Static

This may only be a problem in dry climates. I'm in Melbourne Australia, granted not the driest part of the country, but dry nonetheless.

Once Airid completes the drying process the resin is so charged with static that when I take the lid off it goes everywhere. Pouring it out into the bags for vacuum sealing it sticks to the inside of the jug and is quite loath to go where I want it. I'm not sure if there's a way to earth it so that it behaves better!

Hi @poida,

Apologies for the late response, I hope all is well.

The dry climate in Australia actually makes the drying process more effective! But indeed the side-effect of this is the electrostatic charge, since usually moisture serves as a conductor to help release the static charge. Letting the material cool down decreases this effect, so perhaps letting it sit in the dryer for a while helps!

In the polymer industry they often make use of certain 'surfactant' additives to prevent this issue, but this might overcomplicate the process a bit :).

Best regards,

Timo
