Nullifire S708 Waterborne Basecoat is a white thin film intumescent coating for the fire protection of internal or semi-exposed structural steelwork.
Nullifire S708 is an eco friendly alternative to solvent based products. It is a water based intumescent coating for semi-exposed structural steelwork against fire for 60 minutes. With full external durability throughout the building phase, it is compatible with a full range of Nullifire primers and top seals. No top seal required in C1 and C2 environments. This product also benefits from a very low VOC in comparison to traditional solvent based coatings.
