Description of key information

Flash Point (3-chloropropyl)dimethoxymethylsilane: 41 - 70°C (DIN 51758, ISO 3679)

Key value for chemical safety assessment

Additional information

Several measured flash points are available. Those known to have been conducted according to international or national standard methods are considered reliable, even where no further information about the studies is available. The reliable values are 41, 46, 57, 57.5, 67 and 70°C.

Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. In particular, the presence of higher concentrations of volatile impurities such as methanol; a hydrolysis product of the substance, can result in lower flash points. The reliable values are taken as part of a weight of evidence approach. Individual companies will classify their products according to the flash point data specific to their substance.

Flash points of 41, 46, 57 and 57.5°C indicate the substance is flammable; flash points of 67 and 70°C indicate that the substance is not flammable according to the criteria of Regulation 1272/2008/EC.
