<DIV><FONT face=Arial size=2><FONT face=Arial size=2>List,</FONT></DIV>
<DIV>
<DIV><FONT face=Arial size=2> Some helpful information on
glues:</FONT></DIV>
<DIV> </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>
