Rapidstick™ RTV Silicone Sealant & Adhesive

RS81 RTV Silicone Sealant & Adhesive is a high-performance room temperature vulcanising (RTV) silicone designed for a wide variety of applications, including both domestic and industrial assemblies. Once exposed to moisture in the air, it cures to form a durable, waterproof, mildew- and mould-resistant seal on most surfaces. RS81 won’t shrink or crack, resists weathering, and is sensor-safe, making it suitable for a broad range of applications, from automotive repairs to HVAC systems and plumbing.

In addition to its use in sealing gaps, cracks, and joints, Rapidstick™ RS81 is commonly applied in automotive repairs, sealing windshields, electrical connections, and even as a gasket maker for engines. It is perfect for marine, industrial, and construction uses such as sealing vents, ducts, or windows, and for waterproofing outdoor equipment. With its wide versatility, RTV silicone is ideal for any project requiring a tough, long-lasting, and flexible seal.
