Solvent Blue 70 CAS 12237-24-0 supplier

Solvent Blue 70 (C.I. 61551, CAS No. 12237-24-0) is a metal-complex solvent color. Its chemical framework comes from the phthalocyanine or copper-complex system, providing crucial advantages such as vibrant color, superb fastness, and high security.

In appearance, Solvent Blue 70 is a deep blue to dazzling blue powder that liquifies quickly in organic solvents like toluene, xylene, alcohols, esters, and ketones, yet is insoluble in water. It has a melting point of roughly 175– 180 ° C, wetness material listed below 5%, and a pH normally ranging from 5.5 to 7.5.

As a “solvent dye,” it accomplishes tinting through dissolution rather than dispersion. Unlike pigments, which stay put on hold as fine particles and may work out with time, Solvent Blue 70 completely dissolves, creating clear, particle-free, and highly lustrous tinted systems. This characteristic makes it perfect for applications needing high openness and mirror-like coatings, such as wood varnishes, metallic overcoats, and light weight aluminum foil marking products.

In regards to color, it looks like a somewhat green brilliant blue– in some cases called “skies blue” or “green blue.” Minor shade variations might happen between sets from different suppliers; as a result, when purchasing in bulk, it’s recommended to demand color examples for confirmation.

Wood Coatings and Furnishings Coloring– Among the biggest application areas. When contributed to American-style coatings, PU, NC, or UV paints, it produces a transparent yet rich blue effect without obscuring the all-natural wood grain. Due to the fact that it dissolves totally, it does not mask the timber structure yet rather enables the underlying patterns to show clearly.

Publishing Inks and Product Packaging Materials– Utilized in gravure and flexographic printing to accomplish blue tones on light weight aluminum foil, gold/silver cardstock, and PVC/PET films. It is also typically utilized for tinting light weight aluminum foil stamping products and vacuum-coated plastic parts.

Leather and Fabric Dyeing– Ideal for natural leather immersion dyeing and surface area spraying, where great penetration, migration resistance, and colorfastness are called for. Solvent Blue 70 carries out well in these facets and is frequently made use of in footwear polish, leather coats, and handbag production lines.

Metal Design and Stationery– Utilized to create blue tones in metal finishes, clear topcoats, and baking-type paints. Furthermore, the blue ink in your oil-based pen or ballpoint pen likely includes this color.

Eyeglasses and Decorative Materials– Transparent blue coverings on high-end eyeglass frameworks and decorative panels are commonly achieved utilizing this color.
