• Application: Pigment Red 254 is a versatile red powder known for its vibrant shade and excellent performance characteristics. This pigment is primarily used in the preparation of high-performance polyurethane waterborne waterproof coatings. Its desirable properties include exceptional heat resistance of up to 300°C, superior light fastness rated at 8, and robust resistance to both acids and alkalis, each rated at 5. Additionally, Pigment Red 254 demonstrates impressive fastness to bleeding, ensuring long-lasting color stability. It is synthesized to maintain an optimal oil absorption rate of 40-50%, a specific surface area of 28 m²/g, and a density of 1.60 g/cm³. The purity and quality of the pigment are further emphasized by a maximum allowable residue on 80 mesh of 5.0% and minimal water solubility and volatility at 105°C, each at 1.0% max. With a tinting strength of 100-105%, Pigment Red 254 offers reliability and consistency for industrial applications.
