Storage conditions
Store in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. Prevent direct sunlight. Packaging sealing. It should be stored separately from acids and edible chemicals, and mixed storage should be avoided. The storage area should be equipped with suitable materials to contain leaks.
Stability
Under the action of trace amounts of sodium silicate and potassium silicate, intramolecular Si-O-Si bonds break and rearrange, forming a mixture of direct polysiloxane and cyclic siloxane. This catalytic fracture rearrangement process has equilibrium characteristics, and at the same time as the ring opening polymerization of the ring body into polymer, macromolecular fracture degradation also occurs. It reacts with excess sodium hydroxide methanol solution to produce sodium Diphenylsilanediol.
