I am busy putting together a low cost vacuum chamber to de-air RTV silicon.
At present I am using Wacker Elastosil M4640 transparent RTV. It is extremely tacky and with the vacuum pump I am using now, I have difficulty releasing the bubbles from the RTV.
Can anybody give me a pressure rating of a vacuum pump that I will need to de-air most RTV's?
