Silicone Adhesive/Sealant KN-300A

　　　　　　　　　
Silicone adhesive/sealant (KN-300A) 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℃), ozone resistance, UV-Resistance and electrical insulating property.

Application:
Widely used for electron, electrical appliance, Automobile, Instrument, Machinery and Chemical etc.

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℃.

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℃ 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℃


Notes:
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.
