I would like yo know all of your opinions about degas process.
Should I need to do it every time before infusion ?
From my experience, I will have a surface problem when I do a big size part(more than 2sqm)without degas, but for smaller the surface is quite fine. I’m not sure whether this problem occur because degas or other causes.
My resin degasses by its self. Not sure why… I use a VE resin. After I mix it it foams a little, but all the air releases on its own. Or so I think? The resin is quite translucent so I’m able to see if its free of air bubbles.
1st: Always degas if you make an infusion!
I wonder that you have the problem at bigger parts. Normal the resin will degas better in the process than bigger the part is.
If you degas your resin you will wonder how much air is in the resin, even if you can not see any air in the resin. In vacuum the air will expand up to 1000 times as big, and than even a small bubble will become big.
Maybe you should read the MTI thread, there is nearly everything written dorwm you should know about infusion and degassing.
2tall: what you are seeing is the styrene reacting with other things, or even the cobalt and trig/MEKP reaction. Our VER does that, but it is not degassing itself!
The foaming is a reaction of the vinylester with the H202 in the peroxide. There are H202 free peroxides.
where is this MTI thread…?
