Analysis of the Influence of Basalt Powders on the Mechanical Properties of Epoxy Coatings

Epoxy resins are a popular material for floor coatings, especially industrial floors. Due to the harmfulness of epoxy resin, efforts are made to reduce the amount of epoxy resin needed to make the coating. Fillers and additives, especially mineral ones, are used for this purpose. The paper investigated the possibility of using three basalt powders as an additive to epoxy coatings. The weight content of basalt powders in the coating ranged from 0 to 29%. Two tests of the mechanical properties of the epoxy coating were performed. The hardness was tested with a Shore D durometer, and the pull-off strength was tested by the method of pull-off using an automatic device. It has been shown that basalt powders improve the hardness of the epoxy coating (by 8%) and do not deteriorate the pull-ff strength of the epoxy coating.
