Macrofan Airtech Hs Filler

Macrofan Airtech Hs Filler is a fast air‑drying primer/sealer for quick overcoating and sanding. In wet‑in‑wet (MH440) at 20°C it can be recoated after about 5 minutes and allows tape after 30 minutes. For dry‑in‑dry it is sandable after 30–40 minutes at 20°C; low baking at 40–50°C reduces sanding time to 15–20 minutes. Mix up to three primers/sealers to achieve the full grey scale.
