Safety & Health

Safety Notes

Thermal Stability

Provided that moisture is excluded and heating time is short, decomposition only occurs at temperatures greater than 300°C. Exposure to moisture results in decomposition at much lower temperatures, expecially in the case of thin layers. Hydrogen is liberated during this process and an increase in viscosity and/or gelling is observed. In the precence of specific catalysts (e.g. organotitanium compounds), ELASTOSIL® CROSSLINKER 525 can undergo thermal depolymerization with liberation of volatile, hydrogen-containing silanes and siloxanes.

Reactivity, dangers

In the presence of specific catalysts (acids, amines, metals, metal salts, platinum catalysts), ELASTOSIL® CROSSLINKER 525 may react with water, alcohols and similar strong proton donors to liberate hydrogen. The reaction maybe particularly vigorous in the presence of traces of alkaline substances in the homogeneous mixture. Direct contact between ELASTOSIL® CROSSLINKER 525 and alkalies should be avoided at all costs. The same applies to strong oxidizing agents.
