Overview
Lake Red, also known as Pigment Red 53:1, is a synthetic organic pigment widely used in industrial applications. It is derived from the coupling of diazotized 2-amino-5-methylbenzenesulfonic acid with 2-naphthol and subsequent precipitation with barium chloride. The pigment is valued for its bright red color and excellent lightfastness, making it suitable for applications requiring long-term color stability. Lake Red is commonly used in inks, paints, plastics, and textiles. Its high tinting strength and chemical resistance make it a preferred choice for manufacturers seeking durable and vibrant colors. The pigment is insoluble in water but can be dispersed in various organic solvents, allowing for versatile application methods.
Physical and Chemical Properties
Lake Red appears as a bright red powder with a molecular weight of 556.14 g/mol. Its density is approximately 1.5 g/cm³, and it is insoluble in water but soluble in organic solvents. The pigment exhibits high tinting strength, meaning a small amount can produce a vivid color. Its lightfastness and chemical resistance are exceptional, ensuring the color remains stable under exposure to sunlight and harsh chemicals. The pigment's stability makes it suitable for outdoor applications, such as automotive paints and architectural coatings. It is also resistant to bleeding and migration, which is crucial for textile dyes and plastic colorants. These properties contribute to its widespread use in industries requiring durable and fade-resistant colors.
Main Applications
Lake Red is primarily used in the production of inks, paints, plastics, and textiles. In the printing industry, it is a key component of offset and flexographic inks, providing vibrant and consistent colors. The pigment's lightfastness makes it ideal for outdoor applications, such as billboards and packaging materials. In the paint industry, Lake Red is used in automotive and architectural coatings, where color stability is critical. It is also employed in plastic products, including toys, containers, and household items, due to its resistance to heat and chemicals. Additionally, the textile industry utilizes Lake Red for dyeing fabrics, ensuring long-lasting and bright colors.
Safety and Storage
Lake Red should be handled with care to avoid inhalation or skin contact. Adequate ventilation is recommended when working with the pigment in powder form. Personal protective equipment, such as gloves and masks, should be worn to minimize exposure. Storage conditions are crucial for maintaining the pigment's quality. Lake Red should be kept in a cool, dry place away from direct sunlight and moisture. Properly sealed containers are essential to prevent contamination and degradation. The pigment is stable under normal conditions but should be kept away from strong oxidizing agents to avoid chemical reactions.
B2B Procurement Guide
When procuring Lake Red, B2B buyers should verify the CAS number (5160-02-1) to ensure they are purchasing the correct product. Purity specifications should also be checked, as impurities can affect the pigment's performance. Buyers should request technical data sheets and certificates of analysis from suppliers to confirm quality. Price ranges for Lake Red vary depending on purity and supplier, typically ranging from $10 to $20 per kg. Bulk purchases may offer cost savings, but buyers should ensure storage capacity is adequate. It is advisable to source from reputable suppliers with a track record of consistent quality and reliable delivery.
