Repellent finishes paraffin repellents

The PERSISTOL types are supplied in the form of aqueous emulsions. They are wash-resistant water-repelling agents derived from paraffin wax or silicone and are used mainly for the water-repellent finishing of outerwear. 

PERSISTOL E is an emulsifier-free, clrconium salt-containing paraffin wax emulsion, which is used as an all-purpose water-repelling agent. It can be combined with the KAURIT and FIXA-PRET types used in resin finishing. 

The RAMASIT types are water-repelling agents derived from paraffin wax. They are used mainly for finishing tent cloths and canvas and for the after-impregnation of textiles. 

Hydrophobic properties are achieved by the application of the water/oU repellent treatment to the substrates (Bahners et al., 2008). The main product groups for this treatment are (1) metal salt paraffin dispersion, (2) polysUoxane and (3) fluorocarbon polymers. The surface of the substrates must be covered with molecules in such a way that their hydrophobic radicals are ideally positioned as parallel as possible, facing outwards, during the chemical finishing with these products.
