10. Stability and reactivity
10.0 General information: no dangerous reactions known when stored and handled properly.
10.2 Substances to avoid: reacts with water/humidity with formation of acetic acid.
10.3 Hazardous decomposition products: none known when stored and handled as prescribed.

11. Toxicological information
11.1 Acute toxicity: after reaction, vulcanizates are neither mutagenic, carcinogenic nor teratogenic and present no hazard for people and the environment.
11.4 Other toxicological information: product eliminates small amounts of acetic acid during polymerization. This can irritate the skin and mucous membranes.

12. Ecological information
12.3 Ecotoxic effects: silicone rubber is not biologically degradable, easy to separate from water mechanically.
12.4 Other ecological information: do not empty into bodies of water/drain. Vulcanizate is insoluble in water.
