BLUESIL FLD 21643 may be stored at temperatures between 2°C / 36°F and 40°C / 104°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL FLD 21643 is a medium to low viscosity mono-amino functionalised polydimethyl siloxane, specially developed for formulation to microemulsions (+ white emulsions) for textile softening and textile resin plasticising, where low yellowing is of major importance.


Functional Fluid

BLUESIL FLD 21643 is designed for use as a base fluid for formulation of amino silicone microemulsions + white emulsions specifically to be used as textile softeners and lubricants. It is based on a mono amine, and thus gives the ease of emulsification of oil 21637, but with lower resulting yellowness.
In application to textiles the product typically yields:

  •  Smooth soft hand
  •  Good drape characteristics
  •  Low yellowing
  •  Increased fabric elasticity and crease recovery
  •  Improved fabric tensile and tear strength
    Typical end uses include cellulosic and man-made fibres on woven, knitted and non-woven fabrics and as a lubricant in raising and sueding.
