[Description]

Vinyl-terminated dimethylpolysiloxanes (Vinyl terminated polydimethylsiloxane) are available in various viscosities. Vinyl terminated silicone fluid is a base polymer for addition-curing RVT-2k (room temperature vulcanizing two components), LSR (liquid silicone rubber) silicone rubber. The terminalvinyl groups participate in the vulcanization reaction with Crosslinking agents in the presence of Catalysts.
[Uses]

Mold-making elastomers and encapsulants and sealants for electronic components. Vinyl terminated polymers are most often employed in 2-part addition cure silicone elastomers.
