It has been specially designed for the manufacture of carbon parts in closed mould, but can be also used for hand lay-up applications, taking into account that some sagging could be suffered. To avoid it you can add some thixotropic agent to the resin prior application.
The 1kg and 5k cans are supplied accelerated. If the customer wishes, the 25kg drums can be supplied without accelerating.
