A non-ionic polyester-polyurethane film former published for a soft coating on the fiber with excellent strand integrity and good solubility in styrene. 35.2 percent solids, 400 nanometer particles, for continuous or chopped glass, carbon, basalt and mineral fiber going into nylon, polycarbonate and polyurethane.
FILCO 8000 is a waterborne non-ionic polyester-polyurethane dispersion used as a film former in sizings for continuous or chopped glass, carbon, basalt and mineral fibers. COIM publishes it at 35.2 percent solids with an average particle size of 400 nanometers and a Brookfield viscosity of 50 mPa s.
COIM's stated characteristics are a soft coating on the fiber and excellent strand integrity, which is the combination a line wants when the strand has to hold together through handling without the tow going stiff. The film has good solubility in styrene, so it also suits unsaturated polyester work where the size should dissolve into the resin.
The non-ionic dispersion gives superior stability at very acid or very basic bath pH, and COIM publishes wide compatibility with typical sizing additives. The matrix side is nylon, polycarbonate and polyurethane.
COIM publishes no dried-film mechanical data for this grade. For a published stiffness number, the soft reference is FILCO 547 at 2 MPa, and the anionic grades D2496, D2596, D2594 and D2476 run from 8 to 20 MPa.
It is also written as FILCO F8000, F8000, 8000 sizing, non-ionic polyurethane dispersion, polyester polyurethane film former, and strand integrity film former.

Typical values from the manufacturer's technical data sheet. They describe the product, they are not a specification. We will send the current TDS and the batch documentation your qualification needs.
Tell us the binder system, the property you are targeting, and the volume you expect. We will confirm the grade, send the documentation, and get a sample of the candidate grade to you.
Published for excellent strand integrity with a soft coating, so the strand stays together without the tow stiffening.
High compatibility with those matrices, where an epoxy film former does not couple.
Good solubility in styrene, so the film dissolves into the laminating resin rather than sitting at the interface.
Non-ionic stabilization holds where an anionic dispersion would not.
Wide compatibility with typical sizing additives.
It is specified where the formulation needs soft coating with excellent strand integrity, both stated by COIM, non-ionic, stable in very acid or very basic size baths, good solubility in styrene, fine 400 nanometer particle size for filaments a few microns across, and hydrazine-free, as marked in COIM's published range.
Applied at the fiber line or in a re-sizing bath. The low viscosity at 35.2 percent solids dilutes readily into a bath.
Where the strand has to hold together through winding, conveying and chopping but the tow must stay soft, this is the grade COIM's own characteristics describe. Where a compact, stiff bundle is the goal, move to the anionic grades with published modulus.
The film is thermoplastic and non-reactive. Where the process should crosslink the film, look at the reactive polyurethane family instead.
Package sizes: Made to order in the pack size the line needs. Tell us the volume and we will confirm..
Storage: Store in closed containers away from direct sun at 41 to 86 degrees F. Maximum suggested storage is 12 months from production in the original package, after which the product must be rechecked. Freezing destroys the dispersion permanently.
Not classified as dangerous under Regulation EC 1272/2008 (CLP) and not regulated for transport. Read the safety data sheet before handling. We supply the current SDS with every shipment in the manufacturer's current revision.
A soft coating on the fiber with excellent strand integrity, on continuous or chopped glass, carbon, basalt and mineral fiber, for nylon, polycarbonate and polyurethane matrices. COIM also publishes good solubility in styrene and wide compatibility with sizing additives.
Both are non-ionic polyester-polyurethanes for the same fibers and matrices. FILCO 547 runs at 45 percent solids and carries published dried-film data, 2 MPa modulus at 650 percent elongation. FILCO 8000 runs at 35.2 percent solids and 400 nanometers and is published for strand integrity and styrene solubility rather than a film stiffness number.
COIM does not publish dried-film mechanical data for FILCO 8000. Its characteristics are stated as a soft coating. If your selection needs a modulus number, FILCO 547 and the anionic grades D2496, D2596, D2594 and D2476 all carry ASTM D1708 data.
Yes. The data sheet names continuous or chopped glass, carbon, basalt and mineral fibers.
Yes. Tell us the fiber, the matrix and the process, and we will send the current technical data sheet with the matching safety data sheet and arrange sample material for the trial.
Yes. We send the Technical Data Sheet (TDS) and Safety Data Sheet (SDS) on request, in the manufacturer's current revision. Use Request TDS or SDS above and tell us what your qualification review needs.
