WATERBORNE PRIMER

Waterborne epoxy gray anti-rust primer

[XGE-HY-（A、B）]

Product Intro

waterborne epoxy iron red anti-rust primer is a two-component quick-drying waterborne epoxy anti-rust primer containing active anti-rust pigments and flash rust inhibitors.

Recommended Applications

Used as a universal primer for steel surfaces in slight and moderate corrosive environments, the surface can be coated with waterborne acrylic, waterborne epoxy, waterborne polyurethane, and suitable solventborne coatings.

Dry film thickness (um)	25	60	40
Wet film thickness (um)	40	100	70
Theoretical coating rate (m2/kg)	12	6	8

Physical character

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).

Steel coated with primer

clean, dry and approved primer

Other surfaces

This product can be applied on other 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：componentB=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℃）is 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             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. Typical data listed in the table below are based on the following conditions:

** Good ventilation (outdoor or natural air circulation) * *Typical film thickness

** Unigrade coating on inert substrates * *Relative humidity 70%

Substrate temperature	10℃	15℃	23℃	40℃
surface dry	80 minutes	60 minutes	45 minutes	45 minutes
solid dry	2 days	2 day	15 hours	10 hours
Solidify	14 day	10 day	7 day	5 day
The shortest coating time interval	24 hours	16 hours	10 hours	6 hours

The above data is for guidance only, actual drying time/The time interval before coating can be long or short, depending on the film thickness, ventilation conditions, humidity, the underlying paint, advance loading and unloading requirements, and mechanical strength. For the complete package, see the corresponding supporting records which includes all parameters and special conditions.

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.
