Effect of Modification with Various Epoxide Compounds on Mechanical, Thermal, and Coating Properties of Epoxy Resin

Abstract

Epoxy resin (ER) was modified with four different epoxide compounds, 4,5-epoxy-4-methyl-pentane-2-on (EMP), 3-phenyl-1,2epoxypropane (PhEP), 1-chloro-2,3-epoxy-5-(chloromethyl)-5-hexene (CEH), and a fatty acid glycidyl ester (FAGE), to improve its chemical and physical properties. The effects of the addition and amount of these modifiers on mechanical, thermal, and coating properties were investigated. Atomic force microscopy was used to observe the changes obtained with the modification. The influence of the modifying agents on the curing process was monitored through FTIR spectroscopy. The curing degrees of ER and modified ERs (M-ERs) were found to be over 91%. The results showed that tensile strength of ER improved till 30% (wt.) with addition of the modifier content. Modification with EMP and PhEP remarkably enhanced the thermal stability of ER to be highly resistant to the corrosive media.

Corrosion Resistance Synergistic Appraisal of Titanium-Impregnated Bisphenol A-Type Epoxy Duplex Coating System in Stimulated and Natural Marine Environments of Southeastern Coastal Area of China–Pakistan Economic Corridor

“…Results indicated that the drying time of the epoxy coatings was decreased with the addition of metal powder in the order T 0 > T 5 > T 10 . These results are in agreement with other researchers who had reported that the incorporation of the different metallic fillers on a micro-and a nanoscale had decreased the curing time of the coating [35][36][37]. PVC is an essential tool for coatings and is responsible for the gloss and hiding power.…”

“…Dry film thickness, % pigment volume concentration (PVC), % volume of Ti metal powder, drying time, pencil hardness, and adhesion loss of T 0 , T 5 , and T 10 coatings were measured. Earlier work has shown that drying comprises many time-consuming physical and chemical reactions, including polymerization, evaporation of the organic solvent, and oxidation reaction of the resin [34][35][36][37]. It is influenced by variables like light, temperature, nature of the substrate, the thickness of the film, and air movement [34,35].…”

Hygrothermal chamber aging effect on mechanical behavior and morphology of glass fiber-epoxy-nanoclay composites

“…Epoxy polymer resin has outstanding characteristics, such as extraordinary strength, limited shrinkage, & excellent heat and chemical resistance. Because of its unique properties, epoxy is used in many applications as coats, bonding agents, and matrix constituents for composites [1]. Cured epoxy systems have shown minute endurance to crack instigation and propagation & poor fracture toughness, in its applications [2].…”
