• Synonyms: 3,3,5,5-tetramethyl-3,5-disila-4-oxa-1,6-heptadiene;Divinyltetramethyldi;1,3-DIVINyltetraMETHYLDISILOXANE;Tetramethyldivinylsiloxane;Tetramethyl-1,3-divinyldisiloxane
• IUPAC Name: ethenyl-[ethenyl(dimethyl)silyl]oxy-dimethylsilane
• Molecular Weight: 186.4 g/mol
• Molecular Formula: C8H18OSi2
• Canonical SMILES: C[Si](C)(C=C)O[Si](C)(C)C=C
• InChI Key: BITPLIXHRASDQB-UHFFFAOYSA-N
• Boiling Point: 139 °C
• Melting Point: -99.7ºC
• Flash Point: 24ºC
• Density: 0.813
• Appearance: Colorless liquid
• Application: It 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 139c, 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.
