RTV adhesive sealants-kn300series
13 Jul 2020
RTV Silicone,Silicone Bonding Glue Cured At Room
Silicone adhesive/sealant (KN-300 series)one component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapours are released from the sealant surface as a by-product of cure.
Can be applied to stick silicone with nylon, fiber, hair, paper,glass, metals, clothes, plastic as preferably. It’s characterized by high tear strength ( cohesive failure), temperature resistance (-60~280°C), ozone resistance, UV-Resistance and electrical insulating property.
Application:
Widely used for electron, electrical appliance, Automobile, Instrument, Machinery and Chemical etc.
Physical properties:
Appearance: Colorless and semi-transparent pasty
Viscosity: 10000 Pa·s (60kg/cm)
