- Surface tension:
- 65.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- Bayscript Blaukompoente TEA-Salz shows a surface tension of 65.5 mN/m at 20°C at a concentration of 1g/l.
- Executive summary:
The surface tension of Bayscript Blaukomponente TEA-Salz was investigated according to EC Test Procedure A.5 and DIN EN 14370 by the ring method. The test was performed at 20°C and a test item concentration of 1g/L in the aqueous test solution. A surface tension of 65.5 mN/m was determined (BTS 2017).
Reference
The concentration of the test item in water was 0.1%. Double distilled water was used for preparing the solution. The temperature of the soulution at the time of the test was 20°C. The solution was tempered over night, the preperation time for the solution was about 25 minutes. The calculation of the surface tension was done automatically under consideration of the correction of the test equipment and according to Zuidema and Walters by the measuring device.
