<DIV><FONT face=Arial size=2> Some helpful information on
glues:</FONT></DIV>
<DIV><FONT face=Arial size=2>White glue (Elmer's, consumer grade glue,
etc..,) and yellow glue (Titebond, industrial grade wood glue,
etc..) are both PVA'S, (Polyvinyl Acetate) and both are "Aliphatic
Resins". PVC-E glue is also in the PVA family with a few different compounds
added to make it remain semi-flexible when dry. Aliphatic Resin is a
general chemistry term that implies "at the molecular level, these products
(glues, etc..) arrange themselves in chains". When yellow glue came
out, manufacturers needed a fancy slogan to differentiate yellow
glue from white glue so they called it Aliphatic resin, but in
reality, not economy, they both are Aliphatic Resin. A lot of
the Yellow Glues are stronger than the White Glues, but they are both PVA'S
and are both Aliphatic Resins. PVA'S are further broken down into subgroups
based on their strength, application, water resistance etc.. The PVA'S are a
huge family of glues that most of us use and think they are something distinctly
different because of what they are called or what someone recommends they be
used for. Choose your glues carefully, any supplier/manufacturer can supply you
with a specifications sheet or MSDS, this will give you the properties of the
glue and most importantly will tell you what the MANUFACTURER created the glue
for, not simply what a supply house markets it as. Of all the glue books I
have read, "The Glue Book" by William Tandy Young makes all this easy to
understand. Remember, spare the next technician the pain of fixing an improper
glue job, because the next technician might be you. I think Reblitz said
something like that first.</FONT></DIV>

<DIV><BR></DIV><FONT face=arial size=2>Julia,<BR> I use a
Cold liquid hide glue when I'm traveling and use the glue pot in my
shop. An Aliphatic glue is what is more commonly known as 'yellow wood
glue'. Here is a run-down of glues that I use and thier common
uses:<BR><BR>PVA for non-critical wood joints. Be careful, it
creeps. Provides good working time<BR>Aliphatic (yellow wood glue) for
common woodworking tasks, but doesn't work well with shear stress.
<BR>Hot Hide Glue (use urea to adjust working time). Good for hanging
hammers and rigid wood joints. Works well for felt and leather because
it doesn't soak in much.<BR>Cold Hide Glue. Long working time.
General wood working tasks and rigid wood joints<BR>PVC-E. Use for
rubber buttons and felt trim. It's water resistant. It also creeps
a good bit.<BR>Contact cement. Water resistant, creeps. Good for
understring felt. <BR>Epoxy for jobs where I need to fill wood
gaps. It's waterproof. Good for bridge work<BR>Cyanoacrylates
(Super Glue)(CA). Used for small cracks, veneer, and tuning pin
tightening. Comes in different varieties (gap filling, thin, etc... for
different purposes).<BR><BR>Hope this helps.<BR>Joey

glue sticks</FONT><BR><BR>
<DIV>Greetings, </DIV>
<DIV> </DIV>
<DIV> Reading Reblitz"s book, he mentions heated
glue pots! Wow! To carry such a monstrostity in your car trunk! I was
wondering if craft glue sticks are the same thing; Are they? Also, what
is <EM><STRONG>aliphatic</STRONG></EM> glue?</DIV>
<DIV> </DIV>
<DIV>Thanks </DIV>
