Refractory Rigidizer for Ceramic Fiber Blankets - 16 Ounces 2300°F High Temperature Kaowool Surface Hardener for Forges, Kilns & Foundry Furnace - Prevents Fiber Erosion & Airflow Damage

Enhance the durability and performance of your ceramic fiber blankets with our specially formulated Refractory Curing Agent. This high-quality curing agent is designed to provide superior bonding and strength to ceramic fiber insulation, ensuring long-lasting protection in high-temperature applications

• Forms a hard shield withstand extreme temperatures up to 2300°F (1260°C) – Stops ceramic fibers from breaking loose in high-heat DIY projects like forges or smelting foundry
• Just Spray & Dry. No mixing needed. Pre-wet blanket with water, spray until saturated, install while damp – cures naturally in 48hrs or heat-gun for faster setup
• Withstands 30m/s gas flow – 3X more erosion-resistant than untreated blankets. SiO₂-based formula, non-toxic when cured
• 16oz covers 2-2.5 sq ft (0.17-0.2 m²) – Comes with adjustable trigger sprayer
• PREVENTS costly repairs. Stops fiber dust in air (lung hazard) and insulates 25% better – Saves you from rebuilding furnace linings
• This curing agent is semi-transparent, will not change the color of the original blanket/wool
• Please Note: The effect of the curing agent is not permanently. It will gradually lose its effectiveness over time. Just need to repeat the application again
• When the temperature is below 32°F(0℃), the rigidizer may freeze. Place the bottle in warm water to thaw it, and then it can be used normally without affecting its performance.
