Debubblizers


#1

After years of using a debubblizer, I began to have very poor
surfaces. I wondered if it was because the debubblizer had
become too concentrated due to evaporation. It seemed to leave
the wax surfaces ‘sticky looking’ and I think it affected the
investment at the surface of the waxes. I quite using the
solution and had much better surfaces. I was only using a
vibrator with the investing as I have no vacuum as yet (the more
I hear about it here, the more I want one). Does any one know what
the base for the debubblizers is? I know there was evaporation
as the container’s level would decrease, and it is meant to
evaporated off the model.

Hi Lorri, The base on many of the debublizers is (i believe)
rubbing alcohol.some solutions don’t use alcohol at all.We have
been using R&R investment and have been having good results
without debublizer. Some of the less expensive investments on the
market seem to have a problem staying consistent and we have seen
surface deterioration on some batches. Daniel Grandi

Daniel, Thanks for the info. I have been having fairly good
results without debubblizer, using Kerr Satin Cast. I think I
will try others. Lorri

Hi Lorri,   The base on many of the debublizers is (i believe)

G’day I’m always hearing of ‘rubbing alcohol’, so what is it? I
suspect it might be iso propyl alcohol. Is it? We have ‘white
meths spirit’ here which nurses use for that purpose which is
just ethanol with a little methyl alcohol added to make it
unpalatable (it doesn’t). It’s the same stuff we buy as 'meths’
in the hardware and paint stores only that is coloured violet to
stop people drinking it. (It doesn’t) Cheers,

Both Isopropyl and methanol are sold as rubbing alcohol. Both
were used as part of massage rubdowns for tired achy muscles and
to prevent bedsores. MP

It’s just a generic term for light alcohols. Usually isopropanol
or ethanol (denatured, unless you want an expensive rub) around
70% concentration.

We have ‘white
meths spirit’ here which nurses use for that purpose which is
just ethanol with a little methyl alcohol added to make it
unpalatable (it doesn’t).

Yep, that would do fine for “rubbing alcohol.” I don’t know
that the methanol makes it unpalatable (never tried it ) but
it does make it dangerous to ingest.

It’s the same stuff we buy as 'meths’

Hardware and paint stores sometimes sell pure methanol, as well.

Right on John!

The stuff sold in drug stores in the US is usually 70% iso
propyl, the 30% is water.

The stuff sold as denatured alcohol in hardware & paint stores
has the following ingredients: ethanol, methanol, methyl
isobutyl, ethyl acetate, rubber solvent & water. Sorry, the
percentages of each aren’t listed.
