This article presents the results of a study that showed that the addition of polyethylene polyimine to industrial silicone enamel KO-814 improves the dispersion of aluminum pigment and the quality of coatings. The study showed that the maximum effect is achieved with the content of 0.48% of the additive by weight of the pigment. The addition of polyethylene polyimine also improves the aggregate stability of enamel, which is manifested in a decrease in the deposition rate by 25% and a decrease in the average diameter of pigment particles by 85% compared to enamel without an additive. The obtained optimal concentration of polyethylene polyimine (0.48% of the additive in silicone enamel) leads to a 3.5-fold decrease in the corrosion rate of the steel base and a 43-52% decrease in the water absorption of coatings. These results can be useful in the production of industrial coatings, such as automotive paints, metal structures and other products where high quality coatings are required. The use of polyethylene polyimine can improve the properties of coatings and increase their durability.
