Construction conditions
- Painting environment temperature range: 5～35℃. The base surface temperature is at least 5℃ higher than the air dew point temperature.
- Painting environment humidity range: 30～80%.
- Ventilation conditions: Ensure that the construction site is well ventilated and dust-free, and there should be supervisors in confined spaces.
- Note: The paint must be mixed evenly in strict accordance with the proportion marked on the certificate.
Construction method
- Spraying: Use conventional spraying or airless spraying. It is recommended to use airless spraying for large-scale construction.
- Roller coating: Use for large-scale construction.
- Brush coating: Use for small areas. Use a soft-bristled brush or roller brush.

Frequently Asked Questions (FAQ)
What is the mixing ratio for DT-04 primer?
The weight mixing ratio is Primer A component : Primer B component = 2:1. It must be stirred evenly before use.
What is the theoretical coating rate for DT-04?
For a 0.1mm dry coating thickness, roller coating requires 0.15-0.2 Kg/m² of paint, while spray coating requires 0.2-0.3 Kg/m².
How long does the primer take to dry and what is the re-coating interval?
At 23℃, the surface drying time is less than 6 hours (maximum 8 hours) and through drying is less than 24 hours. The minimum re-coating interval is 8 hours, and there is no upper limit.
What are the recommended application methods?
You can use conventional or airless spraying (recommended for large-scale construction), roller coating, or brush coating (recommended for small areas with a soft-bristled brush).
Under what environmental conditions can DT-04 be applied?
The environment temperature should be between 5～35℃, and the humidity range should be 30～80%. The substrate surface temperature must be at least 5℃ higher than the air dew point.
What are the storage and shelf life requirements?
This product should be stored in a cool, dry, and ventilated indoor warehouse. The standard storage period is half a year.
