Modification of Alkyd with Epoxy and its Application for Paint. Part 2: Durability of Paint Manufactured from this Ester
Main Article Content
Abstract
This article synthesized the epoxy alkyd ester resin by modifying alkyd resin with epoxy resin. The characteristics of synthesized resin was considered through the thermo-oxidation resistance, the chemical resistance (in 5 wt.% HCl, or in 5 wt.% NaCl solution), the UV-thermo-humidity complex stability (30 cycles, each cycle of 8 hours in UV irradiation at 60 °C and followed by 4 hours of humidity condensation at 50 °C), and the thermal shock resistance (7 cycles, each cycle of 10 minutes in refrigerated chamber at - 50 °C and 10 minutes in oven chamber at + 50 °C) The results showed that the thermo-oxidation resistance, the chemical resistance, and the UV-thermo-humiditycomplex stability of the ester epoxy alkyd paint film were higher than that of alkyd paint film, while the thermal shock ability was similar to that of the alkyd paint.
