Composition of anticorrosive coatings
Coatings are usually composed of film-forming materials, pigments and fillers, diluents and additives.
(1) film forming material
Film forming materials are usually composed of resins or oils. Its function is to make the coating form a continuous film firmly attached to the coated object, which is the basic material of the coating. The basic physical and chemical properties of the film mainly depend on the film-forming materials and coatings.
(2) Pigments and fillers
Pigments and fillers, together with the main film-forming materials, form the coating, which is mainly used to color and improve the performance of the coating, enhance the ability of protection, decoration and rust prevention of the coating, and reduce the cost of the coating.
(3) Diluents and additives
Diluents can be divided into ordinary diluents and active diluents. The active diluent is directly involved in the coating film formation and becomes a part of the coating. Ordinary diluent will not form a coating, but it also plays an important role in the coating film-forming process. It is indispensable in the coating composition. Diluent can adjust the viscosity of the coating to adapt to different coating construction, increase the storage stability of the coating, and improve the workability
Yes. In addition, in order to adjust the performance of the coating, various additives are added to the coating, such as drying agent, leveling agent, plasticizer, anti scaling agent, thixotropic agent, etc.
