“…Other studies, however, found that linseed oil films reached a maximum mass within several days of curing and then began losing mass [14,20]. This mass loss is the result of the formation of volatile products from oxidation reactions [35,36].…”

The quartz crystal microbalance (QCM) was used to measure the time-dependent mechanical properties of an alkyd resin throughout the transition from its application as a liquid to the formation of a solid film. Three different regions of curing were observed, corresponding to solvent evaporation; early stage curing, where the mass increases as oxygen is incorporated into the film; and long-term curing, where the mass decreases as volatile compounds are released. Mechanical property changes obtained at 15 MHz with the QCM were correlated with measurements at much lower frequencies utilizing traditional dynamic mechanical analysis. These mechanical property changes were in turn correlated to chemical changes tracked with Raman spectroscopy. From the temperature dependence of the curing process we obtain an effective activation energy of 4.1 kcal/mol.

High solid (HS) alkyd resins with low amount of volatile organic compounds (VOC) were developed as the result of new VOC solvent directive that limit the amount of VOC in decorative paints. Due to specific chemical structure of HS alkyd resins and possible deterioration of some applicative properties the optimal combination of driers is an important subject of research. In our present work we studied the influence of Fe bispidon (Fe drier) and Co ethylhexanoate (Co drier) surface driers with Sr carboxylate (Sr drier) through drier on the film formation of HS alkyd coatings. The kinetics of autoxidation was analysed using FT-IR spectroscopy. Further, applicative properties like drying time and film hardness were examined. In the end, electrochemical impedance spectroscopy (EIS) was used to evaluate the quality of cured HS alkyd coating films after exposure in the humidity chamber. It was established that the addition of the Sr drier to surface driers accelerates the autoxidation process. As higher amounts of the Sr drier were added, final drying times were reduced and film hardness increased. The lowest diffusivity of ions through cured HS alkyd coating films was observed for Co/Sr and Fe/Sr drier combination at 1:1 concentration ratio.

“…The quest is stimulated by European REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) legislation since they have been classified as “CMR2‐Reprotoxic” by the Cobalt REACH Consortium. Recently, several manganese, iron, and vanadium‐based driers, suitable for alkyd binders, have been described in literature and some of them are already commercially available. Nevertheless, most of the alternatives still suffer several disadvantages (i.e., low solubility in formulation, intense coloration).…”

Catalytic properties of benzoylferrocene, as a representative of cobalt‐free drier, was investigated on alkyd resin modified with soybean oil. Mechanical tests, performed on alkyd films, revealed promising activity at low metal concentrations. A detailed analysis of time resolved infrared spectra was used for in‐depth investigation of chemical curing in the films. The experiments, performed in transmission mode, enabled determination of kinetic parameters for the autoxidation process. Effects of film thickness were investigated using attenuated total reflectance technique. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46184.
