There are several types of fire-resistant coatings for ventilation ductwork, including:
1. Intumescent coatings - These coatings expand under high heat or fire conditions and create a protective carbonaceous char layer, preventing the spread of fire.
2. Cementitious coatings - These coatings are made of a blend of cement, water, and other ingredients that create a hard, durable surface when cured. They provide excellent fire resistance, but they may not be suitable for all types of ventilation ducts.
3. Ceramic coatings - These coatings are made of ceramic fibers mixed with binders and can withstand high temperatures. They are often used in high-temperature applications.
4. Silicone coatings - These coatings are made of silicone elastomers and provide an excellent barrier against fire, smoke, and water.
5. Epoxy coatings - These coatings are made of epoxy resins and provide a durable and strong surface that can withstand high heat and fire. They are often used in industrial and commercial settings.
