Synthetic Primer
Application of Synthetic Primer
It is ready for use upon delivery (after stirring) and may be applied to a clean, grit blasted steel pipes by spraying (or brushing). For normal thicknesses (dry film thickness 20-30μm, wet film thickness 100μm). The primer coverage rate is 10 m2/liter. The wet film thickness may be regulated by ±20 μm, which will result in a variation in dry film thickness of 5μm. At 25°C ambient temperatures and under normal ventilation the drying time varies from 4-12 minutes depending on pipe temperature. During application, the pipe temperature should be between 10-50°C and at least 3°C above dew point.
