- Safety Note
During vulcanization methylethylketoxime is released. These vapors should not be inhaled for long periods or in high concentration. Hence, good ventilation of the work place is necessary. Should uncured silicone rubber come into contact with eyes or mucous membranes, the affected area must be rinsed thoroughly with water as irritation will otherwise be caused. Avoid prolonged contact of uncured sealant with the skin, use a dry cloth or paper to remove it.; Keep out of reach of children.; Cured silicone rubber, however, can be handled without any risk to health.
