ADVALON® CF 3295
ADVALON® CF 3295 is a ~20% solids macroemulsion finish for "PAN" carbon fiber precursor. ADVALON® CF 3295 is based on proprietary silicone technology.
Although ADVALON® CF 3295 can be used as-is, ADVALON® CF 3295 can also be easily diluted to a lower concentration using deionized water and simple mixing. Care should be taken so as to not incorporate too much air while mixing as foaming can occur. Compatibility tests should be performed before using with other chemicals. The usual method of application is via dip bath. Usual active add-on to the PAN precursor is ~1-2% on the weight of the fiber.
PAN precursor applied with ADVALON® CF 3295 exhibits good frictional behavior both from a fiber-to-metal and fiber-to-fiber perspective. Having good frictional behavior allows the fiber to be processed smoothly without damage to the PAN precursor. The antistatic behavior of ADVALON® CF 3295 also helps facilitate smooth processing by preventing loose fibers from "dancing" and becoming disoriented relative to the bulk of the fiber mass which could result in "snagging" and ultimately damage to the precursor.
