Dilutions of WACKER® AF 2170 give permanent effects even without the addition of a catalyst. Provided no resins are used, specific curing conditions need not be adhered to. 

Dilutions of WACKER® AF 2170 give permanent effects even without the addition of a catalyst. Provided no resins are used, specific curing conditions need not be adhered to. Dilutions of WACKER® AF 2170 can be applied either by padding or by the exhaust method but, as with all products containing silicone, the finishing liquors should not be subjected to high shear, as this might cause instability. 3-10 g/l of WACKER® AF 2170 diluted to 20 - 30% solids are recommended for the pad method. For the exhaust method 0.5-2%, relative to the weight of goods, are adequate and the treatment should be carried out at 40-50°C for 15-20 minutes. The pH of the liquor should not exceed pH 5. It may need to be adjusted with acetic acid. Dilutions of WACKER® AF 2170 can be applied both alone or together with resins and other finishing agents. If dilutions of WACKER® AF 2170 are used together with cross-linking agents and other additives, it should be added, in dilute form, after all the other products. (This applies generally to the processing of all polysiloxanes). Higher crease recovery angles and lower abrasion values can be obtained in resin finishing by using dilutions of AF 2170 *SMP,1KG. A wide range of hands can be obtained by combining WACKER® AF 2170 with conventional softening agents and other additives such as fillers based on polyacrylate.
