POWERSOFT® AE 66 is particularly suitable for the impregnation of fibers and textiles. POWERSOFT® AE 66 imparts a very soft, smooth and elastic touch, additionally to woven and knitted fabrics. POWERSOFT® AE 66 improves the wash-and-wear properties and the crease recovery angle and tear strength and reduces abrasion loss. The effects are fast to washing and dry cleaning.

POWERSOFT® AE 66 has very little effect on the degree of whiteness when usual application conditions are adhered to. Generally, no adverse effect on the shade or color fastness properties of coloured goods is observed.

Specific features of POWERSOFT® AE 66

  • Concentrate


POWERSOFT® AE 66 gives permanent effects even without the addition of a catalyst. Specific curing conditions need not be adhered to if no resins are used.

POWERSOFT® AE 66 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 POWERSOFT® AE 66 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. POWERSOFT® AE 66 can be applied either alone or together with resins and other finishing agents. If POWERSOFT® AE 66 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 POWERSOFT® AE 66. A wide range of touches can be obtained by combining POWERSOFT® AE 66 with conventional softening agents and other additives such as fillers based on polyacrylate.

The "Best use before end" date of each batch is shown on the product label.

Emulsions showing signs of creaming should be agitated before use to assure uniform consistency.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
