Hi Everyone.,

I degassed the PDMS for 1 hr using vacuum dessicator .

I immediately cured the PDMS at same 120 degree
celcius., no bubbles were found.

When I repeated the same after 30 minutes after
degassing, lot of bubbles got introduced.

Whether PDMS again absorbs the air (from atmosphere)
after degassing????

Regards
