This research was financed in the framework of the project Lublin University of Technology, Regional
Excellence Initiative, funded by the Polish Ministry of Science and Higher Education, grant number 030/RID/2018/19.
This article presents the initial test results examining basic technological factors, such as
type of modifying agent and seasoning time, which influence properties of adhesive epoxide
compositions. The aim of the study was to prepare adhesive compositions with 2% content of the
selected natural fillers (montmorillonite NanoBent ZR‐2, ground chalk (powder)—CaCO3, and
activated carbon powder C) and to examine their strength properties. A polymeric matrix used to
prepare an adhesive composition consisted of the epoxide resins used in industry: Epidian 5 and
Epidian 53 cured by addition of an aminomethyl group, where curing occurred through the
Mannich reaction. A composition of epoxide resins with a curing agent and without any modifying
agents was used as reference. The examinations described in the present article aimed to show the
significance of the impact of the fillers used on the strength properties of the examined
compositions. A fracture surface of epoxide adhesive compositions modified with the selected fillers
was tested by means of a scanning electron microscope.
