BLUESIL FLD 21645 is a medium to high viscosity amino functionalized polydimethylsiloxane, based on our patented HALS (Hindered Amine Light Stabilizing) technology.


Functional Fluid

​BLUESIL FLD 21645 has been developed for formulation into emulsions destined for use in textile applications.

When applied to textiles it imparts properties of a good compromise between softness and hydrophilicity, whilst remaining non-yellowing due to the presence of HALS groups.​

​BLUESIL FLD 21645 is easily emulsified into micro- or macro-emulsions, using typically C13 [EO]6 alcohol ethoxylated surfactants.

The application onto textile surfaces imparts the following properties:

  • Non-yellowing even at high temperatures.
  • Very good soft handle.
  • Good compromise softness / hydrophilicity.
