Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
not specified
Principles of method if other than guideline:
Many liquid acrylate resins solidify in an amorphous glassy structure upon cooling. Whence, reactive resins often show a glass transition rather than a melting behavior. Exceptionally, melting can be observed. Since the resins are liquid at room temperature, the glass transition/melting is measured at sub ambient temperatures using conventional differential scanning calorimetry (DSC).
GLP compliance:
no
Type of method:
other: DSC (differential scanning calorimetry)

Applicant's summary and conclusion

Conclusions:
Many liquid acrylate resins solidify in an amorphous glassy structure upon cooling. Whence, reactive resins often show a glass transition rather than a melting behavior. Exceptionally, melting can be observed. Since the resins are liquid at room temperature, the glass transition/melting is measured at sub ambient temperatures using conventional differential scanning calorimetry (DSC). The melting point/glass transition temperature of Propylidynetrimethanol, propoxylated, esters with acrylic acid is -61C.
Executive summary:

The melting point/glass transition temperature of Propylidynetrimethanol, propoxylated, esters with acrylic acid is -61C.
