ELASTOSIL® E70 is a flowable, one-component, acetoxy-cure silicone rubber that cures at room temperature under the influence of atmospheric moisture. It shows excellent primerless adhesion to many substrates and outstanding heat stability even in long-term exposure. It is a high-temperature-resistant grade for sealing and bonding applications under high thermal stress.

Safety & Health

Safety Notes

During vulcanization of ELASTOSIL® E70, a total of 3% by weight of acetic acid 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.
