9,9-Bis-(4-amino-3-chlorophenyl)-fluorene
Chlorophenyl Amino Fluorene (CAF) is a highly specialized amine-hardener for various applications. The two primary amine-groups react readily with e.g. gylcidyl-moieties of epoxy resins, resulting in cured epoxy-matrices of outstanding electronical properties.
Applications
- CAF is mostly used as a hardener in electronic applications
- Printed circuits, capacitors, circuit boards: CAF-hardened epoxy layers show a much lower water adsorption tendency, compared to conventional polyamine-hardeners
- Capacitors from epoxy and dispersed metal oxides: using CAF, the resulting capacitor layers show a much lower electrical dissipation and leakage
- Allover, CAF-cured epoxy-coatings show a very low tendency for pick-off when used in coil-coating applications
CAF can be advantageous when used in the production of prepregs
- Melt-dissolved CAF acts as a latent hardener
- Good tack at room temperature (21-25 °C)
- Longer shelf life, easier processability
- Outstanding water-resistance after curing
CAF shows positive impact on the mechanical and electronic properties of hybrid polyolefine-glycidlyacrylate-hotmelts when used as crosslinker.
CAF can be used as a monomer to produce polyimide-fluorocarbon-blends
- Resulting resins show low dielectric constant
- Very good processability
- As insulator for high-frequency electronics
Shelf Life
Under proper storage conditions, the shelf life is 12 months
