Temp.:
40 °C

Any other information on results incl. tables

surface tension of tetramethylene diamine is 0.033354 N/m. The surface tension is relevant in case the viscosity triggers an asperation hazard.

Applicant's summary and conclusion

Conclusions:
Surface tension of tetramethylene diamine is 0.033354 N/m (=33,3 mN/m).

the criterium for aspiration hazard is 29mN/m, with the test result being higher it can be concluded that there is no aspiration hazard based on this test result.
