Description of key information

The vapour pressures zinc methacrylate at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 7.84 * 10-06 Pa and at 25°C: 1.22 * 10-05 Pa

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

Key study was performed in order to determine the vapour pressure of zinc methacrylate according to the OECD 104 and the EU method A.4.

Experiments 1 - 5 (nominal temperatures 30, 45, 60, 75, and 90 °C) showed no significant and/or reproducible weight loss. Experiments of Three temperatures ( 105,120,135) could be evaluated as they showed significant and reproducible weight loss. All measured values of the evaluated experiments showed medium reproducibility caused as only minimal weight losses were measured, giving relative standard deviations of less than 40 %. For the test item zinc methacrylate, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation: Vapour pressure at 20 °C: 7.84 * 10-06 Pa and at 25°C: 1.22 * 10-05 Pa.

This study was considered as reliable without restriction because the test was performed in compliance with OECD and EU guidelines giving scientifically valid results.
