Lighting

It seems as though every light bulb in every house is being changed from the incandescent bulb to the highly efficient CFL bulb. Phosphor coatings are used when manufacturing fluorescent lamps. Incorporating POLYOX™ and/or ETHOCEL™ as binders in the phosphor coating means clean burn-out, rheological control, and stability across a wide range of pH values.

In the fluorescent lamp manufacturing process sacrificial binders play a crucial role allowing tailoring the rheology of the phosphor coating. Those binders need to provide high binding efficiency, excellent solubility and rheological control combined with high purity and a low lehring temperature.

POLYOX™ water-soluble polymers and ETHOCEL™ ethylcellulose polymers are ideal binders for phosphor coatings in the manufacture of fluorescent lamps. Both products offer high binding efficiency and excellent rheological control.

When POLYOX™ is used as a binding agent, it offers:

  • Water-solubility
  • Compatibility with a variety of dispersants and antifoams
  • Stability across a wide range of pH values
  • Efficient rheological control
  • Low lehring temperature
  • Clean burn-out
  • Low emissions

ETHOCEL™ product line offers high efficiency binders that provide:

  • Solvent compatibility
  • Efficient rheological control
  • Clean burn-out
  • Compatibility with a variety of dispersants and antifoams
  • Stability across a wide range of pH values


POLYOX™ water-soluble polymers are broadly used as binders for the aqueous phosphor coating formulations used for fluorescent lamp manufacturing.

ETHOCEL™ ethylcellulose polymers are being widely used in organic-solvent based fluorescent lamp formulations.
