Low M.W. PTFE Aqueous Dispersion
SFN-D is a low molecular weight aqueous
dispersion of PTFE. In addition to superior properties typical of PTFE dispersions, SFN-D
features low viscosity, good flow performance, and excellent penetration. It can be used
along, or be added as an aid into other ordinary PTFE aqueous dispersions, such as PTFE Aqueous Dispersion SFN-1 .
Adding SFN-D at 3 - 5 % by weight
into SFN-1, for instance, can offer
such advantages to coatings as enhanced bonding to base substance, thicker layer with each
pass of coating, more glossy and void-free surface, greater resistance to wear and
SFN-D is usually used as an aid to ordinary PTFE dispersions for the applications of impregnating fabric, porous
materials and coating metals by processing methods of dip, coating, and spay coating.

Packaging, storage and transportation:
- Packaging: 25 kgs net in plastic drum.
- Store SFN-D at clean dry place with
temperature 10oC ~30oC. Keep away from sunlight. It
is recommended to shake the dispersion in container slightly every 15 days during storage,
and do it also right before using.
- Transport SFN-D as
non-hazardous chemical. Keep away from sunlight and rain.
life: one year since production. When exceeding the shelf life, the product could
still be used as long as it is re-tested and approved.
precautions for handling
and use SFN-D only in well ventilated areas
not smoke when using or processing SFN-D.
