| Epoxy coatings are widely used due to their strong adhesion and mechanical performance, yet they often suffer from brittleness and limited durability. The effect of montmorillonite (MMT, NanoBent ZR2) on the mechanical and adhesion performance of epoxy coatings cured with polyamide (PAC) and amine (IDA) agents was systematically investigated. Unlike previous studies focusing solely on filler addition, this work examines the combined influence of curing agent chemistry and thermal conditioning. The incorporation of 3 wt% MMT increased tensile strength and bending strength of PAC-based coatings by up to 15 % and 20 %, respectively, after conditioning at 50 °C. In contrast, IDA-based systems showed limited improvement and higher brittleness. Conditioning temperature strongly affected performance: specimens cured at 50 °C exhibited more than 40 % higher tensile strength compared with those conditioned at 0 °C. PAC-based coatings also demonstrated superior adhesion (ASTM 5B rating) and cohesive failure modes, while IDA-based coatings frequently failed adhesively. These results highlight that optimizing both curing chemistry and nanofiller content yields epoxy coatings with enhanced mechanical strength and interfacial durability. |
