Applying security film
to your glass and creating a bond from the glass and
film to the window frame is a highly regarded
security measure in retrofitting the existing glass
area in your home or facility. The use of Dow
Corning 995 silicone structural glazing sealant is
by far the preferred anchoring method to ensure a
more complete bond under a variety of anchoring
applications. There has been some reluctance in
using the Dow 995 by many technicians because it can
be time consuming and difficult to make an
aesthetically appealing bead and for that bead to
meet the desired installation criteria.

as specified by Dow Corning*
When the technician
prepares for the installation of the Dow 995 he must
mask the area where the bead is to be applied assuring
the correct amount of material will contact the film and
the window frame. He must then apply the silicone in a
continuous bead then smooth the silicone with a tool.
After great care is taken he can remove the masking and
hope the customer likes the appearance of the wide bead
of silicone on their window.
The BondKap®
System assures the Dow 995 has the correct amount of
contact to both surfaces and leaves a very finished
appearance. During the application no tape or tooling is
required. The technician measures the opening, marks the
area to be cut with the corner template and cuts the
Bondkap®. He then applies the Dow 995 and
presses the BondKap® in position. The BondKap®
will self center and any silicone that oozes past can be
easily cleaned up with a plastic razor blade and
cleaner. This will leave an original manufactured look
with mitered corners and no need to worry about someone
touching the silicone and tracking it around the
facility.

Since the BondKap®
System assures the shape and contact area as specified
by Dow Corning during testing the BondKap®
system also meets all testing specific to the
application of Dow Corning 995 and has passed
independent testing for adhesion and durability from a
potential cyclic event.
