PRODUCT PROFILE
S.Y.179Solvent Yellow 179 — grade profile
Solvent Yellow 179 (S.Y.179) is a methine solvent dye for coloration in Plastics & masterbatch and Textiles & fibers. Grade selection should be verified for polymer compatibility, actual processing temperature, target transparency and migration requirements; the data below is limited to values supported by published sources.
Published screening data includes published heat reference 300 °C. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Polystyrene (PS), ABS, PET and Synthetic fiber.
Selection focus
Confirm polymer compatibility, transparency, dissolution, actual melt temperature, loading, and migration and light-fastness requirements in the finished article.
