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.

Fire Retardant Coating for Ducts


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.
