Transparent Intumescent Fire Retardant Coating for Homeowners and Businesses
The increasing vulnerability to fires has created an urgent need for innovative fire protection solutions. We, at Researpa, have developed a groundbreaking transparent intumescent coating to protect wooden structures in high-risk fire areas. This case study explores the development, testing, and benefits of this solution, highlighting its impact on fire safety and aesthetic preservation.
The Challenge
Increasing Fire Risks
Electric short circuits, dry climates and extensive woodland areas have lead to increasing cases of fire risks to Homeowners and Businesses.
Balance of Safety and Aesthetics
Traditional fireproofing methods often compromise the natural beauty of wood, leaving homeowners and builders searching for solutions that balance safety and aesthetics.
Solution Requirements
Researpa was tasked with creating a fire-resistant coating that could provide superior fire protection, maintain the natural appearance of wood, and comply with local building codes and standards.
The Solution: Transparent Intumescent Fire Retardant Coating
Innovative Design
Researpa developed a water-based, two-part transparent intumescent coating designed to protect wood while preserving its aesthetic appeal.
Working Mechanism
The coating works by expanding and forming a protective char layer when exposed to heat, insulating the underlying material from fire damage.
Composition
The composition is a 2-part formula and contains water, additives, hardner, and catalyst.
Key Features and Performance
Curing Time
Cures in 4-5 hours.
Durability Development
Develops anti-scratch properties within 24 hours.
Application Window
Pot life of 3 hours for flexible application.
Aesthetic Integrity
Transparent finish that maintains the natural look of wood.
Testing and Validation
Rigorous Testing
Researpa conducted rigorous flame tests to validate the coating's effectiveness. The results demonstrated that the coating formed a robust intumescent layer when exposed to fire, provided superior fire resistance compared to uncoated wood, and maintained structural integrity post-exposure.
A 2-min test was conducted to visualise the formation of char layer, which absorbs the heat and protects wood underneath.
Visual Evidence
Before Fire Exposure: Coated wood retained its natural appearance.
After Fire Exposure: The coating expanded to form a protective char layer, preventing significant damage to the wood.
Comparative tests between coated and uncoated wood clearly demonstrated the effectiveness of the solution in real-world fire scenarios.
