Currently, epoxy paint is being widely used in the industry. Nanotechnology can create many small nanometer-sized materials with many applications, it has brought many outstanding properties to epoxy paints. The aim of this study is to investigate the effect of TiO₂ nanoparticles in epoxy paint formulation towards metal surface. We created a sample of two-component epoxy paint, part A is epoxy resin, anti-sedimentation, dispersant substance, foam breaking agent, cover substance, solvent, other additives, and part B is a curing agent for epoxy resins.  Methods of analyzing the properties of the epoxy paint film are based on Vietnam standards. TiO₂ nanoparticles are a good coating substance in epoxy paint. The study results showed that TiO₂ nanoparticles have increased the properties of the epoxy paint film, improving the Impact and Glossy of the epoxy paint film. TiO₂ nanoparticles increases from 1% to 6% by weight, the impact increased by about 18.75%.  (80 to 96 kg.cm), Glossy 60⁰ increased by about 12.79% (80 to 97). Adding TiO₂ nanoparticles to epoxy paint has increased Impact and Glossy for the paint film. The higher the rate of TiO₂ nanoparticles, the better the properties of the epoxy paint film. Therefore, TiO₂ nanoparticles are a good coating in epoxy paint, it improves the properties of the paint film. Because the cost of nanomaterials is higher than that of normal coating materials, the nanomaterial should only be added with a ratio of about 2-5% by weight.
