Comparison of characteristics of two antibacterial agents in antibacterial powder coatings

The main components of antibacterial powder coatings and the principle use of antibacterial powder coatings. It is known that the antibacterial powder coating is a thermosetting powder coating composed of a resin, a curing agent, an antibacterial agent, a pigment, a filler and an auxiliary agent.

The antibacterial agents used in antibacterial powder coatings can be divided into two types: contact type and dissolved type. The inorganic antibacterial agent mainly composed of silver ions is a representative of a contact type antibacterial agent, and the general organic compound antibacterial agent is a dissolved type. Compared with the two antibacterial agents in the antibacterial powder coating, the contact type has better antibacterial effect than the solvent type, and has a wide range of suitable strains, is not easy to produce drug resistance, and has high safety, and the disadvantage is easy discoloration.

At the same time, the carrier of the inorganic antibacterial agent in the antibacterial powder coating is such that the spherical particles made of the porous zeolite or the inorganic ion exchanger are coated with the surface layer of the activated carbon, and the antibacterial metal is adsorbed on the carrier. In China, mobile phones, public telephones and other products have also begun to apply antibacterial powder coatings. In addition, antibacterial powder coatings are also used in the coating of merchandise display cases, medical facilities, beds, steel furniture, mobile phones, telephones, and the like.
