TECHNICAL DATA SHEET
PRODUCT DESCRIPTION:
Tacky Tape
SM5142 is a sealant tape developed for vacuum
bagging operations. This product has been formulated to
outperform all tapes in its class. With aggressive initial
tack, it will maintain an air-tight seal during the cure cycle,
yet strip clean from the tool, with virtually no trace of residue.
SM5142 provides easy, almost effortless de-bagging, and
minimal to no clean-up between production cycles. SM5142
exhibits these excellent usage and release characteristics
from composite and metal tools, in both oven and autoclave
applications. This tape has an optimum cure temperature range
of room temperature to 400
o
F (204 C).

APPLICATION:
Apply by hand to a clean dry tool or platen with release paper on
top. When the sealant is in position remove the release paper
and lay the film on top. Apply pressure by hand or roller on the
sealant to obtain maximum adhesion and to ensure positive
vacuum. It is recommended to strip below 150
o
F (66
o
C) to
minimize or reduce the parts from becoming warped. SM 5142
can be stripped without leaving a residue on metal and
composite tool surfaces that have been cooled to room
temperature.
