Özet

This study investigated the effect of the dilution ratio on film properties of acrylic-modified water-reducible alkyd resins. First, new four-component acrylic-modified alkyd resins based on 1,3-propanediol containing 40% of the equivalent amount of acrylic copolymer to alkyd resin were synthesized using the fatty acid method. The synthesized acrylic-modified alkyd resin was then dissolved in isopropyl alcohol (IPA) at various ratios and further diluted using distilled water at various ratios to obtain by-weight percentages of 70/50, 70/60, and 80/60 of solid content to IPA and water, respectively. Films of the modified alkyd resins were prepared, and cured at 150A degrees C for 1 h, then their physical and chemical surface coating properties and thermal behaviors were investigated. The best results were obtained for the by-weight percentages of 80/60.
