The article presents a study of the effect of multi-walled carbon nanotubes (MWNTs) on the pull-off strength value of epoxy resin floors, with a focus on the challenges posed in industrial facilities. The study consisted of modifying epoxy resin with three types of MWNTs in different amounts and evaluating their adhesion to substrates. The results showed that all achieved adhesion strengths exceeded the minimum required value of 1.5 MPa. The type and amount of MWNTs added influenced the adhesion strength of the epoxy resin. The highest average pull-off strength was achieved with 2.5% MWNT type II addition, it was 4.14 MPa. At 5% addition of MWNT type I, a drastic decrease in adhesion strength was observed, resting at 1.93 MPa. The article also discusses the challenges encountered during the mixing process, particularly with 5% type I MWNT addition. The methodology for testing and preparing the epoxy coating is also presented. The article brings a novel approach by analyzing the impact of different types and amounts of MWNTs on the pull-off strength of epoxy resin floors. The study demonstrated that the addition of MWNTs significantly enhances the pull-off strength, with optimal results obtained with a 2.5% addition of MWNTs type II, thus substantially expanding the current knowledge on the application of MWNTs in industrial flooring. In conclusion, the analyses carried out highlight the importance of considering the type and amount of MWNT to optimize the adhesion strength of modified epoxy resin floors. The study also contributes to the understanding of the potential applications and limitations of this type of composite in industrial flooring.
