Injection acrylic using cold cure material

[lcmlabforum]

Maybe someone like Pat Coons or Bob Kreyer can chime in.
My understanding is injection systems need to used PMMA designed to be injected.
A cold cure/autopolymerising resin may be curing as you inject and have residual stresses
that can be released after full cure and divested. Or am I overthinking it.
I am not even talking about using regular heat cured resin . . .

silly question, but why inject with cold cure material?
fyi we are injecting heat cure acrylics and it works great.

Kulzer's Palajet was autocure.

About 15 years ago, a "friend" of mine, definitely not me, accidentally refilled ivocap cartridge with what "they" thought was the bulk ivocap powder and it turned out to be the ivocap repair material. Personally I would try that as my "friend" says it turned out great. I would experiment first... I think it was pro base but it was also a long time ago, but I think if you were really quick you could inject it and get it to work as a cold cure injection. That said I hear Mark J screaming at me right now after I said that...

I routinely use monoject412 syringes for this. Mix and pour immediately in. Some materials work well this way, some don't. Depends on working time and viscosity.

I believe it's hard coded to 24 hours.
