Yes it does. That is part of how it works. The coating is there to reduce the surface tension of the water so that vapor bubbles do not form on the surface so that the coolant always stays in contact with the surface. In Diesels running older coolants supplemental coolant additives are used to do this function. The coolant gets regularly tested for the concentration of the additives as to much can damage the engine due to excess deposits and reduced cooling efficiency. Yes, too much is no good. The slime layer is an insulator. Make it thick enough and you will think you are doing wonders with that lower temp guage reading when in fact the cylinder walls may actually be running hotter. Lower gauge readings are not always a sign of improvement.

Be careful with Water Wetter. It will leave a residue after a while.
Google "Water Wetter Brown" or "Water Wetter Slime"
Cheers,

that is adddressed clearly right on the side of a bottle of Water Wetter..
they site a dino test ,
using plain water,
plain water with water wetter,
50/50 a-frz mix,
and that mix with water wetter.
water with water wetter cools best..
they also mention that an anti-frz misture of less than 50/50 ( less a-frz ) cools better than 50/50.
it works too.
had this happen ..
85 Adventurewagon , 2.1 waterboxer engine stock 1.9 cooling system ..
but I added the 2.1 type oil cooler..
and water wetter..
went on a 1,500 or so mile trip ..
my temp needle was glued dead in the middle of the temp gauge scale ..
hills or speed didn't make the needle budge.
