Waterborne antirust primer directly on rusty surfaces

Product description

This product is a new generation of environmentally friendly rust-resistant anti-rust paint. It adopts the latest steel anti-corrosion technology to provide long-term and efficient protection for rusted steel surfaces without pretreatment. It not only significantly prolongs the service life of the anti-corrosion finish paint, but also The anti-corrosion coating process is simpler, more efficient, economical and environmentally friendly.

 

Product performance

The operation is simple and labor-saving, and the surface treatment requirements are less than other steel anti-corrosion coating technologies. There is no need for grinding, washing, pickling, sandblasting, phosphating and other treatments on the rust, and the anti-corrosion coating becomes very simple;

With water as the dispersion medium, no toxic and harmful substances are produced during the construction process and the coating film formation process, which meets environmental protection requirements; good adhesion, good matching, the coating film and the metal substrate are firmly attached, and the adhesion of the upper coating film can be enhanced.

 

Application range

It is mainly used for the protection of the steel structure surface that cannot be effectively shot blasted, sand blasted, and polished. The coating film can form a black paint film on the unpretreated steel surface to effectively seal the substrate; except for the surface of the company In addition to supporting paint, it can also be used as a matching primer for various solvent-based anti-corrosion coatings and other industrial paints for metal bases.

 

Construction instructions

Surface treatment: Use a wire brush to remove loose soil and rust accumulated on the metal surface. If there is oil on the base material, remove the oil first; Construction conditions: Construction should be carried out according to the best construction conditions normally required, construction and drying in a narrow space Provide plenty of ventilation during this time. It can be rolled, brushed and sprayed. Brushing can make the paint film penetrate into the steel gap more easily. It must be stirred evenly before construction. If the viscosity is too high, 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 0%-10% of the original paint weight. The relative humidity is less than 85%, and the construction surface temperature is greater than 0°C and greater than the dew point temperature by 3°C. Rain, snow, and weather cannot be used outdoors. If construction has already been done, methods such as covering with tarpaulins can be used to protect the paint film.
