Modification of safflower oil with triallyletheracrylate dienophile

Abstract

Alkyd resins and reactive diluents which are among the main components of dye and coating industries, have properties such as binding and easy application. In order to improve the film properties of alkyd resins, a wide variety of modification studies are carried out. In this study, safflower oil was modified with triallyletheracrylate dienophile (TAEA) with Diels - Alder reactions and the product was called as reactive diluent (triallyletheracrylate safflower oil). TAEASO reactive diluent have been characterized by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FT-IR) methods. Then, the different dye formulations were prepared with a certain proportions of reactive diluent, wetting and drying agents and a soy oil (SO) based alkyd resin. Dye formulations were called as SO, TAEASO10-SO, TAEASO20-SO, TAEASO30-SO, TAEASO40-SO. The viscosity reductions of the dye formulations were determined, and then the dye formulations were applied to surface of Aliminium plates as film and the film properties such as drying time, film thickness, pencil hardness, brightness were evaluated after the curing process. The results show that the viscosity reduction is proportional to the ratio of the reactive diluent. As a result of the study, the drying time for the reactive diluents with alkyds were 1.5 times faster than alkyd alone.
