WACKER® HC 621
WACKER® HC 621 is an finely dispersed water-based silicone emulsion. The particle size is in the nanometer range.
WACKER® HC 621 can be easily diluted with water or readily incorporated into coldstirred formulations.
WACKER® HC 621 is manufactured to have a low content of low molecular weight cyclic siloxanes (i.e. D4,..., D8 <500 ppm)
WACKER® HC 621 is used primarily as polish in the home care sector.
WACKER® HC 621 is ideal for impregnating natural or synthetic textiles in a washing machine. It is recommended to apply the product in the rinse cycle. The impregnation effect is reached without loss of breathability of the fabrics. Recommended application concentration: 100 g WACKER® HC 621 / rinse cycle
Besides WACKER® HC 621 is well suited for hydrophobing most different materials as textiles, leather, wood, cork, paper, etc. For these applicationsWACKER® HC 621 is diluted with water to an active content of 1 – 5 %.
Slightly acidic conditions (pH 4 – 5) of aqueous formulations of WACKER® HC 621 could improve their stability.
Stir well before use.
The 'Best use before end' date of each batch is shown on the product label.
