Radioactive Waste Container Coatings Available

Beijing University of Chemical Technology and Beijing Nuclear Engineering Research and Design Institute recently developed a coating for radioactive solid waste steel packaging containers.
This product is a two-component epoxy resin coating. Its base material is bisphenol A epoxy resin. It not only has excellent adhesion to steel containers and chemical resistance (especially alkali resistance), but also has good thermal stability. , And excellent radiation resistance, easy removal of radioactive waste. The curing agent for the coating is a modified aromatic amine, which not only has advantages of low toxicity, low viscosity, good compatibility, moderate curing speed, etc., but also has antiradiation and heat resistance of the coating due to its aromatic ring structure. improve. In addition, the solvent of the coating is xylene and butanol; the pigment is graphite with good radiation resistance; the filler is talcum powder, and also contains an appropriate amount of dispersant, toughening agent, anti-aging agent and the like.
