Description of key information

It can be concluded by expert judgement that HDI Trimer asym. does not 
- ignite spontaneously with water
- liberate flammable gases in hazardous amounts

Key value for chemical safety assessment

non flammable

Additional information

The structural formulas of the components contain none of the functional groups quoted in Manual of Tests and Criteria (fourth revised edition, appendix 6, article 5.3) which may react with water to emit flammable gases. Additionally, based on the flash point, no classification for the hazard of flammability is required.

Justification for classification or non-classification

HDI oligomers, iminooxadiazindione is not yet classified in the Annex I of Directive 67/548/EEC. According to the information summarized in this below, no classification on flammability is needed:

- As liquid, no flash point up to 249 °C;

- As liquid, boiling point is higher than 300 °C;

- No pyrophoric property, based on experience from production and handling;

- It does not ignite spontaneously with water and does not liberate flammable gases in hazardous amounts in contact with water.

Based on the data summarized above, HDI oligomers, iminooxadiazindione is also not flammable according to GHS (Regulation EC 1272/2008).
