ADOS Black RTV Neutral Cure Silicone Sealant — 310ml Tube (8367)

CRC’s ADOS Black RTV Neutral Cure Silicone Sealant is a contractor‑grade, single‑component sealant engineered to seal, bond, and weatherproof a wide range of materials while preserving the integrity of sensitive substrates. Designed for serious DIYers and professional trades, it delivers dependable adhesion, long‑lasting elasticity, and reliability in demanding New Zealand conditions.

Key strengths that matter on every job

• Neutral‑cure chemistry: seals with minimal substrate interaction, protecting metals, glass, ceramics, and plastics from corrosion while maintaining a clean, discreet profile.
• 310 ml tube, fast‑acting cure: ready to seal quickly at ambient temperatures with low odour, reducing downtime on interiors and exteriors.
• Permanent elasticity: remains flexible through temperature changes, resisting cracking, shrinking, and joint movement.
• High movement tolerance: accommodates up to 20% joint movement without losing seal integrity.
• Bridges 8 mm irregular gaps: versatile for gaps and awkward joints often found in real‑world construction and repair work.
• Excellent substrate adhesion: sticks strongly to zinc‑coated/galvanised metals, aluminium, fibreglass, ceramics, glass, concrete, and most plastics.
• Robust resistance: guards against oil, grease, chemicals, water, vibration, and exposure to weather—ideal for harsh outdoor environments.

Where it shines — practical applications

• Automotive and marine sealing, glazing and gasketing, and general bonding tasks where a durable, flexible seal is essential.
• Weatherproofing for windows, doors, and skylights to keep drafts and leaks at bay while withstanding wind and rain.
• Perimeter sealing for metal rooftops and spouting, providing a protective, long‑lasting weather barrier.
• Electrical and appliance assemblies where a reliable, non‑corrosive seal is required.
• Plumbing penetrations and similar penetrations where a robust, waterproof seal is needed (avoid petrol or diesel exposure in service).
• Ideal for windshields, exterior trims, panels, and other outdoor installations requiring enduring adhesion and flexibility.

Why this sealant is a smart choice

Unlike generic sealants, ADOS Black RTV Neutral Cure Silicone Sealant combines a low odour profile with a fast ambient‑temperature cure, making it suitable for indoor projects without compromising outdoor performance. The neutral‑cure formulation protects sensitive substrates from corrosion, while the black color blends seamlessly with many profiles used in construction and automotive work. This makes it an excellent option for OEM tasks, bulk projects, and site work where consistent results, repeatability, and professional finish matter.

Tips for best results

• Prepare surfaces by cleaning and drying; remove old sealant residues for optimal adhesion.
• Apply at moderate humidity and temperature to maximize cure speed and performance.
• Fill joints fully, then smooth with a compatible tool before skin forms for a neat, professional seal.
• For indoor use, ensure adequate ventilation during curing; avoid prolonged exposure to fuels or solvents near cured sealant.
• Store upright in a cool, dry place, away from direct heat and sunlight to preserve the tube contents.
