About Lithol Rubine BK-WR Dye

Lithol Rubine BK-WR is a synthetic red pigment dye, typically available as a fine powder. It features a chemical formula of C20H12N4Na2O7S2 and is designed for direct use in various industrial colorant formulations. Supplied in moisture-resistant packaging such as sealed bags and drums, it maintains stability against humidity, ensuring consistent pigment quality during storage and transportation. Buyers should note that the pigment performs best under applied temperatures below 150°C to avoid degradation. It is incompatible with strong oxidizing agents, which can reduce its color intensity and chemical stability. This dye is used predominantly for imparting bright and long-lasting red coloration to medium- and high-density polymer matrices. Its particle size distribution and dispersibility characteristics make it favorable for uniform color expression in complex mixtures. Dosages typically range between 0.5% to 5.0% by weight depending on the medium and desired shade intensity. Proper handling and storage conditions are key to preserving its pigment strength and processing performance.

Why Lithol Rubine BK-WR Dye Matters

In plastics coloration and pigment formulation, Lithol Rubine BK-WR provides consistent red hues that are stable under processing and end-use conditions. Its chemical stability prevents rapid fading or color shifts in polymer or coated products exposed to light and heat. This reliability reduces the risk of batch-to-batch variability and product returns. Furthermore, its powder form with moisture-resistant packaging minimizes handling losses and contamination, improving operational efficiency in manufacturing setups. Maintaining exact pigment concentration with Lithol Rubine BK-WR enables precise color matching critical in branded product identification and quality standards.
