TremcoNullifire has developed a new intumescent basecoat which has been introduced to enhance the company’s water-based solutions offering.

The new SC804 intumescent basecoat has been designed to provide protection to internal steelwork and should be used within C1 and C2 environments. The latest addition to the SC800 series provides applicators with a product fit to give optimised loadings for 90 minutes; as well as 120 minutes of fire resistance.

Supplied ready for use, SC804 has been formulated for on-site application via airless spray and brush/roller, with fast dry-to-handle times and a recommended overcoat time of sixteen hours. The newest addition to the Nullifire product range has a smooth, matt finish so offers excellent aesthetics.

In the development stage, Nullifire worked closely with a key customer base to ensure a positive experience for all. Nullifire also considered the environmental impact; hence SC804 has an ultra-low VOC, as well as competitive loadings. Supplied in 25kg drums, SC804 provides a theoretical coverage rate of 1,000 g/m² when basing application on an applied 0.5mm dry film thickness.
