BLUESIL ESA 7241 A&B can be applied using a two-component dispenser with a 1 : 1 mixing ratio. In the case of manual mixing, degas under vacuum conditions (3-5 kPa) before use.

At room temperature, the pot life of the mixed product is approximately 16 hours.

Curing of BLUESIL ESA 7241 A&B takes place at a temperature of between 100°C and 200°C. As an indication, the curing time at 150°C is approximately 10 minutes.

The curing reaction can be inhibited by contact with substances containing Sulphur, amines and metal salts.

BLUESIL ESA 7241 B may be stored at temperatures between -20°C / -4°F and 30°C / 86°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL ESA 7241 A&B is a liquid two-component, polyaddition heat curing silicone elastomer.

After polymerization BLUESIL ESA 7241 A&B forms a flexible adhesive film or gasket which is particularly resistant to thermal, climatic and environmental attack.
