WACKER^® FINISH CT 64 E

Processing:

WACKER^® FINISH CT 64 E gives permanent effects even without the addition of a catalyst. Specific curing conditions need not be adhered to if no resins are used.

WACKER^® FINISH CT 64 E 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. 5 - 30 g/l WACKER^® FINISH CT 64 E are recommended for the pad method. For the exhaust method 1 - 3 %, 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. WACKER^® FINISH CT 64 E can be applied either alone or together with resins and other finishing agents. If WACKER^® FINISH CT 64 E is used together with crosslinking agents and other additives, it should be added, in diluted form, after all the other products. (This recommendation applies generally to the processing of all polysiloxanes). Higher crease recovery angles and lower abrasion values can be obtained in resin finishes by using WACKER^® FINISH CT 64 E. A wide range of touches can be obtained by combining WACKER^® FINISH CT 64 E with conventional softening agents and other additives such as fillers based on polyacrylate.
