An industrial formulation-fluid system comprising one or more organic volatile formulation-fluids including a fluid F being a compound containing either an oxygen-containing or nitrogen containing functional group and being substantially free from unsaturated carbon-carbon bonds or aromatic groups. Fluid F is selected from the group consisting of: carbonates, acetates, dioxalanes, pivalates, isobutyrates, pentanoates, propionates, hexanoates, nonanoates, nitriles and mixtures of any two or more thereof, such that fluid F exhibits a reduction in ozone formation in an amount of at least 10 % less than that of the formulation-fluid system without fluid F. Also, fluid F has an ozone formation potential (OFP)(in accordance with the Absolute MIR scale in units of g. ozone/g. fluid F) of <= of 1.5.

L'invention concerne un système de fluide de formulation industriel qui renferme un ou plusieurs fluides de formulation volatiles organiques comprenant un fluide F étant un composé contenant soit un groupe fonctionnel à teneur en oxygène ou en azote et sensiblement exempt de liaisons non saturées carbone-carbone ou de groupes aromatiques. Le fluide F est sélectionné dans le groupe constitué par des carbonates, des acétates, des dioxalanes, des pivalates, des isobutyrates, des pentanoates, des propionates, des hexanoates, des nonanoates, des nitriles et des mélanges d'au moins deux des éléments précités, de façon que le fluide F présente une réduction de formation d'ozone d'une quantité au moins 10% inférieure à celle du présent système sans fluide F. Le fluide F possède en outre un potentiel de formation d'ozone (OFP) (conformément à l'échelle absolue MIR réactivités additionnelles maximales- en unités de g. d'ozone/g. de fluide F) <= 1,5.
