Can anyone advise on a source for a fixative suitable for fixing and supporting electronic components on a PCB assembly? It should be of the rigid type, so that it can support the component in case of it getting knocked, accidentally. In application, its consistency or viscosity should be somewhere between hot-melt glue stick* and silicon sealant, so that it does not slump or flow away. When it sets, it should be like 2-part epoxy, preferably with some filler to reinforce it.

A UV-curing product would be ideal.

*I don't want to use glue stick, as it does not adhere consistently; (neutral) silicon is typically too soft/flexible.
