GraviHEL alkyd primer grey TDS
One-component priming coat based on an alkyd binder, used as anti-corrosion protection of steel surfaces. It is distinguished by extremely quick drying (approx. 20 minutes), it is also suitable for application by immersion. Brush application is only suitable for smaller surfaces, as more coats are required to achieve the recommended thickness of dry film compared to spraying application. With a film thickness of up to 25µm, it enables subsequent welding without any effect on the quality of the weld. Combined with an adequate top coating, it is suitable for exposure in a countryside, city or mild industrial atmosphere.
The primer can be shaded with GraviHEL pastes according to the RAL colour chart or sample.
The recommended ratio between the binder and the pastes is 85 : 15.
