Waterborne epoxy coating for steel structures
Product description
This product series is a new generation of environmentally friendly anti-corrosion coatings, prepared with water-based two-component epoxy resin, amine curing agent, mica iron oxide, nano-functional materials, other anti-rust pigments, corrosion inhibitors and additives, without adding organic solvents.
Product performance
Good anti-corrosion ability, good adaptability among primer, intermediate coat and top coat;
With water as the dispersion medium, no toxic and harmful substances are produced during the construction process and the coating film-forming process, which meets environmental protection requirements; two-component curing, good hardness, good adhesion, excellent chemical resistance; good aging resistance, not easy to be brittle; Good compatibility, the coating film is firmly attached to the metal substrate, and can enhance the thickness and fullness of the coating film.
Application range
It is suitable for all kinds of large indoor steel structures, especially for chemical workshops and other highly corrosive environments.
Surface treatment
Remove oil, grease, etc. with a suitable cleaning agent. This product must be applied on the base coat, and the substrate is free from oil and dust. If there is rust, it must be treated with primer before applying intermediate paint.
Construction instructions
It can be coated, brushed and sprayed. It is recommended to use high-pressure airless spraying to obtain a uniform and good coating film.
Ratio of main paint and curing agent: 1:0.1, the main paint must be stirred evenly before construction, and curing agent should be added according to the ratio. It is recommended to use an electric mixer to stir for 3 minutes. . If the viscosity is too thick, you can add clean water to dilute to the construction viscosity. In order to ensure the quality of the paint film, we recommend that the amount of water added be 5%-10% of the original paint weight. Multi-layer construction is adopted, and the last layer of coating must be carried out after the surface of the previous layer of paint is dry. The relative humidity is less than 85%, and the construction surface temperature is greater than 10°C and greater than the dew point temperature of 3°C. Rain, snow, and weather cannot be used outdoors. If it has been constructed, it can be covered with a tarpaulin to protect the paint film.
