product manual
Low VOC, high solids two-component epoxy anticorrosive paint composed of epoxy resin, polyamide resin curing agent, micaceous iron oxide, anti-rust pigment, auxiliary agent and solvent.
The product has good rust resistance, wear resistance and durability, and has good corrosion resistance in industrial and chemical atmospheres. It has good matching performance with various top coats such as chlorinated rubber and polyurethane, and can also be matched with traditional paints such as alkyd and phenolic. It has excellent adhesion and sealing performance on substrates such as sandblasted steel and zinc-rich primer.
Product Usage
New and repaired steel construction surfaces for medium to harsh industrial corrosive environments can be used as a primer or intermediate paint. It can be used as an intermediate coating for high performance anti-corrosive paints such as epoxy zinc-rich primers and inorganic zinc primers to enhance the interlayer adhesion and protection properties of the entire coating.

* When the paint film is exposed to excessive exposure for a long time, it will be pulverized, 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 HY epoxy thinner
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 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 temperature is between -5 and 15℃, it is recommended to use winter-type products. The temperature is higher than 15℃ and lower than 45℃. It is recommended to use ordinary products, below -5℃ or above 45℃. 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.
