Sacrificial sprays are protective coatings applied to surfaces, particularly in industries like automotive and aerospace. These sprays create a barrier that absorbs damage from environmental factors, such as corrosion, UV rays, and physical wear. When the coating wears away, it protects the underlying material, extending the lifespan of the component. These sprays are often used on metal surfaces, such as those found in vehicles and aircraft. By sacrificing themselves, they prevent more significant damage to the base material, reducing maintenance costs and improving overall durability. This makes sacrificial sprays a valuable tool in preserving the integrity of various products.
