Hints for Handling CA
NEVER use the system without first protecting the inside surfaces of the
clear chamber with Rain-X
®
or Rain Block
TM
glass water repellent.
Labconco has tested these two treatments, and found they protect the
clear chamber from CA fumes for up to 20 uses, if the treatment is not
disturbed. Always follow the treatment manufacturer’s instructions when
applying the treatment. Labconco has not tested any other brands of glass
treatment chemicals, and cannot recommend their usage.
CA will react and polymerize on any surface or material that is wet or
damp. NEVER use the system on wet or damp evidence.
If you are trying to reuse CA heating pans, discard them after the second
use. If reused more than a single time, buildup of residue on the bottom of
the pan will affect the transfer of heat to the glue.
Don’t use any heating pan with a dented or warped bottom; it will not heat
the CA as efficiently.
Because the presence of moisture causes the glue to set, exposure to
moisture in the air can cause a tube or bottle of glue to become unusable
over time. To prevent an opened container of glue from setting during long
term storage, store it in a freezer, or in an airtight jar or bottle with a
package of silica gel.
