Solvent Red 1
Solvent Red 1 (C.I. 12150), also known as Sudan Red G, delivers a clear, highly transparent, and vibrant color tone without any dullness. Characterized by stable physicochemical properties, strong acid and alkali resistance, and excellent dissolution uniformity, it is a highly versatile, general-purpose basic solvent red dye.
Driven by its core advantages of high cost-effectiveness, broad system compatibility, and stable processing performance, it, alongside solvent blue dyes, is widely applied in the coloring of plastics, printing inks, coatings, oils, waxes, and fine chemicals. Furthermore, it serves as a fundamental core colorant in industrial color matching for formulating warm reds, orange-reds, and vintage reds.
Basic Features
Printing Inks: Suitable for gravure, screen, and flexographic solvent inks. Widely used for transparent red coloring, delivering uniform color reproduction without mottling.
Oils & Waxes Coloring: Excellent for coloring industrial lubricants, fuel identification oils, artisanal candles, hot-melt waxes, and premium shoe polishes. Delivers a clear, warm, and translucent finish, with no color floating or tacky residue.
Transparent Coloring for Rubber & Plastics: Specially designed for transparent plastics such as PS, ABS, PMMA, PC, SAN, and RPVC. Perfect for coloring transparent plastic accessories, stationery, and optical components.
Fine Daily Chemicals & Industrial Additives: Versatile applications in oil-based marker inks, resin epoxy glues, leather oil-based finishing agents, insulating oil coloring, and laboratory acid-base indicators.
