Characteristics
WACKER AM-9 is an aminoethyl-aminopropyl functional polydimethylsiloxane.

Applications
WACKER AM-9 is particularly suitable as active substance in softener formulations for the impregnation of fibers and textiles. WACKER AM-9 imparts a very soft, drapable, and elastic handle to woven and knitted fabrics. WACKER AM-9 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 AM-9 has 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 colour fastness properties of coloured goods is observed.


On woolen fabrics and knit ware WACKER AM-9 contributes to a reduction of shrinkage due to it´s high affinity to the substrate. As part of formulations used as fill fibre finish WACKER AM-9 imparts excellent slickness and resilience to the fibre.


Processing
WACKER AM-9 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 waterbased. Hence WACKER AM-9 is mainly applied from emulsion. WACKER AM-9 is suitable for the formulation of microemulsions and macroemulsions.

WACKER AM-9 can be use as sole active substance in softener emulsions or in combination with other components, e.g. paraffines, esters of fatty acids, etc. Compatability of the components has to be checked in each individual case.


Emulsions of WACKER AM-9 are diluted to the optimum concentration for the specific fabric. Application can be done by padding or exhaustion.
