Quick Drying 2 Part Silicone Sealant , Engineering Structural Adhesive Sealant

Product Specification

Two-component Silicone Structural Sealant for insulating glass with two part strong bonding

Description

SV8890 is neutral curing, designed for glass, stone, marble, granite, aluminum curtain wall and glass daylighting roof and metal structural engineering structural adhesive seal designed silicone sealant structure, excellent bonding performance of structure and the weathering resistance, after artificial accelerated weathering test, various physical and chemical properties have no obvious change in the sealant. When using, SV8890 with dedicated two-component glue machine construction, two kinds of components in accordance with the provisions, mixing ratio after curing form elastomer.

The construction application

In order to achieve the best physical properties SV8890 silicone sealant structure should be the main agent and curing agent with airtight hybrid system. SV8890 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.

SV8890 silicone structural sealant without lot number.

SV8890 silicone sealant structure of curing agent must first stir before use 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. SV8890 silicone sealant structure of main agent and curing agent in the weight ratio of 12:1 (volume ratio of 9.1 :1). The user can change itself

Total combined ratio than 10:1 ~ 14:1 (volume ratio of 7.6:1 ~ 10.6:1) adjusting 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 zhijiang 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 tao SV8890 silicone structural sealant of detailed information,

Please contact local zhijiang company representative or designated agent. Our lab and technical staff ready to provide assistance.

Not curing sealant is absolutely not allowed with an abrasive surface, such as polished marble, metal or glass contact, because these extra sealant can not use organic solvent completely removed, so the surface must be covered, or in the construction of the sealant take extra care to prevent sealant come into contact with the surface, it will leave a layer of thin film on the surface, which will affect the base material peculiar and beautiful surface. If in the case of do not pay attention to not curing sealant and interface of adjacent non porous material surface contact, necessary before the sealant has not been solidified, using toluene, xylene and methyl ethyl ketone solvents to remove, when using flammable solvents, shall comply with the special attention.

Surface cleaning

All retained at the interface and assembly of rabbet residual moisture, dust, oil, paint, travel-weary sealant, fittings and protective coating completely removed.

Metal, glass and plastic surface solvent must be applied in accordance with the method of two pieces of cloth to wipe clean. No matter which method must with a piece of oil free, and not to take off the cloth with soft nap of clean cloth, with solvent swabs again and again with another piece of clean cloth to wipe off the residual solvents. Detergent or soap water cleaning method is not appropriate.
