Description:
SFN-1 is an aqueous dispersion of PTFE for general purposes with
properties as below
- With polymer solid content 60% (w/w),the mean particle size of the
colloidal PTFE dispersion particles is 0.05 ~0. 5 micron.
- With high stability against coagulation.
- Nontoxic at room temperature.
- Excellent chemical inertness,outstanding resistance to chemical
corrosion,such as strong acid,alkali,strong oxidant,etc.
- Outstanding resistance to heat,low temperature and abrasion.
- Can be used at temperature range from -200oC ~ +250oC for long time.
- Excellent electric insulation property,which is not affected by
temperature and frequency.
- Adhesiveless.
- No absorption of water.
- Flame-retardation,etc.
Applications:
- Be Directly used in impregnating porous materials,such as asbestos,
glass fiber,metal,ceramics and electric carbon as anti-corrosion,
sealing,anti-friction and lubricating materials.
- Be used to make protection layer by spraying or brushing on many
kinds of metal or non-metal base substances, with presence of
primers.
- Be directly used for PTFE spinning.

Packaging, storage and transportation:
- Packaging: 25 kgs net in plastic drum.
- Store SFN-1 at clean and 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-1 as non-hazardous chemical. Keep away from sunlight
and rain.
- Shelf 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.
General precautions for handling
- Store and use SFN-1 only in well ventilated areas
- Do not smoke when using or processing SFN-1.
- Avoid eye contact
- Flush immediately with plenty of water in case of contact with skin
