Harris Black Silicone 310ML RTV Sealant
Premium Black RTV Silicone for Waterproof Sealing & Industrial Bonding
Harris Black Silicone 310ML is a professional-grade one-part RTV silicone sealant developed for strong bonding, waterproof sealing, and long-lasting protection in construction, automotive, industrial, and household applications. This fast-curing silicone reacts with atmospheric moisture to form a highly durable, flexible rubber seal that maintains excellent performance under both high and low temperature conditions.
Designed for professional use, Harris Black Silicone 310ML delivers outstanding adhesion to glass, glazed surfaces, metals, ceramics, fiberglass, epoxy materials, coated surfaces, and most plastics. The advanced silicone formula creates a weatherproof barrier that resists moisture, UV rays, vibration, dust, and aging while maintaining permanent flexibility throughout its service life.
The black finish provides a clean and professional appearance, making it an excellent choice for window frames, curtain walls, automotive sealing, glazing work, machinery maintenance, and industrial assembly. Furthermore, the sealant effectively prevents water leakage, air infiltration, and dust penetration while protecting sensitive components from environmental damage.
In addition to construction applications, Harris Black Silicone 310ML performs exceptionally well as a formed-in-place gasket for metal flanges, engine components, mechanical assemblies, and electrical insulation. It is also suitable for fixing coils, condenser parts, transistor assemblies, and high-voltage electrical components where reliable sealing is essential.
The convenient 310ML cartridge works with standard caulking guns, allowing smooth, continuous, and bubble-free application. After installation, the sealant quickly forms a surface skin before curing into a tough yet elastic rubber seal that offers dependable long-term performance.
