Water-Based Intumescent Coatings
Nullifire pioneered water-based technology, which gives a smooth finish in a faster time than other methods. Given the environmental benefits of water-based coatings then these products are now the preferred choice among specifiers and applicators alike. For 60 minute fire protection Nullifire have now introduced SC802 intumescent coating which gives superior loadings over a wider range of section types, as well as being very easy to spray. For longer time periods up to 120 minutes our water-based SC801 product is recommend, or our high build SC902.
Our water-based systems include:
Solvent-Based Intumescent Coatings
For when environments are semi-exposed then solvent based products still provide an answer in obtaining an excellent finish in a reasonable time frame.
Our solvent-based systems include:
- SC601 Solvent-Based, Intumescent Base Coat
- SC602 Solvent-Based, Intumescent Base Coat
