Rear supporting paint
Can be compatible with coatings such as chlorinated rubber, epoxy, epoxy asphalt, asphalt, polyurethane, ethylene, etc
Use it* But it cannot be used in conjunction with oil-based, alkyd, or polyester paints.
matters needing attention
During the construction period, a mixer should be used to continuously mix to prevent the precipitation of zinc powder
When construction is carried out at temperatures above 30 ℃, it is necessary to add 0-10% of 107 diluent to prevent dry spraying
When the dry film thickness is lower than the requirement and a new coat of 704 inorganic zinc primer is needed, the 704 should be diluted with 50% 107 diluent before recoating to increase the interlayer adhesion of the paint film
To prevent pinhole corrosion and the formation of bubbles in the next coat of paint, H53-42 epoxy sealant or 842 epoxy mica iron anti rust paint diluted with 30-50% 103 diluent must be used to seal the 704 inorganic zinc primer
Before applying the next coat of paint, the paint film of 704 inorganic zinc primer must be completely cured, otherwise it will affect the interlayer adhesion. Before painting, use a cloth or yarn dipped in 107 diluent to wipe the paint film. If the cloth is colorless (i.e. insoluble), it indicates that the paint film has completely cured before proceeding with the next coat of paint
The maximum coating interval time for 704 inorganic zinc primer is not limited, but before applying the next coat of paint, the zinc salts formed on the surface must be removed, otherwise it will affect the interlayer adhesion and protective effect of the paint film
Used as a workshop primer for steel pretreatment production lines in shipyards, heavy machinery factories, and other industries. It can also be used as high-performance anti rust paint for steel columns on offshore platforms, steel supports in mines, bridges, and large steel structures.
