- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16/01/2012
- Reliability:
- 2 (reliable with restrictions)

- no guideline followed
- Principles of method if other than guideline:
- A particle size (PS) distribution of F-2200 LOT # 290110772 was measured using Mastersizer 2000 (Malvern Instruments). 1 gr. sample was added to 10 ml of 4% Sodium Dodecyl Sulphate aqueous solution. A suspension obtained was added to water and then sonicated for 3min.

- no
- Type of method:
- other: see above
- Remarks:
- see above
- Type of distribution:
- volumetric distribution
- Key result

Description of key information
Brominated Epoxy having Epoxy Equivalent of 400 gr/eq PSD
Additional information
Brominated Epoxy having Epoxy Equivalent of 400 gr/eq is an oligomeric mixture. Hence, the substance appearance is composition depended. A typical composition forms a light-yellow viscous waxy solid with unidentified particles. A substance composition containing 92% of the n=0 component (F-2200) is a solid with identified particles which exhibit the following PSD:
10% of the volume distribution is below D 10 = 10.9 µm,
50% of the volume distribution is below D 50 = 128.2 µm
90% of the volume distribution is below D 90 = 508.4 µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
