Harris White Silicone 310ml RTV Sealant
Professional Weatherproof Silicone Sealant for Construction, Glazing & Repairs
Harris White Silicone 310ml is a premium one-part RTV silicone sealant designed to provide durable sealing, waterproof protection, and long-lasting adhesion for construction, industrial, and household applications. This fast-curing silicone reacts with atmospheric moisture to form a strong, flexible rubber seal that delivers outstanding performance under both high and low temperature conditions.
Formulated with advanced silicone technology, Harris White Silicone 310ml offers excellent adhesion to glass, glazed surfaces, metals, ceramics, fiberglass, coated materials, most plastics, and epoxy surfaces. The high-strength elastic seal resists cracking, shrinking, moisture penetration, UV exposure, and weathering, making it ideal for both interior and exterior sealing projects.
The white silicone sealant is widely used for glazing installations, window and door sealing, sanitary applications, electrical insulation, gasket formation, and general-purpose construction work. It creates a permanent waterproof barrier that protects joints against dust, moisture, vibration, and air leakage while maintaining flexibility over time.
In addition, Harris White Silicone 310ml is suitable for sealing electrical components, condensers, transistor assemblies, high-voltage parts, and metal flanges. It can also replace conventional cut gaskets by forming reliable in-place seals that effectively prevent fluid and air leaks in mechanical systems.
The easy-to-use cartridge is compatible with standard caulking guns, allowing smooth, bubble-free application and professional finishing. Once applied, the sealant quickly develops a surface skin and continues curing to provide maximum strength and durability.
