## Abstract

Gel compositions are disclosed comprising a silicone elastomer from the reaction of an SiH containing organopolysiloxane resin and an organic compound having at least two aliphatic unsaturated groups in its molecule.

## Claims

### Claim 1

A gel composition comprising:
a silicone elastomer from the reaction of;
A) an SiH containing MQ resin comprising the formula

where
a is greater than 0
b is from 0 to 0.8
e is 0 to 0.9,
with the provisos that the sum of a, b, and e is at least 0.95 and e is greater than 0,
Me is methyl,
B) an organic compound having at least two aliphatic unsaturated groups in its molecule selected from
H2C═CHCH2O[C3H6O]gCH2CH═CH2,
H2C═CHO[C3H6O]gCH═CH2,
HC≡CCH3O[C3H6O]gCH2C≡CH2
HC≡CC(CH3)2O[C3H6O]gC(CH3)2C≡CH, or
H2C═C(CH3)CH2O[C3H6O]gCH2C(CH3)═CH2,
where g is greater than 2,
and
C) a hydrosilylation catalyst,
