Thread: Epoxy removeal

Hi Guy's,

I've been looking on line but thought I'd ask here as there's lots of clever bugga's around!
I need a way to remove epoxy (not sure what type) that was used for mounting bases on an alloy receiver.
The receiver is black, probably anodized and I don't want to mark it.

Cheers

if its araldite etc, get it hot and then wipe it off with a cloth with acetone on it.

And keep the hot source away from the acetone or you'll remove your eyebrows

It's a Browning Maral. Nothing near the bases (already removed), I just don't want anything unsightly/damaging. The bases were horrible alloy ones and I want something a little more in keeping with the look.

Gentle heat will soften it but be really carefull of the anodising. If its Araldite it should come off ok if you go slow and use the acetone rag as well.

adjustable heat gun is the thing, take it up a bit at a time till it softens . . .

Bunnings sell an adjustable heat gun for $40.

Why not use heat on aluminium? Most of the the epoxies soften at about 50C. In the past I've used aluminium pots and pans to cook with and even melt lead in. It is also used in vehicle radiators that are designed to cope with water above 100C entering them, the anti boil and pressure cap are there to keep raise the boiling temperature.

If you are worried about heat warping, heat the whole piece in an oven, 50-60 deg C will plasticise most quickset epoxies.

Yep the oven technique works great.
Her In Doors didn't appreciate finding Indian & Norton engine and gearbox bits in it or the dishwasher though!

Dishwasher what a great way of degreasing and cleaning engine parts!

What a freaking good idea !!!!

Acetone and heat dont mix that stuff is highly flamable
