Safety notes
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from WACKER subsidiaries.
During vulcanization methanol and ethanol are released. These vapours should not be inhaled for long periods or in high concentration. Hence, good ventilation of the workplace 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.
