Pigment yellow 151

Pigment Yellow 151 (CAS 31837-42-0 ), commercially recognized under the trade name Hostaperm Yellow H 4G, is a high-performance benzimidazolone azo pigment used across industrial coloration applications. It delivers strong, clean yellow shades with exceptional lightfastness and heat stability, making it a preferred choice where color durability under processing conditions is a primary sourcing criterion. In plastics and polymers, it withstands high processing temperatures, supporting coloration of engineering thermoplastics and polyolefins without shade degradation during the manufacturing process. Coatings formulators use it in industrial and automotive finishes where outdoor durability and resistance to overcoating solvents are required for long-term performance in harsh environments. In printing and packaging, it performs reliably in high-opacity inks for flexible packaging, folding cartons, and laminated substrates, ensuring consistent color quality across various media. Textile and paper applications benefit from its clean hue and resistance to bleed, particularly in pigment printing pastes and paper mass coloration for high-end consumer goods. Pigment Yellow 151 is supplied as a dry powder, with press cake forms available depending on the manufacturer. Standard offerings include both transparent and opaque grades for specific uses. Particle size and surface treatment vary by intended substrate. Technical-grade material is the primary commercial form, with specifications typically aligned to DIN or manufacturer-defined coloristic standards.
