2PC KJ-985 Premium Neutral Silicone Structural Sealant, Waterproof & Weatherproof, White, 300ml (10.1 fl oz) Cartridge

Bullet Points (Key Features):

• PROFESSIONAL STRUCTURAL ADHESIVE: KJ-985 is a single-component, neutral room-temperature curing silicone structural sealant specifically designed for structural bonding and assembly in building curtain walls.

• VERSATILE APPLICATION: Beyond curtain walls, it is ideal for the weatherproofing sealing and bonding of various coated metal profiles, ceramic tiles, masonry, concrete, and stone.

• SAFE & ECO-FRIENDLY: It cures by absorbing moisture from the air to form a highly elastic rubber. This formulation is non-toxic, non-corrosive, has no irritating odors, and is environmentally safe.

• OUTSTANDING PERFORMANCE: Delivers robust adhesion with a tensile strength of ≥ 1.8 Mpa (tested at 2.02 Mpa) and a maximum elongation rate of ≥ 400% (tested at 456%). Ensures over 95% cohesive failure area on glass and aluminum bonding.

• EASY TO APPLY: Features a fine, uniform paste without bubbles. It offers a fast tack-free (skin-over) time of around 40 minutes and excellent extrudability.

Product Description:

Compact the sealant with an appropriate tool and scrape off any excess.

• Storage & Shelf Life: Available in 300ml hard cartridges or 590ml sausages (customizable packaging available). Store in a cool, dry place below 27°C. Shelf life is 12 months.
