Scarlet Chrome
Scarlet Chrome is a vibrant, high-quality inorganic pigment primarily composed of lead chromate compounds. Known for its brilliant scarlet-red hue, it offers excellent opacity, weather resistance, and durability. Scarlet Chrome pigment is widely used in paints, coatings, plastics, and printing inks where strong, long-lasting color performance is essential. Its chemical stability and resistance to light and heat make it a preferred choice for outdoor applications and industrial finishes.
