I'm investigating heat transfer by 1st order approximation between PCB and ambient air via encapsulate material (epoxy or gel or silicone), they have thermal conductivity of 0.2W/C but it hard to find specific heat capacity and density. Has anyone

Try Humiseal 2A53. This is a very old 2-part epoxy coating that is still used by a number of companies as well as the military. Very hard to rework, transparent and may be what you are looking for
