Strontium chromate is primarily used as a corrosion inhibitor in coatings and primers, especially for aluminum and other metals in aerospace and marine environments. It provides excellent adhesion and enhances the durability of protective coatings, making it ideal for applications where resistance to harsh weather conditions and saltwater exposure is critical. Additionally, it is employed in pigments for paints and coatings, offering a bright yellow color and UV stability. Its use in pyrotechnics is also notable, where it acts as a colorant to produce red flames. However, due to its toxic and carcinogenic nature, its application is increasingly regulated, and safer alternatives are being sought.
