Typical Technical Data

The below values are not intended for use in preparing specifications. Please confirm with us prior to writing specifications on this product.

Appearance: Colorless transparent liquid

Density (25°C): 0.818

Refractive Index (): 1.4118-1.4123

Purity (by GC, %): 99 min

The vinyl content: 27.5% (the quality of analytical grade)

 

Applications

USi-O6214 is used as a linear inhibitor in the formulating of two-part Silicone RTV-2 Addition Curing systems.

Because of the large vinyl content, small amounts are very effective in retarding and controlling the working time or pot life of two-part Addition-Curing Silicone RTVs.

Also, due to its boiling point of 139, it is easily volatilized during curing. A suggested starting formulation is to use 0.25 to 0.50 parts by weight of USi-O6214 with 100 parts of the Base polymer containing the platinum catalyst.

 

Packaging

In 20kg, and 160kg drum
