Overview
Toluidine Maroon Pigment, also known as Pigment Red 3, is a synthetic organic pigment derived from toluidine. It is prized for its vibrant reddish-brown hue and is widely used in industrial applications. The pigment belongs to the azo dye class and is known for its excellent color strength and durability. First developed in the early 20th century, Toluidine Maroon has become a staple in the coatings and plastics industries. Its versatility and cost-effectiveness make it a preferred choice for manufacturers seeking consistent and high-performance colorants.
Physical and Chemical Properties
Toluidine Maroon Pigment is a fine, reddish-brown powder with a molecular weight of 307.30 g/mol. It is insoluble in water but dissolves readily in organic solvents like alcohols and ketones. The pigment exhibits high tinting strength, meaning a small amount can produce a vivid color. Its lightfastness and chemical resistance make it suitable for outdoor applications. The pigment is stable under normal conditions but may degrade when exposed to strong acids or alkalis. Proper storage is essential to maintain its quality over time.
Main Applications
Toluidine Maroon Pigment is extensively used in the paints and coatings industry for automotive finishes, architectural paints, and industrial coatings. Its excellent opacity and color stability make it ideal for these applications. In the plastics sector, the pigment is used to color PVC, polyethylene, and other polymers. It is also a popular choice for printing inks, textiles, and artistic paints. The pigment's versatility and performance characteristics ensure its widespread use across multiple industries.
Safety and Storage
While Toluidine Maroon Pigment is generally safe when handled properly, precautions should be taken to avoid inhalation or skin contact. Personal protective equipment (PPE), such as gloves and masks, is recommended during handling. The pigment should be stored in a cool, dry place away from direct sunlight and moisture. Containers must be tightly sealed to prevent contamination and degradation. Proper storage conditions help maintain the pigment's quality and extend its shelf life.
B2B Procurement Guide
When procuring Toluidine Maroon Pigment, B2B buyers should prioritize suppliers with certifications like ISO or REACH compliance. Batch consistency and purity levels (typically 95-98%) are critical for ensuring product performance. Price ranges vary based on quantity and supplier, but buyers should expect to pay approximately $5-$15 per kg. It's advisable to request samples for testing before large-scale purchases. Additionally, consider logistics and storage requirements to avoid delays or quality issues.
