Wow, a paint question! And with hocus-pocus space age technology thrown in!
This is turning out to be a pretty good day.
Ok, so these round, smooth, hollow ceramic spheres have a low surface to
volume ratio compared with ordinary paint fillers like talc, clay or crushed
limestone, so the expensive stuff - the acrylic resin - gets stretched
further. The addition of these lightweight spheres means the paint ends up
lower in density and it takes less resin to make a gallon of paint. This more
than pays for the cost of the microspheres, usually. That's OK, though, it
doesn't generally compromise paint performance.
The insulation thing is something else. If energy cannot radiate through a
vacuum, how come the sun heats the earth's surface? Besides that, heat can be
readily conducted along the walls of the spheres. Dumb marketing talk. There
oughta' be a law. Maybe if you apply the paint 12" thick you can build
some "R" value.
As for "elastomeric" being equal to something bad and unbreathable, I will
have to challenge the group's sensibiltites on that one. Show me the data! I
have seen elastomeric coatings (including a couple of ours) out-breathe some
of the so-called 99% breathable silicate coatings. Pore structure, pigment
volume concentrations, microfoam and film thickness are factors that affect
moisture vapor transmission rates. Some elastomerics are extremely breathable,
some aren't.
Acrylics, in general, are a pretty useful useful family of polymers and they
aren't necessarily elastomeric. Bullet-proof glass is actually an acrylic
plastic, a fairly hard one. Latex caulks are based on relatively soft ones.
They tend to be more weather and UV-resistant than oil-based paints and
varnishes, and with proper preparation can last a lot longer than they usually
do. A good acrylic paint, properly applied, should provide 20 or more years of
service.
