Longyunsi 998 is single neutral, room temperature curing, high
performance structural sealant for construction,it has no influence
in ultraviolet radiation, sun, rain, ice, snow or high temperature.
The construction could keep essence unchanged from -10°C to 50°C,
it could still keep flexibility, never vulcanize and fracture after
curing time from -50°C to 150°C.
Executive Standard: JC/T882-2001
Don’t need drop priming, it has strong adhesive force to major
construction material after curing, but the surface must clean and
Outstanding weather and aging performance resistance
It can’t react to other material or rust action, it could use at
once, don’t need mix activator or other raw material.
Longyunsi 998 single component silicone structural sealant can be
used in the structural assembly of construction curtain: used in
major construction material; such as glass, aluminum material,
stone material, metal material, including most fluorocarbon baking
material, don’t need drop priming, it has outstanding cohesiveness.
