ELASTOSIL® C 1200 A/B has been especially developed for the professional production of reusable vacuum bags, used for the production of composite parts. Due to its shear thinning behavior it will be self leveling, yet not running off vertical surfaces.

It's medium term pot-life will allow the use on larger surfaces, still enabling a quick curing of the bag.

ELASTOSIL® C 1200 A/B may be processed using a manual or pneumatic gun. It is supplied in a double cartridge and will be applied directly onto the tool.

For larger amounts it may also be processed using a 2-component mixing and metering machine.

On larger surfaces it may also be sprayed using compressed air.

We recommend to post-curing the vacuum bag for 2-3 hours at operating temperature, 220 °C max.


Important note:
The platinum catalyst is in component A.

Caution:
Only components A and B with the same lot number may be processed together!
