What coatings are used for internal anti-corrosion in benzene, toluene, and xylene storage tanks?

I have made tanks using these types of media, but I have not done any internal anti-corrosion treatment.

What materials are used for the storage tanks used to store benzene and xylene?

We use carbon steel tanks to store these materials, with no internal anti-corrosion treatment.

Carbon steel, with the material selected in accordance with the tank design standards.

Epoxy anti-static coatings are mainly composed of epoxy resin, conductive fillers, solvents, curing agents, and additives. Epoxy resin is a fundamental film-forming substance that possesses good adhesion, chemical resistance, and mechanical properties; it enables the paint to adhere firmly to the surface of the substrate, forming a continuous coating. Conductive fillers are key components for achieving antistatic effects; common examples include graphite, carbon black, and metal powders. These fillers create conductive paths within the coating, allowing static electricity to be dissipated promptly and preventing its accumulation. The role of solvents is to dissolve epoxy resin and other components, adjust the viscosity of the coating to facilitate application. Commonly used solvents include toluene, xylene, acetone, etc. Curing agents enable epoxy resins to undergo cross-linking reactions, resulting in a solid coating with a three-dimensional network structure. Different types of curing agents affect the curing time and performance of the coating. Although used in small quantities, additives have a significant impact on the properties of coatings; for example, defoamers can eliminate bubbles formed during mixing and application, ensuring the smoothness of the coating surface ； Leveling agents enable the paint to level out better after application, resulting in a uniform coating layer ； Plasticizers can improve the flexibility and elasticity of the coating, enabling it to adapt to the deformation of the substrate. Furthermore, pigments may also be added to improve the appearance and weather resistance of the coating.

Epoxy antistatic oil-resistant coatings cannot be used for the internal anti-corrosion protection of benzene, toluene, and xylene storage tanks, as they will dissolve; this not only damages the anti-corrosion coating but also contaminates the medium stored therein.
