Surface Treatment
All
surfaces should be clean, dry and free from dirt, and the surface should follow
ISO8504 before evaluation and processing.
Bare
steel
Cleanliness:
Sand blasting to a minimum of Sa 2 1/2(ISO 8501-1:1988) or ultra-high
pressure spray water treatment to WJ 2 during maintenance (NACE No.
5/SSPC-SP
12). Roughness: Treated
to fine to medium (30-85 μm, Ry5) (ISO 8503-2) with angular sand (G).

Other
surfaces
This
product can be applied on another substrate. Refer the details to the company.
Engineering Conditions
Substrate
temperature must not be lower than 10°and should be at least 6°or more above
the dew point of the air. Temperature and relative humidity should be measured
near the substrate. In narrow area, good ventilation is usually required to
ensure proper drying.
Manner of application
Spray
coat Use airless spray or air spray.
Brush
coat It is recommended for pre-coating
and small-area coating, but the required dry film thickness must be achieved.
Roll
coat It can be used in small areas,
but it is not recommended as the first
primer . In the case of roller coating, sufficient materials must be applied to
achieve the specified dry film thickness.
Engineering Specs
Mixing
ratio (mass ratio): component A:component B=5:1, stir evenly. To
ensure proper mixing, the two components are mixed. Use a mechanical stirrer to
stir the mixture, and use a mechanical stirrer after mixing the two components.
Stir evenly (at least 1 minutes).
Service
life after mixture (23℃): 4hours.Attn: The paint can no longer be used beyond
its service life. It is recommended to use the alarm notice before its expiry.
Thinner/cleaner:
Clean water.
Spraying
parameters: When applying by spray coating, it is necessary to adjust according
to the actual spraying conditions. It is recommended to test the spray in a
small area and obtain the proper spray parameters before coating.
Drying
time
Factors such as ventilation conditions,
temperature, film thickness, and coating degree will affect drying time.

Other information
Construction equipment preparation and cleaning
procedures
In order to avoid contamination of the waterborne
paint by the solvent, the spray equipment must be properly adjusted before use.
All solvent-contacting pumps, tubes, guns, etc. must be thoroughly cleaned
according to the following steps:
If the construction equipment is made of stainless
steel and is used exclusively for the construction of waterborne paints, this
preparation and cleaning work is not required.
Before spraying: Rinse with water in equipment and
pipes until it is thoroughly clean.
After spraying: Rinse the equipment and piping with
water and leave no residual paint.
Storage
It must be stored in accordance with national
regulations. The storage environment should be dry, cool, well ventilated, and
away from sources of heat and fire. The packaging container must be kept closed
and frozen.
Storage life:23°C,Component A,1year;Component B,1 year Then it is necessary to check again to determine. The
increase in storage temperature will significantly shorten the storage life.
Loading
Loading with caution. Stir evenly before use.
