The Novagard RTV400-150 Clear Silicone Sealant Adhesive 3 oz is a versatile, single-component silicone sealant and adhesive formulated for a wide range of applications including pool and spa maintenance, plumbing, and general repair. This neutral-cure, oxime silicone paste cures to a tough, flexible rubber-like solid upon exposure to moisture in the air, providing durable adhesion with minimal sag or flow and lower odor than traditional silicone sealants. Ideal for creating formed-in-place gaskets, bonding dissimilar materials, waterproofing joints, and sealing components exposed to weather or moisture, the RTV400-150 offers strong adhesion to many common substrates without primer and performs reliably across a broad temperature range.
