This agent must be add by many time with a small quantity. If not, fewer electrostatic spark and over heat from barrel will cause material burning during the mixing time, The fire can be put out by foam extinguisher.

Notes:
1. Avoid to contact with rust, heavy metal compound, metal salt, drying agent etc.
2. High vapour pressure agent easy to volatilize. Please sealed stored on free time.
3. The mixed silicone should be used up within 12 hours. If not, the curing time will be longer than before.
 
Storage and Shelf Life:
Keep in dark and ventilate place,away from light and fire.Storage for 6months below 25°C without open.
 
Packing:
    1KG  Or 20KG/Bottle.

Chemical Properties
colourless to light yellow liquid
General Description
Clear, yellow liquid. also for storage and transport mixed with inert solid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Peroxides, such as 2,5-DIMETHYL-2,5-DI-(TERT-BUTYLPEROXY)HEXANE, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. Danger of explosion when dry. May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames.
