Bituseal Primer
Product Description of Bituseal Primer
Bituseal Primer is a specially formulated solvent based steel primer providing excellent adhesion and designed to be completely compatible with Bituseal Enamel.
Application of Bituseal Primer
It is ready for use upon delivery (after stirring) and may be applied to clean and 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 per liter. The wet film thickness may be regulated by ±20μm, 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 5-12 minutes depending on pipe temperature. During application, the pipe temperature should be between 10-50°C and at least 3°C above the dew point.
