SI 7311 Transparent Fast Cured silicone adhesive
SI 7311 is a one-component, quick skin curing, non-corrosive silicone adhesive sealant that cures to form elastic silicone rubber when exposed to moisture.
SI 7311 has excellent non-corrosive adhesion to metals including copper, plastic, ceramics, glass, etc., without the use of a primer.
Excellent resistance to high and low temperatures :-60℃ to 260℃.
Excellent chemical resistance, resistance to moisture, dirt and other atmospheric components.
Reduces mechanical stress and tension caused by mechanical, thermal shock and vibration. Easy to use single-component system.
SI 7311 has the following features:
Room temperature curing
Resistance to moisture and other harsh environments
Good dielectric properties
Self-adsorption strength
Low pressure
Application area
LED lamp seal, plastic metal shell seal; PCB board components, wiring harness fixed
Coatings for electronic accessories, electrical appliances and communication equipment
