Rosner HydRo Primer Filler 1K/2K | Water-Based, Low-Pollutant MDF Primer
The Rosner HydRo Primer Filler 1K/2K is a high-quality, low-pollutant, pigmented, water-based priming coat specifically developed for the coating of MDF. Designed for versatility, this product can be used as a one-component (1K) system or as a two-component (2K) varnish with the addition of the recommended hardener (HydRo Hardener).
This primer filler is essential for creating a flat, uniform varnish structure on your substrates. It is suitable for application on supports such as MDF, primer-coated MDF, lacquer foil coated MDF, or chipboard.
