* When the paint film is exposed to excessive outdoor time, zinc salt will be formed, which will adversely affect the adhesion of the heavy coating. Therefore, the surface of the paint film must be subjected to brushing, sand sweeping or high-pressure fresh water rinsing, and sufficient time can be maintained during recoating. Interlayer adhesion.
Tool cleaning
All tools must be cleaned with WJX inorganic zinc-rich thinner after use.
Safety
Use this product with care. Please refer to the MSDS of this product before starting work.
Please pay attention to the safety precautions on the packaging label before and during use. In addition, the safety regulations prescribed by the relevant national or local government should also be observed.
Personal protection includes, but is not limited to, lung, eye and skin protection. If swallowed or otherwise in contact with this product, seek medical attention immediately. Precautions must be taken to prevent fire, explosion and environmental protection.
Precautions The construction site should be protected from open flames. This product can only be used in a well ventilated condition. Strong ventilation is required in applications where it is confined or where air is not circulating.
Air humidity: When the ambient humidity is higher than 80%, construction is not recommended.
Ambient temperature: When the ambient temperature is continuously below 5 °C or above 45 °C, construction is not recommended.
Surface temperature of the substrate: The surface temperature of the steel must be higher than the dew point by 3 °C during construction; however, if the surface temperature is too high, the film defects will be caused. Therefore, when the surface temperature of the substrate is higher than 50 °C, the construction conditions should be adjusted and the construction at noon will be carried out. Move to morning and evening.
Other aspects: When painting, it is necessary to prevent the surrounding environment from causing pollution to the paint film, such as: sandblasting, paint fog lamps. Avoid construction in the case of rain, snow, fog, sandstorms, and stop construction in areas with strong winds or high pollution. Excessive ventilation will cause the coating to dry too quickly and the paintability of the coating will deteriorate, and a large amount of pollutants ( Such as sand, salt particles, corrosion deposits) will cause the film properties to deteriorate, and the loss will increase.
After the two components are mixed, they are filtered using an 80-100 mesh filter bag and used. Stir with a dispersing machine and continue to stir during use to prevent precipitation of zinc powder.
For best performance, the temperature of the film should be kept above 10 °C during film formation, and the humidity should be kept above 65%. If the humidity is lower than required, spray air into the air with air spray gun or other methods after the construction is completed. In order to increase the humidity, it is forbidden to directly spray water on the surface of the coating to avoid film defects.
Oil-based resin paints, alkyd resin paints and other alkali-resistant paints cannot be directly coated on inorganic zinc-rich primers. The zinc salt formed on the surface of the paint film must be completely removed when the coating time is long.
