A primer containing a large amount of zinc powder is called a zinc-rich primer. Zinc-rich primer with its excellent anti-corrosion performance in petroleum and petrochemical, road bridges, coastal facilities, offshore platforms, ships, steel beam steel and other heavy anti-corrosion areas already show their strong advantage. Water-based zinc-rich paint and give it a healthy ecological, safe operation of the environmental characteristics, to its advantage a higher level. At present, all human beings are calling for the protection of ecology, energy saving and emission reduction, the development of environmentally friendly coatings is the general trend of the current coatings industry. The water-based zinc-rich paint applied to the field of heavy-duty, its broad prospects are self-evident.
Water-based zinc-rich scale cathodic protection primer is 600-1500 purpose zinc flake as a rust paint. Flake zinc powder is a low oil absorption, low water absorption of high-shielding filler, multi-layer parallel to the matrix and the substrate arrangement, the medium diffusion of the curve becomes curved to extend the diffusion of the media to the matrix diffusion path, acid and alkali , Resistance to salt spray performance can be strengthened, the film tough, with good adhesion, flexibility, wear resistance and sealing performance, anti-corrosion function than the spherical zinc-rich zinc paint a step closer. It does not require thicker film, only 15-20μm dry film thickness can achieve a strong anti-corrosion effect. For reducing the corrosion resistance of the coating substrate to reduce the number of coating Road, thereby saving manpower and resources, reduce corrosion costs, should be a very good cost-effective products.
