Abstract

In this study, a high molecular weight epoxy resin (ELM-NG 900Z) based on diglycidyl ether of bisphenol A was cured with different types of hardeners to examine their impact on the physical and mechanical properties of the epoxy resin. The hardeners used were G-5022X70 (140-170 mg KOH/g), G-A0533 (310-350 mg KOH/g), and G-0930 (280-320 mg KOH/g). The results indicated that the hardener G-A0533 provided the best mechanical properties for the epoxy resin compared to other hardeners. Furthermore, various additives including silica fume, talc, barium sulfate, ferric oxide, and pigments were mixed with the epoxy resin in the presence of the hardener G-A0533 to enhance its mechanical properties. It was observed that the addition of 3% silica fume, 10% ferric oxide, and 3% inorganic pigments improved the mechanical properties, while the addition of 5% talc decreased most mechanical properties and only increased hardness. The incorporation of barium sulfate into the epoxy resin enhanced adhesion and flexural strength but decreased tensile strength and hardness. The inclusion of organic pigment had no significant effect on the mechanical properties of the epoxy resin. This enhancement in mechanical properties is attributed to the type of hardener used as well as the types and amounts of additives mixed with the epoxy resin.
