Water-based zinc-rich primer for steel structure
Good anti-corrosion ability to meet the protection requirements of the entire coating;
Using water as the dispersion medium, no toxic and harmful substances are produced during the construction process and the coating film forming process, which meets the requirements of environmental protection; two-component curing, good hardness, good adhesion, and chemical resistance;
The compatibility is good, the coating film is firmly attached to the metal substrate, and the adhesion of the upper coating film can be enhanced.
It is suitable for anti-rust and anti-corrosion of heavy steel surfaces of various large-scale steel structures, ships, mechanical equipment, bridges, etc.
Remove oil, grease, etc. with a suitable cleaning agent. Sandblasted to Sa2.5 grade or SSPC-SP10 grade, the surface roughness is equivalent to Rugotest standard N0.3. Construction within 6 hours after sandblasting is the best solution.
It can be applied by roller, brush and spray. High pressure airless spray is recommended to obtain a uniform and good coating film.
Before construction, the AB component liquid material must be stirred evenly with an electric mixer, and then the AB component must be mixed evenly. Before construction, it is recommended to close the feed inlet with an 80-mesh filter. If the viscosity is too thick, it can be diluted with water to the construction viscosity. In order to ensure the quality of the paint film, we recommend that the dilution amount is 0%-10% of the original paint weight. The relative humidity is less than 85%, and the construction surface temperature is greater than 5°C and greater than the dew point temperature by 3°C. Rain, snow and weather cannot be used outdoors. If construction has already been carried out, the paint film can be protected by covering it with a tarpaulin.
