Two component polysulphide based outer sealant
for insulating glass units
Sealant components A and B react with each other. Component
B acts as a catalyst promoting the build-up of the backbone
consisting of polymer of component A. It is essential to apply
component A of TENAGLASS®-PS EN only in mixture with
component B of TENAGLASS®-PS EN. Avoid contamination of
TENAGLASS®-PS EN with previously used sealants. The deviations
of component B quantity ± 20 % from the nominal quantity will
not affect the IGU production control parameters remarkably.
Excess quantity of component B will speed up the initial curing
but can seriously affect the adhesive properties. Insufficient
quantity of component B will slow down the curing speed and
will lower the mechanical strength. Any deviations from nominal
mixing ratio can affect the permeability and durability of the edge
seal. Keep in mind that the certificates for all two component
sealants refer for nominal mixing ratio only.
Surfaces of the cavity have to be sound, clean and dry. Delete
glass coating at the edge of glass pane unless indicated otherwise
by the glass supplier.
In general, the rate of chemical reaction doubles for every 10 °C
rise in temperature. As a consequence, with temperature decrease
the pot life increases and the build-up of sealant hardness and
adhesion slows down. During the hot or cold weather make
sure that the build-up of the hardness and the adhesion is still
acceptable for the production speed, and the pot life is still long
enough to maintain the machinery in good condition.
Temperature also influences the flow properties of the
components and the mixed sealant. Drop of temperature rises the
viscosity of the compounds and higher pumping capacity of the
dispensing device is required.
Before the application of the sealant always perform the tests
to make sure that all materials having direct or indirect contact
are compatible and do not change or affect the properties of
each other. This applies especially to IGU inner sealants and, if
applicable, adhesives for direct glazing and weatherproofing
gaskets and sealants. TENAGLASS®-PS EN is compatible with
IGU inner sealants TENAGLASS®, glazing adhesives TENABOND®
and weatherproofing sealants TENALUX®. For the use of
TENAGLASS®-PS EN in combination with other sealants and
adhesives the manufacturer’s approval is required. If other
polymeric constituents can be influenced by this sealant, please
refer to the respective material suppliers. In case of doubt always
choose the design of the glazed structure where the sealant is in
contact only with the tested materials, i.e., avoid any direct contact
between IGU outer sealant and any other constituent containing
the migrating substances.
Use automated or hand operated IGU production machinery
for mixing and application of sealant. Avoid contamination of
component B with moisture. Always follow advised mixing ratio
given on packaging to obtain the best results. For machine
adjustment check the mix properties in mixing ratio range ± 20
% from the nominal quantity of component B. Apply methods for
mixing quality control in accordance with EN 1279-6 or similar.
Please refer to user manual of dispensing equipment
manufacturer as well as special instructions for TENAGLASS®-PS EN
Please refer to information given in safety data sheet for
TENAGLASS®-PS EN. Follow actual legislation requirements in the
place of product application. Always use individual protection
measures when working with sealant. Avoid the contact of
uncured sealant with skin.
Waste of sealant and materials contaminated by it have to be
collected and turned to waste deposit area. Contact your local or
regional authorities for disposal options.

When choosing the design of bonded glazing, take into account
that the strength of IGU sealant usually is much lower than the
strength of glazing adhesive, and the cut edges of glass panes are
coated with sealant. It is more reliable to choose adhesive bond
with rigid substrates, i.e., whenever possible, bond the face of
glass pane to the frame structure.
