Application
Same recommended addition approach as SI Liquid — add after coating mixture is prepared, or to co-binder (PVA, CMC, Starch, Casein) solution. Gives better optical properties (Whiteness CIE, Brightness ISO, Fluorescence, CIE L*a*b*) due to excellent compatibility with all co-binders and high graying limit.
Special feature
Useful for developing high brightness paper with very high fluorescence of international shades where higher OWA dosage is required.
Notes
Can be used in Wet End Application.
