This scientific analysis is dedicated to one of the most pressing issues in the automotive industry: reducing energy consumption in paint shops. Traditional convection curing ovens account for up to 70% of a car factoryʼs total energy consumption, which increases production costs and negatively impacts the environment. As an innovative solution to this problem, the technology of curing epoxy primers modified with basalt fiber using near-infrared (NIR) radiation is proposed. The research methodology is based on a systematic analysis of literature in the fields of materials science (properties of basalt fiber), polymer chemistry (primer composition, interfacial modification), process engineering (physics of NIR radiation, dispersion methods), and industrial engineering (energy efficiency). The main findings indicate that the synergy between the unique photothermal properties of basalt fiber and the ability of the epoxy matrix to absorb NIR radiation significantly accelerates the curing process and reduces energy consumption by up to 90%.
