Product Description
High Performance Curtain Silicone Weatherproof Sealant for Senior Project engineering bonding
Silicone weatherproof sealant is one component, impartial therapy silicone sealant, designed for glass curtain wall, aluminum curtain wall and constructing outdoors design, has amazing weathering properties, it may shape long lasting and maximum constructing materials, water-resistant and bendy interface.
One component, neutral room temperature curing, easy to use, good extrudability and thixotropy.
High elongation, high elasticity, good tensile and compressive restoring force, displacement capacity up to 25 level.
High weathering resistance and UV resistance for ozone, rain, snow and ice and other properties.
Good high and low temperature resistance to most materials have good adhesion without substrate coating.
Application
Glass and aluminum curtain wall and other non-structural waterproof weatherproof seal;
Weatherproof sealing of glass, metal, concrete, stone and other building materials;
Aluminum doors and Windows, aluminum plastic plate and other engineering bonding seal.

Construction operation
- Conduct compatibility and adhesion test of contact materials before use;
- Clean the surface of the substrate to be bonded;
- Extrude the glue from the barrel to the interface with the glue gun;
- During construction, the joint shall be completely filled with sealant to ensure the bonding of both sides;
- Trim the edge before the glue is cured;
- Strike in a ventilated place;
Usage restriction
After gluing, it is not advisable to completely isolate the air before the glue is cured;
Do not use material surfaces that seep out grease, plasticizers or other organic solvents;
Frost or wet surfaces should not be soaked in water for a long time;
It is not suitable for construction when the surface temperature of building materials is lower than 4°C or higher than 40°C.
It is not recommended to be used as stone glue.
