Solvent Red 218 CAS 82347-07-7 | High Transparency Metal Complex Solvent Dye

1. What is Solvent Red 218?
Solvent Red 218, C.I. 61551, CAS number 82347-07-7, is a steel complicated type solvent dye and belongs to high-end oil-soluble dyes.

From an architectural and efficiency perspective, it is developed by the complexation of steel ions with dye molecules. The core benefits brought by this structure are threefold: first, the shade is extremely brilliant; second, the fastness indications are excellent; and 3rd, it has great solubility in natural solvents.

Solubility: It can dissolve alike solvents such as toluene, xylene, butanone, cyclohexanone, alcohols, esters, and so on, and has good compatibility with resin systems such as nitro, acrylic, polyurethane, and polyester.
Tone: It is a red shade with a bluish color. Some individuals additionally call it magenta or pink.
Fastness: Light fastness is at level 6-7, heat fastness can fulfill the processing needs within 200 ° C, and it is at degree 4-5 in regards to acid and alkali resistance, in addition to migration resistance.
Look: Red powder.

The most significant difference between solvent dyes and pigments is that pigments are little insoluble fragments that are spread and suspended in the medium; while Solvent Red 218 is molecularly dissolved, resulting in a clear, particle-free, and highly shiny coloring system. This characteristic establishes its primary application area – any place a “transparent + red” result is required, it is very most likely to be utilized.

2. Where can Solvent Red 218 be made use of?

From the viewpoint of application situations, Solvent Red 218 has a wide variety of applications.
✅️Timber finishes and furniture coloring – This is among the biggest application locations. Adding it to American painting, PU paint, NC paint, UV paint, and acid-cured paint can develop a transparent and distinctive red impact, without covering the all-natural texture of the timber. It is specifically suitable for scenarios where high transparency and high gloss are needed for the finish.

✅️Printing ink and packaging products – It is made use of for shade mixing in intaglio printing and flexographic printing. Red and green colors on light weight aluminum foil paper, gold and silver cardstock, PVC/PET movies, and so on, are mostly made with these dyes. It is likewise commonly utilized for coloring gold foil stamping and warm transfer films.

✅️Natural leather and textile dyeing – Natural leather immersion dyeing, surface spraying. Demands include excellent shade infiltration, resistance to movement, and no shade fading. Solvent Red 218 performs well in these aspects. It is likewise frequently seen on production lines for shoes, leather jackets, and natural leather bags.

✅️Stationery and commercial items – Oil-based pens, ballpoint pen inks, office supplies, baking finishes, plastic layers – all use it for shade matching.

✅️In various other areas – the clear red finish for eyeglass frameworks, the color matching for steel spraying and clear varnish, additionally use this dye.
