The term is hydrolyzate.

The trifluoropropyl methyl hydrolyzate has silanol terminal groups. To
blow a foam, you need a polyfunctional SiH material miscible with the
trifluoropropyl polymer, a small amount of an alcohol, and a tin (or
less often, platinum) catalyst. Exact formulation determines the set
time and stiffness of the resulting foam. Sitting at home, I'm not 100%
sure if a methyl hydrogen polymer such as Dow Corning 1107 fluid is
miscible or not with the fluoropropyl polymer. Can't you get tech
support from one of the major silicone companies. I'd suggest Dow
Corning, GE or Wacker. I believe all three have formulated products of
this type.
