Alkyd paint is a very popular paint used in industry and life to protect the surface of steel, wood, and equipment against the harmful effects of the environment. The aim of this study is to assess the effect of BaSO4 nanoparticles on alkyd resin paint films to protect metals. The research method is selecting the traditional alkyd paint formula, then replacing this coating powder CaCO3 with BaSO4 nanoparticles to monitor the properties of the paint film over time. Methods of analyzing the properties of the paint film are based on Vietnam standards. The study results showed that CaCO3 coating powder replaced by BaSO4 nanoparticles had increased the properties of the paint film, improved the thickness, gloss, and durability of the paint film. BaSO4 nanoparticles increased from 1% to 6% by weight, the impact increased by about 11.29% (70 to 79 kg.cm), Glossy 600 increased by about 10.79%, Glossy 850 increased by about 10.92%, especially the durability of paint film over time increased nearly double. However, BaSO4 nanoparticles are more expensive than CaCO3, so they should replace less than 6% by weight to increase the quality of the paint film. This ratio is changed according to the actual equipment requirements.
