Uses
Dibenzo(b,def)chrysene-7,14-dione (CAS NO.128-66-5) is used to cotton, silk, nylon fabric dyeing printing. It can also be used for communication polyester viscose blend fabric printing. It is brittle sub-light weight, are generally used less frequently is the Wing On dark winter sun. It can be replaced to restore the Yellow GCN and also Brilliant Green FFB fight Green, to restore the yellow color as compared to GCN is much higher. Respectively, and restore it to yellow GCN, restore Yan RF, to restore the red R, Vat Brown RRD, to restore the gray BG and other colors, to make use of mutual adjustment shade. Its printing and dyeing fabric, using urea-formaldehyde or cyanide-aldehyde, DMEU, 2D resin finishing, color very slightly, but in order to BHES resin finishing, color light than the red and dark.
