Product Description
WACKER SG-79 Structural Silicone Sealant is a high-quality alkoxy silicone sealant, specially designed for Structural Glazing applications. The product provides strong adhesion, high elasticity, and movement capability of ±50%, making it suitable for projects requiring long-term stability, safety, and durability.
WACKER SG-79 Structural Silicone Sealant offers excellent weather resistance, withstanding sunlight, UV radiation, rain, wind, and environmental vibration. This ensures glass systems remain firmly bonded without peeling over time. Moisture-curing technology allows easy application, produces no acidic odor, and is more friendly to users and metal substrates.
Applications
Curtain wall systems, structural glazing.
Glass-to-aluminum frame bonding in high-rise buildings.
Sealing joints subject to vibration and large expansion movement.
Civil and industrial construction applications requiring long-term durability.
Glass partitions, glass doors, steel and aluminum structural frames.
Benefits
Provides maximum safety for structural glass projects.
Minimizes sealant peeling and joint cracking.
Maintains stable strength and elasticity in harsh environments.
Easy application, saving time and labor cost.
Extends overall service life of the construction.
Key Features
High elasticity with movement capability of ±50%, ideal for large structures.
Excellent weather resistance, durable against UV, rain, and high temperatures.
Strong and stable adhesion on various non-porous substrates.
Non-sagging, smooth extrusion, easy bead control.
High mechanical strength: strong tensile strength and good elongation.
Long service life, suitable for projects with high safety requirements.
Instructions
Surface preparation: Clean dust, oil, rust, and contaminants thoroughly.
Cartridge preparation: Cut cartridge tip, attach nozzle, load into sealant gun.
Application: Apply sealant in a continuous, even bead. Moisture is required for curing; skin formation time is approximately 60–90 minutes.
Note: Low humidity or low temperature will extend curing time. Compatibility testing with surrounding materials is recommended, especially materials containing plasticizers.
Shelf Life
Shelf life is according to the information printed on the packaging (best before date).
Storage
To maintain product quality and durability, store in a dry, cool place. Avoid direct sunlight, heat sources, or fire.
Safety Precautions
Do not inhale vapors for prolonged periods.
In case of contact with eyes or mouth, rinse immediately with clean water.
Avoid prolonged skin contact before curing.
Keep out of reach of children.
Not suitable for continuously submerged areas.
Not suitable for food-contact surfaces.
Not compatible with PP and PE materials.
Avoid application in poorly ventilated areas – the product releases methanol during curing.
