Applications by padding
When used alone, BLUESIL EMUL 21839 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 pH of the bath should be adjusted below 5.5.
The fabric should be dried and cured at temperatures in excess of 80°C, however temperatures of 150ºC are recommended. The full softening effect is manifested after adequate fabric conditioning at atmospheric conditions.
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.
Application by exhaustion
Any equipment suitable for exhaustion dyeing will also be suitable for BLUESIL EMUL 21839 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 risen to 50°C prior to addition of BLUESIL EMUL 21839.
The BLUESIL EMUL 21839 should then be added and the temperature held at this level for 45 - 60 minutes when exhaustion takes places. The fabric should be dried and cured.
