FC128E is a water-based C8 chemical dispersion which provides a durable, non-film forming, transparent protective barrier against oil and water for synthetic fibers, as well as cotton, wool, silk, etc. It possesses prominent wash-fastness, dry-cleaning-fastness, and good compatibility with all kinds of resins, chemicals.


Typical Properties
Main component: Fluoride high-molecular copolymer
Appearance: Milky yellow liquid
Active Content wt%: Around 30
Ionic Activity: Cationic
PH g/cm3: 4.5±1.0
Spray: Can be used in consumer spray, including aerosol spray cans
Solubility and compatibility: Rather easily dissolved in water, Rather good, but preliminary test should be taken in the case of using together with other agents.

Processing
The amounts used depends on fibrous kinds, but generally, for polyester, nylon, 1.0-2.0% is applied, and for cotton, silk, 2.0-3.0% is employed. Adequate water-repellent effect is achieved by curing 150ºC∼180ºC×2min. after preliminary drying.
