Hi,

I am new to vacuum infusion and just wondering if I need to degas my resin in a degassing chamber prior to the infusion or is letting it just sit for 5-10 at ambient air pressure enough?

Also would it be a good idea to store my resin containers in a "hot box" prior to use?

Thank you,

Erick

Hello,




I read in another post that it would help to prevent bubbles in the final part. 

That guy had problems with air bubbles in his part and stated that if you degas the resin in the pot with vacuum the result was much better or nearly perfect. Also warming up the resin and the mould would also be better.




Correct me if I'm wrong.

What JN, says is right!

The resin I ordered is the IN2 epoxy from EC I think it's shelf life is 50-60 min. How long does it take to degas in a vacuum chamber? How is degassing done?

Thanks for the help.

Hi, 

Hi Erick

I didn't find degassing helping to reduce pin holes. How I got the pinholes to stop forming was to heat my mold up untill it was quite warm to the touch and made sure the resin was also warm. When I infuse the already warm resin hits the even warmer mold and lowers the vescosity even further and it infuses very well. You must also have a perfectly sealed vacuum bag. Let the resin travel out the vacuum line for a few inches and clamp it off then wait (I wait about 15 seconds) and then clamp off the resin feed line. results, a pin hole free part. Its the heat and perfect vacuum that made the difference in my parts. Now keep in mind that you don't overheat a large mold as your resin could gell too early.

Hope this helps.

Thanks guys I appreciate the advice, I guess a little experimentation on my part is in order to see what works best for me.

i just degased at home to repair like finger size place i mixed 12 gr i thought i be dead head spining and like from space

???

Degassing Chamber is the way to go. 5-10 mins max and there will not be a single bubble in that resin. Crystal clear. Love it, definitely worth building or buying.

I built mine from an old aluminium pressure cooker, 25 mm Acrylic circular lid, vac gauge, two valves all joined by hydraulic connectors. You could use anything, but these are nice and handy cos they come in any size and type.

I will post a picture soon.

i tryed to degass and i dont get im getting small bubbles... so i dont get where im wrong.
