Optifire+ is a unique and impossible to manipulate pigment. With Optifire+ we can be sure, at any time after the project is completed, that the product specified is the product applied – confidence that the materials submitted through the approval processes are installed to protect customer's assets.
Optifire+ is invisible to the naked eye and is added to Nullifire intumescent steel coatings. It can be identified with the traceability tool.
As a product identifier, Optifire+ doesn’t change the way intumescent coatings work. But it does stimulate that they are used and are applied correctly. Nullifire intumescent steel coatings can’t be altered without it being visible and application can be checked afterwards.

| Steven Storey on 2021-11-12 12:47:25 | Question:
How many sq/m does 1tin of Nullifire sc802 cover? |
Answer from Rawlins’ Technical Team:
Intumescent paints like this do not have a specific coverage rate, the level of fire protection required and the steel dimensions will dicate the quantity required. We can assist with a specification for the steels we would require the information below sent to [email protected] - Level of fire protection required (i.e. 30, 60, 90min, etc.) - Each steel section dimension (i.e. 254x146x37 UB) - Quantity and length of each section (or overall meterage for each section) - Orientation (horizontal or vertical) - Number of sides to be painted (all sides, 3 sides, 1 flange, etc.) - Structural Steel Design Code (i.e. EuroCode, BS5950, BS476; Part 21, etc.) - Building type (i.e. office, domestic, storage, etc.) - Environment (internal, external, car park, chemical exposure, etc.) - Application on site or in shop Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them but in that instance we'd need some guidance as to what to allow for i.e. all steels on first floor, etc. | |
| Darran nixon on 2020-01-02 16:12:48 | Question:
once i have applied the base coat with the 60 minute fire rating can i use a water base eggshell on top for colour purpose ? |
Answer from Rawlins’ Technical Team:
We can only recommend that you apply a Nullifire compatible topcoat such as Nullifire TS816 or Nullifire TS134 over SC802 as these have been tested to ensure in the event of the fire they don;t cause any issue for the intumescent paint. | |
| Richard Bennett on 2017-04-26 09:22:11 | Question: Can you confirm the dimension that needs to be allowed for expansion of 90min intumescent paint, i.e. the minimum clear dimension between the coating and any cladding, framing and associated obstructions.
Many thanks. |
Answer from Rawlins’ Technical Team: Expansion Gap for 90min FR would be 50mm or 50x DFT. For 60min we can reduce gap to 30mm. | |
