Use restrictions
SV-8000 products can not 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.
