Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Lobbes 2010: Melting point/freezing point, OECD 102, EU A.1: Melting range >63 to <72 °C
QSAR, Wenighofer 2009: The melting points were calculated for the main components of Resin 835 A:
- Dehydroabietic acid, CAS No. 1740-19-8, 54 % (w/w) of Resin 835 A: 160 °C
- Dihydroabietic acid, CAS No. 19407-37-5, 25 % (w/w) of Resin 835 A: 147 °C
- Pimaric acid, CAS No. 127-27-5, 4 % (w/w) of Resin 835 A: 154 °C
- Isopimaric acid, CAS No. 5835-26-7, 3 % (w/w) of Resin 835 A: 154 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
63 °C

Additional information

The melting range was determined via Differential Scanning Calorimetry (DSC) and Thermo Mechanical Analysis (TMA) and was >63 and <72 °C.
