Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The surface tension of Epoxy half acrylate was determined according to OECD guideline 115 using the plate method. Three measurement series were performed. Surface tension in the three experiments showed a variation (100% -min/max) of 6.5%. In the first measurement series, the mean values (61.46 mN/m) lay above the threshold for surface tension. In the second and third series, mean values of 59.01 and 57.47 mN/m, respectively, were recorded; both lying below the threshold for surface tension. Variation between second and third series was below 3%, indicating that equilibrium had been reached. As the determined surface tension of Epoxy half acrylate was lower than 60 mN/m in equilibrium, the test item should be classified assurface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
