Safety & Health
- Safety Notes
During vulcanization of ELASTOSIL® A234 WHITE, a total of 3% by weight of an amine is split off. These vapors should not be inhaled for long periods or in high concentration. Work areas should therefore be well ventilated. Contact of unvulcanized silicone rubber with eyes and mucous membranes must be avoided as this would cause irritation. However if it does happen, rinse the affected area thoroughly with water.
