Hi,

I would like to Know if there´s a faster method to check OH number of a polyester resin than the pyridine´s method (that takes 1 hours to be completed).

Thank you very much,

Rodrigo Toledo

RE: OH Number

We use both the volumetric and coulometric analysis on polymers.  It has been somewhat automated by using instruments from Mettler.
