Novagard RTV400-150 Clear Silicone Sealant Adhesive | 3 oz

The Novagard RTV400-150 Clear Silicone Sealant Adhesive 3 oz is a single-component silicone formulated for sealing, bonding, and gasketing applications commonly found in pool and spa maintenance, plumbing, and general repair work. This neutral-cure oxime silicone cures when exposed to ambient moisture, forming a tough yet flexible rubber-like seal that resists cracking, shrinking, and vibration. Its non-sag consistency allows for controlled application on vertical or overhead surfaces while producing significantly lower odor than acetoxy-based silicones. Designed for use without primer, the RTV400-150 adheres to a wide range of substrates including metal, glass, plastic, and wood. It performs reliably across a broad temperature range, making it suitable for both indoor and outdoor sealing tasks exposed to moisture or weather.

Highlights

• Single-Component Oxime Silicone: Ready-to-use formula cures upon contact with moisture in the air, eliminating the need for mixing, catalysts, or additional preparation.

• Flexible Rubber-Like Seal: Cures into a durable elastomer that resists cracking, shrinking, and vibration, supporting long-term sealing performance.

• Low Odor Non-Sag Formula: Neutral-cure composition produces less odor than traditional acetoxy silicones and maintains placement on vertical surfaces.

• Broad Temperature Performance: Designed to maintain sealing integrity across extreme temperature variations for indoor or outdoor applications.

• Multi-Substrate Adhesion: Bonds and seals common materials including metal, glass, plastics, wood, and composites without the need for primer.
