Hi there

I’m not having a lot of success degassing P6 two part resin.. is there a particular negative pressure I need to achieve?

I’m wondering if the pump I’m using hasn’t got enough oomph!

Though it works fine for the silicon mould making part of the process?

Your thoughts would be appreciated!

Thanks

Ben

You can predegas both components before mixing for a long period of time. This will remove any moisture that the resin and hardener has absorb after it has been opened. This will also help your potlife be more stable as moisture will make your resin kick faster.
