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: - Copper foil laminates: Binder for copper foil and Epoxy laminates
- Printed circuit board bonding adhesives
