Special Issue Information

Dear Colleagues,

Epoxy adhesives have properties superior to those of most other adhesive materials due to their excellent adhesion and chemical resistance. Wide varieties of resins and curing agents, together with their excellent capability to be modified (both chemical and physical), allow epoxy adhesives/materials to be adjusted for particular applications and conditions of use. This modification of epoxy materials enables the control of specific properties, such as shear and tensile strengths, tensile modulus, flexibility, and heat resistance.

This Special Issue focuses on types of epoxy adhesives/materials, epoxy resins, curing agents and other various types of additives and fillers, as well as their properties and the resistance of epoxy adhesives in different applications and environments. Epoxy materials are considered in terms of their characteristics, methods of modification, curing, testing and their applications.

Potential topics include, but are not limited to, the following:

  • Epoxy resins and curing agents;
  • Novel technologies and methods for modification of epoxy adhesives;
  • Structure, properties and applications of epoxy adhesive modifies and fillers; 
  • Mechanical, chemical and thermal properties of epoxy materials;
  • Resistance of epoxy adhesives and adhesive joints in various environments;
  • Advanced applications of epoxy adhesives;
  • Biobased epoxy adhesives and materials;
  • Sustainable epoxy resins from renewable resources.

This study aimed to evaluate the bondability of beech and alder wood modified through styrene polymerization within the wood lumen. Unmodified wood samples served as the reference material. Bondability was tested using four adhesive types commonly used in wood technology: polyvinyl acetate (PVAc), urea-formaldehyde (UF), phenol-resorcinol-formaldehyde (PRF), and epoxy resin. In addition to shear strength measurements, the adhesive density profile was also assessed. Results indicated that styrene modification generally reduced wood bondability, with reductions in shear strength ranging from 8% to 23% for beech wood and 1.6% to 29% for alder wood, depending on the adhesive type. The only exception was observed with the epoxy adhesive, which showed a 13% improvement in bonding quality for modified wood. These findings suggest that while styrene modification may enhance specific properties of wood, it can adversely affect its adhesion performance with some adhesive systems, except epoxy, which displayed improved compatibility with styrene-modified wood. The study offers insights for selecting suitable adhesives when using modified wood in structural applications. Full article

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).
