Remark: Measurement of Viscosity

1 Solution Viscosity was determined in 5% by weight in 95% ethanol, at 20℃, using Brookfield viscometer.
2 Solution Viscosity was determined in 10% by weight in at 20℃, toluene/ethanol 1/1, using Brookfield viscometer.
3 Solution Viscosity was determined in 5% by weight in toluene/ethanol 1/1, at 20℃, using Brookfield viscometer.


Major applications:

  1. Copper foil laminates: Binder for copper foil and Epoxy laminates
  2. Printed circuit board bonding adhesives
