4. Data
【1.Comparison in spectroscopic reflection ratio with epoxy-resistant materials】
* These data on epoxy-resistant materials are reference data estimated based on literature and catalogues.
【2. Results of heat-resistance tests (150℃ x 1000h)】
* Measurement conditions and measurement devices were provided by Shimadzu Corporation.
Spectrophotometer (UV-31 50 BaSO4) Test specimen (t=100μm) was measured assuming
white sheet to be 100.
