WACKER^® FINISH WR 215 LV

WACKER^® FINISH WR 215 LV is suitable for the formulation of micro emulsions and macro emulsions. WACKER^® FINISH WR 215 LV 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. When applied under normal conditions as part of a softener formulation, WACKER^® FINISH WR 215 LV has no effect on the whiteness. In fact, it has no perceptible influence on the color or color fastness of textiles and fibers in general.

Processing: 

WACKER^® FINISH WR 215 LV 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^® FINISH WR 215 LV is mainly applied from emulsion. Emulsions prepared of WACKER^® FINISH WR 215 LV are diluted to the optimum concentration for the specific fabric. Application can be done either by padding or exhaustion method.

Typical formulation
7.0 parts i-tridecyl-O-(EO)5-H (HLB 11)
5.0 parts i-tridecyl-O-(EO)8-H (HLB 13)
3.0 parts polyethylene glycol 400 (PEG 400)
12.0 parts demineralized water
20.0 parts WACKER^® FINISH WR 215 LV
52.78 parts demineralized water
0.12 % acetic acid 80%
0.1 parts preservative

For emulsion manufacturing slow shear mixers are sufficient (e.g. blade, anchor, propeller, etc.).
Add the emulsifiers to the demineralized water and thoroughly homogenize. Slowly add WACKER^® FINISH WR 215 LV and stir until the product is homogeneous. Finally dilute with demin. water, add the acetic acid and the preservative. The first milky emulsion then clarifies. Filter the emulsion through a fine Perlon fabric.
