fire-protective-composites Finnester Coatings claims to have cracked the toughest requirement in fire safety of composites - flame spread. Many industries have standards for fire safety. All the standards consist of similar parameters, among which Flame Spread is the toughest to reach with fire resistant composites.

Unique Technology for High-standard Fire Protection


Traditionally, when fire protection is required for a composite, the protection is built in the composite itself with different available methods, e.g. by adding specialty resins or intumescent gelcoats. Mostly, there is also a need for some esthetic appearance for the fire protective composite material and here comes the problem. If the composite is painted with an organic paint, it will not pass the Flame Spread requirement of any standard, because fire spreads rapidly on a painted surface.

Finnester Coatings started looking at this problem from the outside layer and solved it with a ceramic fire protective coating. The unique ceramic technology is the first to cover all necessary parameters in fire protection so that nothing must be done to the composite material it covers. When exposed to fire the coating forms a ceramic shield which does not produce a flame. Unlike intumescent fire protection solutions, the ceramic shield keeps its fire-protective properties even outdoors.

Preventing Flame Spread While Maintaining Structural Integrity


The coated composite structure needs to pass a range of other parameters as well. The RED coating solution also prolongs ignition times and gives the substrate a low heat release rate, withstanding temperatures up to 1000°C without losing the structural integrity. Having achieved all this with a coating, the coated composite still has all its original properties required for the application.

Fire protection as such is never the only requirement when material choice is evaluated. Composites have many advantages, they are lightweight, easily processable, strong, and require little maintenance. When fire protection is included in the composite material itself, with any method, all these original advantages are weakened considerably. With RED coating, the original material is not compromised and furthermore, the substrate is covered with a surface that also gives protection against weather conditions and vandalism. And as a decorative solution it offers a smooth and gloss finish with a variety of colors.

Passing The Toughest Fire Standards


Finnester Coatings constantly finetunes and tests its product in its own fire lab and after years of development work, they have announced that their RED coating solution passes all the toughest requirements for fire safety, as the first in the composite world! RED coated composites can be used for applications requiring IMO Part 5 in marine, EN 45545-2 HL1-3 for passenger rolling stock in all categories and EN 13501-1 class B for construction.
