RTV Silicone, Silicone Bonding Glue Cured At Room Temperature

Model No.: KN-300N |  KN-300A  | KN-300X(Slow) KN-300T (For PCB) 




Product Description
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.

Silicone glue cured at room temperature good bond strength
silicone to silicone bonding                                       silicone to ceramic bonding                         
silicone to metal bonding                                           silicone to glass bonding
silicone to ABS bonding                                               silicone to paper bonding 
silicone to PVC bonding                                               Silicone to Nylon bonding
silicone to plastic bonding                                           silicone to stainless steel bonding

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)
Elongation: 200%
Hardness: 50 Shore A
Specific Gravity: 1.10


Usage 1:
1, Surface treatment: Metal cleaned by toluene, Plastic cleaned by absolute ethyl alcohol.
2, Gluing: The gluing thickness less than or equal to (≤) 5mm
3, Pressing: More than 30 munites pressing, Absolutely cured after 24 hours at 25°C.


Usage 2:
1, Cleaning: Cleaning the bonding surface with toluene or absolute ethyl alcohol
2, Activating: Brushing fewer adhesive(CL-24S-3) on the cleaned surface.(single brushing is enough)
3, Curing: Curing at room temperature for 30minutes or curing at 90°C for 5-15mintues.
4, Gluing: After tackifier cured, Brushing KN-300A on the bonding surface, pressing over 120minutes. Absolutely cured after 24 hours at 25°C

1, KN-300A is easy to cure once contacting with moisture, it must be stored in a completely sealed place and away from the sunlight.
2, Avoid eye contact. If irritation occurs, flush eye(s) with lukewarm gently flowing water for 5 minutes or obtain medical attention.
3, Please fasten down the the cover after using to avoid the gel to be cured.
