This study determined physical parameters by an atomic-increment approach and electronic descriptors using the Parametric Method 3 (PM3) semi-empirical method. Clear relationships were established between the effective molar cohesion energy and the solubility parameter with van der Waals volume. Linear dependencies were also obtained between the diluent surface tension and spreading coefficients on model high-hardness fillers, including silicon carbide, boron carbide, and normal corundum. The activity of epoxy diluents depends on the lowest unoccupied molecular orbital energy. These diluents influence processing and the final physical and mechanical properties of composites, making their selection critical for strength, hardness, and wear resistance. Computational analysis enables prediction of diluent behavior, reducing experimental time and cost. Integrating physical and quantum-chemical data into epoxy diluent design accelerates the search for optimal components and improves production of durable, high-performance epoxy composites.<\/jats:p>","DOI":"10.3390\/ma18245643","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T08:46:52Z","timestamp":1765874812000},"page":"5643","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Application of Physical and Quantum-Chemical Characteristics of Epoxy-Containing Diluents for Wear-Resistant Epoxy Compositions"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5783-3287","authenticated-orcid":false,"given":"Andrii","family":"Kulikov","sequence":"first","affiliation":[{"name":"Faculty of Manufacturing Technologies with the Seat in Presov, Technical University of Kosice, Bayerova 1, 08001 Presov, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kostyantyn","family":"Sukhyy","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8306-578X","authenticated-orcid":false,"given":"Oleksandr","family":"Yeromin","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0389-3073","authenticated-orcid":false,"given":"Marcel","family":"Fedak","sequence":"additional","affiliation":[{"name":"Faculty of Manufacturing Technologies with the Seat in Presov, Technical University of Kosice, Bayerova 1, 08001 Presov, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olena","family":"Prokopenko","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iryna","family":"Sukha","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5577-3869","authenticated-orcid":false,"given":"Oleksii","family":"Poloz","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oleh","family":"Mikats","sequence":"additional","affiliation":[{"name":"Department of Ecology, Heat Transfer and Labor Protection, Faculty of Mechanical Engineering and Environmental Protection, Ukrainian State University of Science and Technologies, 49000 Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5318-5772","authenticated-orcid":false,"given":"Tomas","family":"Hrebik","sequence":"additional","affiliation":[{"name":"Faculty of Manufacturing Technologies with the Seat in Presov, Technical University of Kosice, Bayerova 1, 08001 Presov, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2357-8975","authenticated-orcid":false,"given":"Olha","family":"Kulikova","sequence":"additional","affiliation":[{"name":"Faculty of Manufacturing Technologies with the Seat in Presov, Technical University of Kosice, Bayerova 1, 08001 Presov, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Lopusniak","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering, Institute of Architectural Engineering, Technical University of Kosice, Bayerova 1, 08001 Presov, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pascault, J.R., and Williams, J.J.
