SV-8000 Two Component PU Polyurethane Sealant for Insulating Glass
Product Selling Points
Exceptional Gas Barrier Performance
Formulated as a premium secondary barrier sealant for IG units, SV-8000 offers an extremely low vapor and gas transmission rate. It perfectly locks in argon gas, ensuring the long-term energy efficiency and thermal insulation performance of modern windows.
Primerless Adhesion to Coated Glass
Achieve maximum bonding strength without the hassle of primers. SV-8000 provides outstanding, heavy-duty primerless adhesion to coated glass, Low-E glass, and aluminum spacers, significantly speeding up your factory’s assembly line.
High Modulus & Structural Integrity
Engineered with high tensile strength (1.0MPa vs. standard >0.4 MPa) and high modulus. It creates a robust, elastic bond that withstands severe wind loads and thermal expansion, making it the ideal two-component polyurethane insulating glass sealant for commercial curtain walls.
Optimized for Automatic Dispensing Lines
With a non-sagging formula (0mm sag) and an adjustable 30-minute pot life, SV-8000 is perfectly tailored for automatic continuous dispensing lines and manual mixing guns alike. Smooth extrudability ensures zero waste and neat sealant lines.

CURE TIME
As exposed to air, SV8000 begins to cure inward from surface. Its tack free time is about 50 minutes; the full and optimal adhesion depends on the sealant depth.
SPECIFICATIONS
SV8000 is designed to meet or even exceed the requirements of:
* Chinese national specification GB/T 14683-2003 20HM
STORAGE AND SHELF LIFE
SV8000 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
HOW TO USE
Surface Preparation
Clean all joints removing all foreign matter and contaminants such as oil, grease, dust, water, frost, old sealants, surface dirt, or glazing compounds and protective coatings.
Application Method
Mask areas adjacent to joints to ensure neat sealant lines. Apply SV8000 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the joint surfaces. Remove masking tape as soon as the bead is tooled.
