Applications :
It can solidify together with crosslinking agents and activators at room temperature. It can remain elasticity for a long time at temperature range of -60~200°C with excellent electrical performances and chemical stability and property of waterproof, odor resistance and weather proof resistance. It is widely used in many areas such as caulking joint in construction; insulation, antishock, dampproof and anticorrosion for electronic components; moulding and demoulding for rubber products, smooth agents and isolating agents for leathers. It is also a basic material for manufacture of RTV-1,RTV-2 with special specification used in fabric finishing and daily-use chemical industry.
Hazard Characteristics incombustible, harm –free, avoid contacting with eyes.
Stability Stable
Polymerized Danger free of being polymerized
Banned Articles : may lead to a reaction with oxidant
Decomposition Products :silicon dioxide, carbon dioxide and minimum uncompleted combustion carbide, formaldehyde.
Package, Storage and Transportation:
It should be packed in 200L iron bucket(net weight 200kg/bucket) and be stored in a shady, cool and ventilated storehouse. It should be kept away from kindling, temperature in the storehouse above 30°C is not suitable. Avoid direct sunlight. Air proof package is required without contact with air. And it should be put and stored
separately from oxidant, acid, and alkali. The installation of lighting and ventilation in the storehouse should be explosion-proof. Switches are located outside the storehouse. Corresponding varied and quantitative fire fighting equipment should be equipped. Check regularly to make sure whether there is a leakage phenomenon. Operate and handle in nitrogen gas. When conveying, take care of loading and unloading to avoid damages on package and vessels. A regulated route is required for transportation without stay on the midway.
Quality guarantee period of this product is 6 mouths. Recheck by this standard is required when the product exceeds the time limit. The product can still be used only after the result of recheck is up to this standard.
