Plating solution contamination


#1

Will E6000 contaminate plating solutions?

The E6000 would have been used to glue a non-conductive material
onto a cast piece. Very little of the glue would be exposed, if any,
and it would be fully cured/dried.

Thanks for the help.

it seems the solution and heat would have to dissolve the epoxy. Once
cured and dried if it’s under a stone with a bezel or otherwise metal
around it seems harmless for a thin deposition as is normally
produced. I have seen plating solutions used on metallic powders
mixed into a plastic-like carrier, the result resembling metal- The
vehicle contained an epoxy resin, and PVC granules among other
ingredients- the bath was at normal operating temperatures for a
rhodium plating over a yellow gold “hamilton” plate, no problems-
just highly brittle costume jewelry resulting. I would call the
manufacturer and have the temp. you plate at available should they
have any questions. If you have to use a solvent to strip anything
first, that’s where I would be a bit concerned if the stone had not
made complete contact under the base and there is some air pocket or
otherwise a point that a solvent could go unnoticed and collect. I
believe E600 tells you on the tube safe temperatures. rer

Thanks for the input R. E.

You brought up some issues I hadn’t thought about, trapped solvent,
for example.

I will check out how heat effects E6000. Clearly it is not ideal to
have this type of material present when plating.

I suppose I could keep separate solutions for this so that if there
was a problem it wouldn’t effect everything else.

I have heard a lot about Rhodium contamination, and I am waiting
with a $50 filter if and when that happens. Not sure what to expect
in this area either.

Turns out I happened to read something yesterday about someone
epoxying a stone into a bezel set piece and they had not mentioned
any adverse reactions in the article. So you may be ok. Then i got to
thinking-People use epoxies to make triplet and doublet opals too, I
haven’t heard of any negatives there either and know that many many
are plated and sold at major retailers, rer

it should be pointed out that epoxies are not solvent based, and
cured epoxy wouldn’t have remaining volatile or soluable componants.
Glues like E6000, are solvent based, so they’d be a different
question. Wasn’t the original question about E6000? If not, (and I’m
being too lazy to go look) the distinction still should be made.
Organic materials that are not soluable or attacked by a given
plating solution could not then contaminate it, as they’d not change
the chemistry of the solution.
