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 &lE;1.5.

Environmentally preferred fluids and fluid blends

The invention concerns fluids that have a low reactivity with respect to ozone formation, blends thereof, and the replacement of conventional industrial solvents with said fluid or fluid blends in order to reduce tropospheric ozone formation.

Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1.4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1.5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.
