Product Description
Silicone sealant is a versatile, paste-like material, typically supplied in a single-component cartridge, that cures at room temperature to form a durable, flexible rubber seal.Its core ingredient is Polydimethylsiloxane (PDMS) polymer. When dispensed, it reacts with moisture in the air (a process called room-temperature vulcanization) to solidify from the surface inward, creating a strong, elastic bond.
Key Properties and Advantages
Key Properties and Advantages
The unique chemical structure of silicone gives these sealants superior performance characteristics.
Exceptional Durability & Weather Resistance: Possesses strong resistance to sunlight (UV), ozone,ensuring a service life that can exceed 20 years in outdoor applications.
Superior Flexibility and Movement Capability: Maintains elasticity, allowing it to absorb the movement, vibrations, and thermal expansion/contraction of building materials without cracking or losing adhesion.
Excellent Water and Chemical Resistance: Exhibits strong hydrophobicity, making it ideal for waterproof sealing. It also resists moisture, aging, and many common chemicals.
Strong Adhesion to Common Substrates: Bonds effectively to a wide range of materials including glass, metal, ceramic, wood, and many plastics and painted surfaces
Application
Construction & Glazing: The most common use, including structural glazing for curtain walls, weatherproof sealing for perimeters (windows, doors), and expansion joints in concrete.
Sanitary & Wet Areas: Perfect for sealing around bathtubs, showers, sinks, and tiles due to its waterproof and mold-resistant properties (look for specific mold-resistant formulations).
Industrial & Automotive Assembly: Used for gasketing, sealing enclosures, bonding interior components, and in appliances due to its temperature and environmental stability.
Specialty Uses: Includes high-performance types for aircraft/automotive (fluorosilicone for fuel resistance), electronics (non-corrosive), and low-modulus sealants for sensitive materials like precast concrete.
