Fire retardant coatings are essential for FRC (Fiber Reinforced Cement) sheets to enhance their fire safety properties. These coatings can significantly reduce the risk of fire spread and limit damage in the event of a fire. Types of Fire Retardant Coatings for FRC Sheets: Intumescent Coatings: These coatings expand when exposed to heat, forming a thick char layer that insulates the FRC sheet and delays the spread of flames. Cementitious Coatings: These coatings are cement-based and provide a protective layer that resists high temperatures and prevents the FRC sheet from contributing to the fire load.
