Outstanding purity, high binding efficiency and excellent rheological control, low lehring temperature

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.

Our Solutions

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
