View Full Version : Does Silicone Grease Freeze?

Hi Guys.
A simple enough question (Hopefully!)
I have a modern coldstore with standard Thermod doors which have a large pull handle on the outside and large semi circular push pads on the inside.
The internal push pad is connected to the door release mechanism via a solid plastic rod.
Which slides within a plastic guide tube.
Over time the slide action becomes compromised by the build up of ice within the door.
With the door becoming harder and harder to open.

Historically I have stripped the Mechanism, cleared and dried the tube and rod.
But eventually the build up and restriction is repeated.

I was just wondering if I were to lubricate the 2 parts with Silicone Grease, whether it would stop the parts freezing up?
What do people think?

Data sheet for a grease from Farnel shows -50°C

One drawback is that nylon absorbs water over time which doesn't help the situation.

We used to use silicone grease to lubricate sliding doors on self serve coffin style freezers, magic stuff:))
