    Intumescent Coatings For Steel

    Ark Fire Protection are one of the specialists in fire protection services with one core focus – protecting people and buildings from fire. Intumescent coatings are used in conjunction with other fire protection elements to achieve Passive Fire Protection.

     

    Ark Fire Protection can apply Intumescent Coatings to structural steel to ensure they are capable of withstanding high temperatures and ensure the structural stability of the building.

    The Basic Principle of Intumescent Coatings

    Intumescent Coatings for Fire Protection

    Intumescent coatings for structural steels are a proven and effective method of protecting buildings from the risk of structural damage. All of the intumescent coatings used by Ark Fire Protection have been rigorously tested, meeting EU standards, giving confidence to our customers of advanced protection from fires which may cause threats to the structural elements of buildings.

     

    Intumescent coatings, often referred to as reactive paint, reacts with the heat caused from a fire, specifically temperatures exceeding 120°C. When exposed to temperatures above this threshold, the paint will intumesce (swell) up to 50 times the thickness of the original paint forming a proactive, carbon layer which thermally insulates the steel for a set period of time. Depending on the coating, this is usually in the range of 30 – 120 minutes. This period allows people to be safely evacuated from the building and protects the very structure of a building before firefighters can extinguish the blaze.

    Before & After Exposure

    What is Critical Temperature?

    During a fire the high temperatures reach can have a detrimental impact to the structural properties of steel. At 300°C the steel’s strength has already been compromised. When the temperature exceeds 400°C the structural strength of the steel has significantly decreased by 60%. A typical building fire reaches temperatures around 1000°C giving context to how immense heat impacts structural steel.

     

    The critical temperature for structural steel typically ranges between 550°C – 650°C. At this critical temperature the structural steel will no longer be capable to support the weight of the building. Steels will start to distort and collapse.

    When is Intumescent Paint Required?

    Intumescent Coatings are applied to buildings to delay the spread of fire as outlined in the standards set by BS 476 Parts 20 – 23 1987. These coatings are categorised by time, such as “30 minutes”. Our intumescent paint systems are available for both steel and timber structures –  and are often specified by building control authorities in the UK.

    Cementitious Coatings

    Cementitious fire protection is usually sprayed on successive layers of steel or concrete to protect from the devastating effects of fire and protecting the structural integrity of the building. Cementitious material is produced by mixing it with water to create a uniform slurry mix that is then pumped to a nozzle and sprayed directly onto the substrate. This helps reach all the hidden gaps for complete coverage.

    How Do Cementitious Coatings Differs From Intumescent Coatings?

    Cementitious coatings are similar to intumescent coatings however they do not produce black smoke, char or expand when exposed to fire. Cementitious coatings are relatively inexpensive and are extremely effective at withstanding high temperatures.

    The two types of intumescent coatings, Soft Char and Hard Char

    Soft char

     

    Soft char intumescent paints generate a light char, which is a fantastic heat retardant. In the event of fire, water vapour (the hydrates), is released resulting in a cooling effect. Once all the vapour has been released, the remaining char will slow the heat transfer to the substrate. We use soft char intumescent paints primarily to protect structural steel internally.

     

    Hard char

     

    Hard char intumescent paints produce a harder char, which is another brilliant fire retardant. Harder chars are made with sodium silicates and graphite. These paints are mainly used for plastic pipe protection, however can be used for steel fireproofing.

    What are the Benefits of Using Intumescent Coatings?

    How Much Does Intumescent Paint Expand and Why is That Important for Fire Safety?

    A thin-film coating of intumescent paint will expand at a rate of 50:1, whereas a thick-film coating expands at a rate of 5:1, as a general rule. This expansion generates a microporous carbonaceous foam that significantly slows down the heat flow from the fire to the surface beneath it. This buys valuable time for individuals to escape the building, or for firefighters to extinguish the blaze.

     

    Intumescent coatings work by protecting steel surfaces from the high temperatures of fire. They act as an insulator, therefore keeping the structural integrity and shape of the steel as it should be; in turn, preserving the safety of the bulding that it is supporting. The application of intumescent coatings can be undertaken in multiple different ways. It can either be applied by hand or through spraying. We can apply intumescent coatings with leading applications such as the Putzmeister SP11 which will deliver a great finish.

    Working With Leading Manufacturers

    Intumescent Paint Frequently Asked Questions

    What is intumescent paint?

    Intumescent paint reacts when its temperature is, or exceeds, 120°C. This results in a soft charring effect at its surface (which insulates and reduces transmission of heat into the substrate) and the release of water vapour, which cools the substrate.

    What does intumescent mean?

    An intumescent is a substance that swells as a result of heat exposure, thus leading to an increase in volume and decrease in density. Intumescents are typically used in passive fire protection.
