Composite molding
- Application Details
- 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.
Processing
- 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.
- Only components A and B with the same lot number may be processed together.

Safety & Health
- Safety Note
Components A and B of the addition-curing grade ELASTOSIL® C 1200 A/B contain only constituents that over many years have proved to be neither toxic nor aggressive. Special handling precautions are therefore not required, i.e., only the general industrial hygiene regulations apply.
