NADIS Sodiumdisilicates
..............................................

Sodiumdisilicates control the pH value of the washing water. They facilitate a slight swelling of the fibers and thereby increase the washing power of the detergent. They also help to maintain the distribution of the dirt partic¬les in the washing liquid and bind the dissolved iron, which in turn reduces yellowing of the fabric. Furthermore, Sodiumdisili¬cates protect the washing machine from corrosion.
Because of it low bulk density, NADIS™ 100G is also used to adjust the bulk density of the detergent.
NADIS™ 20D is an integrated manufactured Sodiumdisilicate compound with a non-ionic surfactant. It allows a simpler dry-blending production, because it already contains one crucial component.
Over and above a certain minimum quantity, Silkem can produce any compound, if technically possible, ac­cording customers’ requirements.
