Novol Gravit 630 Polyurethane Sealant (310ml) – High-Strength Sealing in Black
Ensure a permanent, factory-quality seal with Novol Gravit 630, a high-performance one-component polyurethane (PU) sealant. This 310ml cartridge is the professional's choice for automotive bodywork, offering a robust, elastic barrier that protects against moisture, dust, and road salt.
The Black finish is ideal for underbody applications, chassis work, and engine bays where a dark, discreet seal is required to match original factory specifications or dark paintwork.
Key Features & Benefits:
- High-Strength Elasticity: Formulated to remain flexible after curing, allowing it to absorb structural vibrations and thermal expansion without cracking.
- Superior Adhesion: Bonds instantly to a variety of substrates, including bare steel, stainless steel, aluminum, glass, and many plastics (polyester/PVC).
- Professional Corrosion Defense: Creates a non-porous, airtight seal over welded joints and lap seams to prevent rust from forming between panels.
- Overpaintable: Can be coated with all automotive 1K and 2K paint systems once a skin has formed, allowing for a perfectly integrated repair.
- Non-Shrink & Non-Sag: Thixotropic consistency ensures the bead stays exactly where you apply it, even on vertical or overhead surfaces.
- Chemical Resistance: Highly durable against water, cleaning detergents, and mild petroleum products.
Common Application Areas:
- Chassis & Underbody: Sealing floor pan joints, wheel arches, and suspension mounting areas.
- Body Panels: Sealing overlapping joints in boots, engine compartments, and door skins.
- Glass Bonding: Often used for sealing around windscreens or fixed window panels.
- Structural Welds: Providing an insulating layer over spot welds and seam welds to block moisture ingress.
