I search an accurate method for determiantion hydroxyl value in Hydroxy acrylic resin, saturated polyester resin and alkyd resin.
Dear Botros;
this is the ASTM standard method.
ASTM E222 - 10

Dear Botros,
Determine hydroxyl value by 859 Trioterm is not possible, But possible by other instrument of Titrando - Metrohm; As followed by ASTM E 1899-08.
Other methods are available ASTM D 4274-99 or ISO : 4629.
Regards,
many thanks dears Abdelkader BOUAZIZ and Navneet Kumar
