Hi Graham - I know I am just a materials engineer and at best, a dangerous

chemist but isn't "Hydrogen Di-Oxide " equal to HO2?

As you are in the UK, you need to know that there is no such thing as

VOC free materials in Europe because we (EU) do not differentiate

materials. They are either VOC or they not.



As defined by “Council Directive 1999/13/EC of 11th March 1999:



Organic compound shall mean any compound containing Carbon and at

least one or more of hydrogen, halogens, oxygen, sulphur,

phosphorous, silicon or nitrogen.



9. …emission shall mean any discharge of volatile organic compounds

from an installation into the environment. …into air, soil and water

as well as solvents contained in any products. They include

uncaptured emissions released to the outside environment via windows,

doors, vents and similar openings.



17. volatile organic compound (VOC) shall mean any organic compound

having at 293.15 K a vapour pressure of 0.01kPa or more, or having  a

corresponding volatility under the particular conditions of use.



In the USA, the EPA have given a list of tax exempt VOC's that permit

folks to market "VOC Free" products. Kinda wrong ain't it?



It is fair to say that some materials are worse than others but, a

VOC is a VOC. Don't forget Hydrogen Di-Oxide can kill you.



Kindest regards,



Graham Naisbitt
