“…In this study, low-temperature curing agents were used to cure the epoxy resin, which allowed for us to conduct the curing process at room temperature. The advantages of the curing process conducted at room temperature have been presented in studies by Ellis [6], Ignateko et al [29], Hong and Tsai [54], Qaderi et al [55], and Grillet et al [27]. One of the advantages is that the epoxy resins cured in this way are suitable for many applications [6].…”

The objective of this study was to compare the selected mechanical properties of epoxy compounds based on an unmodified epoxy resin with those containing an antiseptic as a modifying agent. Experiments were carried out on twelve epoxy compounds made of an epoxy resin based on bisphenol A (BPA) with a basic epoxide amount of 0.48–0.51 mol/100 g. Three curing agents were used: one polyamide (a polyaminoamide curing agent) and two amines (one was an adduct of aliphatic amine and aromatic glycidyl ether, and the other was an adduct of cycloaliphatic amine). The epoxy compounds were modified by adding an antiseptic in the form of powdered boric acid (H3BO3) in three amounts: 0.5 g, 1.0 g, and 1.5 g. The cured modified and unmodified epoxy compounds were subjected to compressive strength testing and microscopic examination. The experimental results showed that the epoxy compounds containing adduct of aliphatic amine (triethylenetetramine) and aromatic glycidyl ether as the amine curing agent, i.e., E5/ET/100:18, had the highest compressive strength out of all the tested epoxy compounds, with the highest value of 119 MPa obtained for the epoxy compound modified by the addition of 1.0 g boric acid. The epoxy compounds modified with boric acid acquired antiseptic properties and, for most cases, exhibited a higher compressive strength than the unmodified epoxy compounds (not lower than that specified by the manufacturer for unmodified epoxy compounds).

“…This hardening reaction results in the formation of a three dimensional(rectangular) structure. There are various kinds of hardener available commercially, including diethylenetriamine type hardeners which are cured at room temperature (298 K), diethyl amino propylamine type hardeners which are cured at middle temperatures (298-313 K) and phthalic acid anhydride type hardeners which are cured at high temperature (>313 K), as well as acid anhydride and amine type hardeners [13][14][15][16][17][18][19][20][21][22][23]. In addition, some of the fillers used to improve the physical properties of the epoxy resin are listed in Table 2 [7].…”
