About “Passive Fire Protection”
In the case of Paints, Varnishes and Liquids, passive protection means the active elements remain dormant until activated by heat or flames,
The first aim of Passive Fire Protection is to limit the spread of fire and smoke as determined by the local building and fire code. This is done with a fire retardant product.
The outbreak of a fire triggers these special coatings to change from apparently normal decorative finishes into an active protection layer applied to a variety of materials and surfaces, including walls, doors, ceilings, flooring and more, They are designed to reduce the spread of flame and reduce dangerous smoke and toxic gasses.
The other Passive Fire Protection coating in common use is fire resistance usually in the form of an Intumescent coating. In intumescent paint and coatings (for wood & timber, steel, structural steel and cast iron), the active ingredients swell and char to create a thermal barrier when exposed to heat and flame that keeps the substrate below critical temperatures. (Take a look at our amazing TV demo). In many cases intumescent coatings should be coated with a flame retardant finish that gives off gasses to inhibit the spread of fire and reduce the amounts of smoke and flaming droplets thus further protecting the building, and importantly, the lives of those who may be inside it.
