Product Introduction
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℃ to 50℃, it could still keep flexibility, never vulcanize and fracture after curing time from -50℃ to 150℃.
Executive Standard: JC/T882-2001
Product Characteristics
Don’t need drop priming, it has strong adhesive force to major construction material after curing, but the surface must clean and no oilless.
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.
Main Purpose
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.

Recommendation for Use
Make material compatibility test before use, it could be constructed only if it is according to the construction requirement.
Paste the low adhesive tape on protection part: trimming and remove adhesive tape before sulfuration of the sealant.
Cut open nozzle, press the glue gun to nozzle, structural sealant is good contact with nozzle.
Attention
1. the non-curing structural sealant could release volatility substance, breathe high concentration volatility compound cuase damage to one’ health in long term, so the working place should keep good ventilation.
2. the non-curing structural sealant can’t contact with skin in long term, If it enter into eyes, it must immediately clean by plentiful of clean water and go to see a doctor.
