETS

GOVERNMENT LEGISLATION


6/44

Water bo rne coat ing s are GREEN bu t they have somelimitations

not resistant against moisture

not stable against chemical attack

not blocking resistant

difficult to process

hard to dry

generally of lower quality than solvent borne alternatives

A lot of these arguments are based on preconception, but there

is also some truth

Thus, there is a continous need to improve the performance ofwaterborne coatings


7/44

Some principals to understand:

- A true nano system in any specific application may not

relate to primary particle size!

- Selection of the correct nano particle or carrier

- Stable system

- Compatible system

- Targeted functionality

How can Nanotechnology help with these issues ??

can result in interactions with the substrate causing adegradation of the substrate, loss of color & no UV
