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.

“…Ove alkidne smole umrežavaju pod dejstvom svetlosti i kiseonika iz vazduha (oksidativno sušenje) [4,5]. Sam mehanizam umrežavanja uključuje otkidanje vodonika sa alilne metilenske grupe pri čemu nastaje slobodni radikal koji reaguje sa kiseonikom iz vazduha i nastaje hidroperoksid [6][7][8]. Razlaganjem tako nastalog hidroperoksida nastaju slobodni radikali koji dovode do umrežavanja alkidne smole.…”

IzvodSferne čestice TiO 2 različitih veličina dispergovane su u alkidnoj smoli. Površinska modifikacija nanočestica TiO 2 izvedena je propil galatom i lauril galatom. Ispitivan je uticaj veličine nanočestica TiO 2 , koncentracije, kao i vrste površinske modifikacije na reološka svojstva alkidne smole. Dobijeno je da je viskoznost pripremljenih disperzija veća od viskoznosti čiste smole, da raste sa smanjenjem prečnika čestica i opada sa povećanjem frekvencije. Površinski modifikovane čestice imaju veći uticaj na viskoznost alkidne smole nego nemodifikovane zbog povećanja efektivnog zapreminskog udela čestica u disperziji. Za najmanju koncentraciju TiO 2 viskoznost je veća kada je modifikacija izvršena lauril galatom, dok sa povećanjem koncentracije, zbog manje disperzione stabilnosti čestica modifikovanih propil galatom, dolazi do njihove aglomerizacije i naglog povećanja viskoznosti.

“…Moreover, the presence of resins in paints not only provides the resistance to water and abrasion effects but also helps to decrease the overall drying time. Alkyd resins could be produced from fatty acids and are most widely used in alcoholysis processes [3][4][5][6]. Pentaerythritol phthalic anhydride resin (PPR) is used as a binder in coating compositions, adhesive, plastics, varnishes, printing inks and floor coverings.…”

Alkyd resins, a type of polyesters obtained through esterification of a polybasic acid and polyhydric alcohol (e.g., pthalic anhydride and pentaerythritol). This study aimed to synthesize and characterize pentaerythritol phthalic anhydride resin by using soybean oil, pentaerythritol, phthalic anhydride and litharge (PbO) catalyst through alcoholysis method. FTIR and DS/TGA were used to characterize the freshly obtained pentaerythritol phthalic anhydride resin. Based on results, acid value 7.9 mgKOH/g is beneficial for the quality synthesis of pentaerythritol phthalic anhydride resin having high thermal stability even upto Tmax = 670 ºC.
