PU Sealant for Glazing with high strength Two Parts Silicone
Structural Glazing Sealant Hot on Sale
Description
SV – 8000 two-component polyurethane insulating glass sealant is a
neutral cure, mainly used for the insulating glass of the second
seal. Product formulation to use its performance with high modulus,
high strength, to meet the requirements of insulating glass
assembly.
Where to use
It is a two-component PU sealant that offers variable work life
with high bonding strength to maintain the integrity of insulating
glass unit, suits both commercial and residential IGU.
Key Features
1. High Modulus
2. UV resistance
3. Low vapor and gas transmission
4. Primerless adhesion to coated glass

Application
Attentions
Use restrictions
SV-8000 products will be used in structural wall assembly.
All materials used in engineering are successful by sticky relay
and compatibility test
SV-8000 do not contact with any acidic sealant
This product is not tested does not apply to medical USES.
The construction application
In order to achieve the best physical properties SV-8000 should be
the main agent and curing agent with airtight hybrid system.
SV-8000 applies to general a two-component silicone rubber mixing
machine on the market. Whatever mixing by hand or with a hand mixer
will not bring a satisfactory effect, that is because mixture once
joined the air would make its original nature changed.
PU SV-8000 insulating glass sealant without lot number.
SV-8000 PU insulating glass sealant curing agent before use must
first stir in order to avoid in the process of transportation may
produce precipitation phenomenon.
Due to the curing agent could react with moisture from the
atmosphere, not exposed to the air for a long time. SV-8000 product
main agent and curing agent ratio of the weight of the now. The
user can change the mix ratio weight ratio of 10:1 to 14:1 (volume
ratio by 7.5 ~ 10.5:1), regulate the coagulation time. Within the
scope of the mixture of sealant, its original characteristics there
will be no significant change. But if the humidity of the air or
omit, will influence the period of testing time and the time
required to form a bond.
To get the right mix ratio, please contact Siway or mixing machine
manufacturer.
Must be used immediately after turning sealant tool to press it
gently into the interface and finishing, to ensure that it can
completely within the bonding at the interface on the surface,
resulting in better effect. Before shutdown, please only use the
main agent into the mixer and the conveying pipe, and using the
main agent to wash it. This will prevent sealant cause blockage in
the internal curing.
To learn more about SV-8000 products of detailed information,
please contact the local representative or designated agents. Our
lab and technical staff ready to provide assistance.
Surface cleaning
All retained in the bonding surface residual moisture, dust, oil,
paint, travel-weary sealant, fittings and protective coating
completely clear.
primer
Using PU SV-8000 insulating glass sealant typically don't need a
primer, but if the test report need to use primer bonding, with
clean before get sealant in an excuse not to take off the velvet
cloth will primer apply a thin layer on the surface and stay dry
dry solid. Before it becomes sealant required test to determine
whether need primer.
Glue machine clean
When it is completed should be cleaned immediately to the main
agent or in an appropriate solvent cleaning glue gun. Such as glue
gun head in case of curing structural adhesive, is in the right
time in solvent in addition to clear it.
Note
If you want the TDS or MSDS or other details, please contact with
our sales person.
