Hello,
I am new to composites. I have started with few sets from Easy Composites.
I made a few tests on plexiglass and unfortunately I do not get a glossy surface on the carbon plate. In addition after 24hrs the resin did not fully cure and the plates are a bit soft
Please see the pictures.
I applied Easy Release Agent 2 times. 1 application and then after 5 minutes the second one. The ration resin to hardener was 100:30. (Slow)
Can you please advice
1) What can be wrong?
2) How many applications should I do with Easy Release and what should be the time in between?
Thank you!

Hello. I mixed 100:30, 70 grams of resin and 21 gram of hardener. The temperature was around 18C.

Also there is a lot of pinholes which suggests not enough resin went in or you sucked too much out which is easy to do on small pieces. For best cosmetic results we recommend leaving the resin feed.....

HI Waren. I closed the resin feed and waited for 5 min until the air is sucked by the pump.

Mixing ratio looks fine, although it is a small batch for an infusion. Check the accuracy of your scales. Temperature is a little low but should still cure. You shut the ports the wrong way round......

if you did not degas the resin in a vacuum chamber before the infusion, this will cause the pinholes, you were asking about. you basically degas the resin under the film, and without any flow, the ai...
