Good morning

When I used to work in a composite shop we used to use silicone rubber 2 part mix for making insert/formers that we would make to make shapes by adding the soft mix (plasticine texture) to the awkward parts of a mould let it set to a flexible rubber state and use it as infill pads/inserts ON TOP OF the prepreg carbon during the Autoclave curing process to help prevent bridging in awkward spaces and with it being a type of silicone it didn't stick to the resin and it was easy to remove afterwards and was reusable.

Do you have a product like this that does not need curing with temperature that I could use  as a reusable insert with wet layup carbon and your EL2 epoxy laminating resin and no vacuum .

Regards

Yep that sounds like the stuff and the cost of it, hence why we were told to use it sparingly. Can you remember the name of it by chance? I can do some digging about and see if theres a cheaper option from tygavac? they are in work tomorrow so I can ask them then.
