Hi everyone,i skin parts for automotive interiors with cf using the ec high temp epoxy resin,after the wrapping i wet the fabric with epoxy,after 24hours i sand with 120grit and after that add 2 layers of epoxy when the first is at tack free stage.
After that i put the parts in an oven and ramp the temp at 100celcius,after that i have too much amine blush,it can stick to my hand,is this normal?
Is there any chance  the epoxy to keep blushing under the 2k clearcoat and give me a yellowish pary?
I must wait more time to cure after the complete cycle at the oven?

What can cause the 'yellowish' of the carbon skinned glovebox ?this epoxy is easycomposites high temp epoxy,post cured at 90celcius,carefully remove the amine blushand then 2k clearcoated
The other parts are skinned with other epoxy resin
And they are  cleared with the same 2kclearcoat

the glovebox is new and never see the sunlight,the other parts are 1year old under the hot greek sun
