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.
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.
