Water-based fire-retardant paints are environmentally friendly coatings that are easy to apply, dry quickly, and have a low toxicity level. They are ideal for protecting metal structures, such as steel, from exposure to fire. These paints form a heat-resistant layer that slows down the heating process of the material and prevents it from burning, and also significantly increases the time during which the metal retains its strength when exposed to high temperatures. Water-based fire-retardant paints are often used in construction and industry to protect buildings and structures where strict fire safety standards are required.
