Fire Resistant Coating for Duct

Fire Resistant Coating for Ducts is a high-performance protective coating designed to enhance the fire resistance of HVAC and ventilation duct systems. It helps ducts withstand high temperatures during a fire, limiting heat transfer, fire spread, and smoke movement across fire-rated compartments in a building.

Fire Resistant Coating for Duct


Purpose of Fire Resistant Coating for Ducts:


Provides thermal insulation to ducts during fire exposure

Prevents rapid temperature rise on duct surfaces

Maintains duct integrity for a specified fire-resistance period

Controls the spread of fire and smoke through ventilation systems


Key Characteristics:


High fire resistance: Designed to offer fire ratings such as 30, 60, 90, or 120 minutes

Heat-insulating barrier: Forms a protective layer that reduces heat transmission

Strong adhesion: Bonds effectively to GI, MS, and aluminum ducts

Low smoke emission: Suitable for enclosed HVAC environments

Durable performance: Resistant to vibration, airflow, and temperature fluctuations

Types of Fire Resistant Coatings for Ducts:


Cementitious fire resistant coatings: Robust protection for high-risk areas

Intumescent fire resistant coatings: Expand under heat to form an insulating char lay

Water-based fire resistant coatings: Eco-friendly and easy to apply

Solvent-based fire resistant coatings: Ideal for industrial or harsh conditions


Application Areas:

HVAC air supply and return ducts

Kitchen exhaust and smoke extraction ducts

Fire-rated ducting systems in commercial and industrial buildings

Hospitals, malls, data centers, airports, hotels, and factories


Application Process

Surface preparation by cleaning and degreasing

Application by spray, brush, or roller

Achieving specified Dry Film Thickness (DFT)

Curing as per manufacturer recommendations


Advantages:


Enhances fire safety and compartmentation

Supports compliance with fire safety norms and building codes

Reduces fire damage and smoke spread

Improves overall safety of HVAC infrastructure

Fire Resistant Coating for Ducts is a vital component of passive fire protection systems, ensuring safer buildings and improved fire performance of ductwork.
