Description of key information
A read across from Zinc methacrylate has been performed in order to determine the dust explosivity of hydroxy(2-methylprop-2-enoato-O)zinc.
As the particle size of Zinc methacrylate is very close to that of hydroxy(2-methylprop-2-enoato-O)zinc, we could conclude that the result should be also positive. In the study of zinc methacrylate, the measured overpressure relative to the initial pressure (pm) is in three tests significantly above 0.3Zinc methacrylate has been identified as dust explosible and therefore hydroxy(2-methylprop-2-enoato-O)zinc could be considered also as dust explosive.
Additional information
A read across from Zinc methacrylate has been performed in order to determine the dust explosivity of hydroxy(2-methylprop-2-enoato-O)zinc.
As the particle size of Zinc methacrylate is very close to that of hydroxy(2-methylprop-2-enoato-O)zinc, we could conclude that the result should be also positive.
In the study of zinc methacrylate, the measured overpressure relative to the initial pressure (pm) is in three tests significantly above 0.3. Zinc methacrylate has been identified as dust explosible and therefore hydroxy(2-methylprop-2-enoato-O)zinc could be considered also as dust explosive.
Additionals data explosion were performed for the zinc methacrylate to measure:
-Maximum Explosion Pressure (Pmax): 7.4 bar
-Max.Rate of pressure Rise (dP/dt)max: 519 bar/s
-Kst value: 141 bar.m/s : The relationship between Kst value and the physical severity of the dust explosion is weak explosion
-Minimum Ignition Energy:10-25mJ
