WACKER® AF 6
WACKER® AF 6 is a non-reactive aminopropyl functional polydimethylsiloxane.
WACKER® AF 6 is particularly suitable as an active substance in low yellowing softener formulations for the impregnation of fibers and textiles. WACKER® AF 6 imparts a soft, dry handle to woven and knitted fabrics. WACKER® AF 6 improves the wash-and-wear properties and the crease recovery angle, sewability and tear strength and reduces abrasion loss. The effects are fast to washing and dry cleaning. WACKER® AF 6 has very little effect on the degree of white in a softener formulation when usual application conditions are adhered to. As a rule, no adverse effect on the shade or color fastness properties of colored goods is observed.
WACKER® AF 3670 can be applied neat, from solution, or emulsion. Suitable solvents are aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, esters, higher alcohols, and ketones.
Most textile processes are water based. Hence WACKER® AF 3670 is mainly applied from emulsion. WACKER® AF 3670 is suitable for the formulation of micro emulsions and macro emulsions.
Emulsions made with WACKER® AF 3670 are diluted to the optimum concentration for the specific fabric. Application can be done by padding or exhaustion. WACKER® AF 3670 can be utilized as the active substance in softener emulsions or in combination with other components, e.g. paraffin waxes, organic softeners, etc. Compatibility of the components has to be checked in each individual case.
