Examples of applications by padding
When used alone, BLUESIL EMUL 21837 should be diluted with cold water. The
concentration of the padding liquid should be adjusted to give a pick-up of
0.2 - 2.0 % silicone solids on weight of fabric. The exact level required will depend upon
the type of fabric and the level of softening effect required. The fabric should be dried
and cured at temperatures in excess of 80 °C.
Very dilute mixtures of the product should be stored for no longer then 48 hours at
ambient conditions. When used with organic softening agents or other finishing
chemicals the compatibility of the system should be pre-checked prior to bulk use.
Although BLUESIL EMUL 21837 is compatible with most organic softeners and
chemicals the emulsion stability may be affected under extreme conditions.

Examples of applications by exhaustion
As BLUESIL EMUL 21837 is shearing stable it is suitable for use from a range of
dyeing equipment. Any equipment suitable for exhaustion dyeing will also be suitable
for BLUESIL EMUL 21837 application.
A final level of 0. 2 - 2.0 % silicone solids on weight of fabric will give an excellent
handle and optimum levels will depend upon fabric type and required softness.
The pH of the bath should be adjusted to 3.0 - 5.0 and the temperature rose to 50 °C
prior to addition of BLUESIL EMUL 21837. The BLUESIL EMUL 21837 should then be
added and the temperature held at this level for 45 - 60 minutes when exhaustion takes
places. The bath should now be dropped and the fabric hydroextracted prior to drying /
curing at a suitable temperature above 80 °C (see padding information).

BLUESIL EMUL 21837 may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL EMUL 21837 is a high activity emulsion of an amino functional silicone. When applied to textile fabric an elastomeric silicone finish is produced which gives an excellent soft handles and stabilisation to the structure of the fabric.
