* When the paint film is exposed for a long time outdoors or the surface is smooth, it has a bad influence on 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 can be cleaned with clean water 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
The construction site shall be protected from open flames and may only be constructed 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 relative humidity of the air is greater than 80%, construction is not recommended.
Ambient temperature: When the ambient temperature is below 5℃ or above 40℃, construction is not recommended.
Surface temperature of the substrate: The surface temperature of the steel must be higher than the dew point by 3℃ 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℃, 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.
