WB-SOFTENER is a formaldehyde-free additive designed specifically to reduce the print’s hand (softness) in all aqueous ink systems. Add 2-3%, by weight, to your discharge or water-based inks. Up to 5% maximum, by weight, can be added. The maximum addition level should not be exceeded as this may adversely affect the printed fabrics wash fastness. WB-SOFTENER also improves the “flow” characteristics of the ink and prevents drying-in /choking in the screen without any adverse effect on flash performance of the ink.
