PRODUCT PROFILE
S.R.23Solvent Red 23 — grade profile
Solvent Red 23 (S.R.23) is a azo solvent dye for coloration in Plastics & masterbatch, Coatings & paint and Printing inks. 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 250 °C. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Polystyrene (PS), PMMA and ABS.
Selection focus
Confirm polymer compatibility, transparency, dissolution, actual melt temperature, loading, and migration and light-fastness requirements in the finished article.
