Why do I have problems gluing Acriglas®
to my stock acrylic sheet?
The
problem, if you want to call it that, may lie in the fact that you
are using a fast solvent with dissimilar materials, which absorb
the solvent at different rates. If you are using something like
a stock clear material like Acrylite® FF, which is extruded, it
will absorb methylene chloride solvent faster than the Acriglas®,
which is cast acrylic. The softer extruded material will starve
the glue joint because it has soaked up the bulk of the solvent
before the harder cast material has had a sufficient time to soften
and fuse together with the extruded.
The
solution is simple. You can either make sure you use a sufficient
amount of solvent to ensure a good bond, or slow down the rate of
absorption by cutting the solvent with 10% Glacial Acetic acid,
or buying a slower absorbing solvent to begin with. This will also
give the two dissimilar materials enough time to fuse together.
Between an adjustment to your gluing technique and a different solvent,
you should no longer experience any difficulties.
