Finnester RED technologies

Finnester RED fire protection is based on two different, but compatible, coating technologies that complement each other. With this combination, we can design a coating solution for any type of fire protection parameters.

Finnester RED coating products hybridRED and pureRED are applied directly on non FR composites without interfering with the production of the composite or its uniform structure


hybridRED technology

  • New break-through technology in fire protection of composites based on ceramifying polymers.
  • The coating has a property where the polymer material can continue to provide a protective barrier after the polymer has burned.
  • The barrier is created by formation of a self-supporting ceramic shield over a temperature range where the polymer undergoes thermal degradation.
  • HybridRED offers outstanding fire protection properties in every aspect – except thermal insulation.

pureRED technology

  • Based on unsaturated polyester technology designed to give the best thermal insulation for composites. It is a styrene based MEKP catalyzed system with a wide application window available in RAL colours.
  • PureRED is applied under the ceramic layer of HybridRED. When exposed to fire, the coating forms a thick intumescent layer to provide the substrate with the required level of thermal insulation.

What happens when Finnester RED is exposed to extreme heat?

When exposed to fire, hybridRED forms a protective ceramic shield which is stable. pureRED forms a thick intumescent layer to provide the substrate with the required level of thermal insulation.
