Intumescent Based Fire proof Coating

Intumescent fire proofing paint (IFC code ™ 136 ) of Afzir Retrofitting  Company, can be a suitable coating to protect steel structures against fire and flames. The main advantage of this type of coating over other coatings such as mineral coating materials is their beauty and lightness. Because this product itself can be used as a final surface coating. The light weight of these materials are generally not effective in structures. But if these materials are used in high-rise steel structures, it is better to consider its weight in the calculation and design of the structure. These paints are applied with a maximum thickness of 6 mm and finally create a smooth surface and resistant to abrasion and dust. This product of Afzir Company can protect steel from fire for up to 3 hours. This type of paint can be used in the interior of the building (beams, columns, pipes and chimneys).


PRODUCT DESCRIPTION

Intumescent coatings are paint like materials which are inert at low temperatures but which provide insulation as a result of a complex chemical reaction at temperatures typically of about 200-250°C. At these temperatures the properties of steel will not be affected. As a result of this reaction they swell and provide an expanded layer of low conductivity char.

Key Features


  • Smooth and durable surface against abrasion and dust
  • Has a thin coating
  • An affordable solution
  • Easy repairs
  • Compatible volatile organic compounds
  • In accordance with modern world standards
  • Ability to protect the structure against fire for up to 3 hours

Applications


  • In general, intumescent paint can be used to reinforce structures that are relatively large, such as shopping malls and airports.
  • Suitable for beams, columns and interior spaces
  • Suitable for pipes, gutters and chimneys
  • Suitable for large structures such as industrial plants, production units, parking of commercial complexes
  • Can be used in public spaces for families, railways and car terminals
  • Can be used in ports and high environments

Application Instructions

For processing, the surface temperature should be 25 degrees Celsius. Also, the final setting time of the intumescent paint is 24 hours. After this time, the final coating can be applied on the surface.

How to use

Interior

Application is performed through a three step process.

The first step of the intumescent system is the application of a compatible steel primer to the steel substrate.

Next, the intumescent base coat is applied to the primed steel substrate to the required thickness. This layer provides the fire protection to the structural member.

Finally, a decorative and protective top coat may be applied over the installed intumescent coating. This finish coat can be any color and gloss level and should be a material that will protect the intumescent coating against high humidity and other potentially harsh interior environmental conditions, while providing a smooth, attractive, architectural finish.

Exterior

Application is performed through a four step, process.

The first step of the intumescent system is the application of a compatible steel primer to the steel substrate.

Next, the intumescent base coat is applied to the primed steel substrate to the required thickness. This layer provides the actual fire protection to the member.

Then, Afzir intumescent paint is coated with two coats of Spray Film Top seal.

Finally, a decorative and protective top coat shall be applied over the installed Top seal. The exterior finish coat can be any color and gloss level and must be specifically approved for use by Afzir Company. This exterior finish coat will protect the Afzir intumescent paint system, while providing a smooth, attractive, architectural finish.

Frequently Asked Questions

What is intumescent paint?

intumescent paints or coatings help to increase the building's fire resistance. These coatings expand when exposed to extreme temperatures. Coatings lose their density as they shrink. As a result, they act as an insulator.

What is the advantage of intumescent fire retardant paints?

The significant advantage of this type of coating over other coatings, such as mineral coatings, is their beauty and lightness. Because this product itself can be used as a final surface coating.

What is the maximum thickness of intumescent paints on surfaces?

intumescent paints are applied with a maximum thickness of 6 mm and finally create a smooth surface and resistant to abrasion and dust.

On what surfaces are intumescent fire retardant paints most commonly used?

intumescent fire-retardant paints are used on steel structures, and in general, intumescent paints can be used to reinforce large-scale structures, such as shopping malls and airports, against fire.

What is the durability of intumescent paints against fire?

These paints give more resilience to steel surfaces for up to 3 hours.

In what colors are intumescent fire retardant paints produced?

Expandable fire retardant paints are light pink.

How long does it take for the intumescent paint to reach its final setting?

The final setting time of the intumescent paint is 24 hours. After this time, the final coating can be applied on the surface.
