Application: Being a basic material of organosilicon, it is mainly used in crosslinker, silicone, special coating, construction water repellant for the production of methyl trimethoxysilane etc., collapse resistant(methyl sodium silicate ) used in drilling wells on oil field.
Characteristics: Inflammation and explosion will arise when it meets naked fire, high heat or oxidant. And it will decompose with exothermic heat and poisonous caustic smoke when it is heated or encounters water. Interior pressure in the vessel increases leading to the danger of splitting and explosion when it meets high heat, It is of causticity.
Danger: Free of being polymerized
Condition to Avoid
Being Contacted: Air's
Banned Articles: Strong oxidant, alkali, water, strong acid
Products: Carbon monoxide, carbon dioxide, monox, chlorine hydride, phosgene
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 months, 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.
