Fire Retardant Coating for Ducts
Fire Retardant Coating for Ducts is a specialized protective coating applied to HVAC ducts to reduce the spread of fire and smoke through ventilation systems. These Fire Retardant coatings play a critical role in passive fire protection, especially in commercial, industrial, and high-rise buildings where ducts can act as pathways for fire propagation.
What It Does:
Slows down flame spread along duct surfaces
Reduces smoke generation and toxic fumes
Enhances fire resistance of GI, MS, and aluminum ducts
Helps maintain structural integrity of ducts during fire exposure
Key Features:
Intumescent action: Expands when exposed to heat, forming an insulating char layer
High fire rating: Designed to meet fire resistance requirements (as per ASTM, BS, UL, or IS standards, depending on product)
Durable & flexible: Withstands vibration, temperature variations, and normal duct movement
Low smoke & low toxicity: Suitable for enclosed and occupied spaces
Good adhesion: Excellent bonding to metal duct surfaces
Types of Fire Retardant Coatings for Ducts
Water-based fire retardant coatings: Eco-friendly, low VOC, easy application
Solvent-based fire retardant coatings: Higher durability in harsh environments
Intumescent fire retardant coatings: Expand under fire to provide thermal insulation
Application Areas:
HVAC supply and return air ducts
Kitchen exhaust and smoke extraction ducts
Fire-rated ducting systems
Commercial buildings, malls, hospitals, airports, hotels, and industrial plants
Application Method:
Surface cleaning and degreasing of ducts
Application by brush, roller, or spray
Achieving specified Dry Film Thickness (DFT)
Proper curing as per manufacturer guidelines
Benefits:
Improves overall building fire safety
Limits fire and smoke spread between compartments
Supports compliance with fire safety regulations
Cost-effective passive fire protection solution
Fire Retardant Coating for Ducts is an essential safety measure for modern buildings, ensuring safer evacuation, reduced fire damage, and enhanced compliance with fire protection standards.
