Non-intumescent coatings are fire protection materials applied to surfaces to enhance their resistance to heat and flames. Unlike intumescent coatings, which expand when exposed to high temperatures, non-intumescent coatings maintain their original thickness and provide a barrier against fire. They are often used on structural steel, wood, and other building materials to help prevent fire spread. These coatings can be made from various substances, including epoxy, polyurethane, and acrylic. They are typically used in commercial and industrial settings, where fire safety regulations require additional protection. Non-intumescent coatings are valued for their durability and ease of application.
