NITRATE-FREE CATALYST FOR HIGH-GRADE-FINISH TEXTILES
Substantially nitrate-free catalysts for high-grade-finish textiles with formaldehyde-free wetting agents, containing magnesium, tetrafluoroborate, chloride and sulphate ions in the molar weight ratios of (a) Mg<2+> : BF4<-> = 1 : 0.1 to 4, (b) Mg<2+> : Cl<-> = 1 : 1.7 to 15, and (c) SO4<2-> : Cl<-> = 1 : 0.2 to 4.
