Shandong Qingdao epoxy zinc-rich anti-rust primer steel anti-rust paint

Shandong Qingdao epoxy zinc-rich anti-rust primer epoxy zinc-rich anti-rust primer Introduction
Epoxy zinc-rich anti-rust primer is the zinc-containing anti-corrosion and anti-rust primer variety produced by Budweiser Paint. This paint is developed for steel structure substrates that cannot be sandblasted and rust-removed and require a zinc-rich primer. It has excellent adhesion and anti-rust properties.

Construction process of epoxy zinc-rich anti-rust primer
Construction conditions
The temperature of the substrate should not be lower than ℃, and at least higher than the air dew point temperature. The temperature and relative humidity should be measured near the substrate. . Good ventilation is usually required to ensure the paint dries properly.
Construction method
Spray airless spray or air spray. High pressure airless spraying is recommended. When using air spraying, attention should be paid to adjusting the paint viscosity and air pressure. The diluent should not be exceeded, otherwise it will affect the coating performance.
Brush coating is recommended for pre-coating and small area painting, but the specified dry film thickness must be achieved.

Anti-corrosion and anti-corrosion of epoxy zinc-rich paint Rust effect
The anti-corrosion and anti-rust effects of zinc-rich paint are mainly reflected in cathodic protection and self-healing.
The cathodic protection effect of zinc-rich primer
The cathodic protection effect of zinc-rich primer is achieved by sacrificial anodes.
Zinc-rich primer contains ultra-fine highly active zinc powder as an anti-rust pigment. This paint is different from other inert anti-corrosion coatings that only provide a fatigue effect. When zinc powder encounters moisture, it will evaporate before steel and air. Medium tidal response.
The repair effect of zinc-rich primer
In areas where the paint film is damaged, the zinc powder of the zinc-rich primer reacts electrochemically with moisture to produce zinc oxide, which is deposited on the damaged steel structure Surface, forming an inert protective coating. This self-repairing effect is especially significant with new paint films.
Due to its anti-corrosion and anti-rust effects in the above two aspects, zinc-rich primer has excellent resistance to salt spray and moisture and heat. It is widely used as a long-lasting anti-rust primer for steel structures in highly corrosive environments.
