Water-based steel structure heavy-duty anti-corrosion topcoat series
Matching performance
Excellent 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;
Two-component curing, good hardness, good adhesion, chemical resistance, durability of more than 10 years. Good gloss and color retention.
Application range
It is suitable for various extra-large steel structures, ships, mechanical equipment, bridges, airports, oil tanks, oil pipelines and installations with harsh environments and high anti-corrosion performance requirements.
Surface treatment
This product series must be applied on the primer or intermediate coating, and the substrate is free of oil and dust. If there is rust, it needs to be treated with primer before applying topcoat.
Construction Description
High pressure airless spraying is recommended to obtain a uniform and good film.
Mix evenly according to the proportion. 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%-5% of the original paint weight.
The relative humidity is less than 85%, and the construction surface temperature is greater than 10°C and greater than the dew point temperature by 3°C.
