Latest/greatest highest rated solar reflective paint or coatings?

Latest/greatest highest rated solar reflective paint or coatings?

Latest/greatest highest rated solar reflective paint or coatings?

(OP)
Of commercially available paints or coatings, what's among the highest rated for reflectance of visible light?

Thank you for any response.

Thanks for link, berkshire.

Best product I saw over there was 90% Light Reflectance Value (LRV), unless I missed something.

Essentially a gloss untinted white paint is going to be as good as you can get.
B.E.

You are judged not by what you know, but by what you can do.

That's my thinking, too.

Just trying to find what's best, to get every reflective % possible,
both for PAR light and to minimize heat absorption into the surfaces.

Higher titanium dioxide %'s in formulation seems to be key, but then
there's also some nano tweaks being utilized by some to boost it, too.

Looking into roof top coatings, too. Some claim above 90%, as long as
kept clean.

RE: Latest/greatest highest rated solar reflective paint or coatings?

Sure, there's silver, but that's none trivial for maintenance, although there are supposedly manufacturers that claim moisture resistance. Generally, engineering solutions try not to depend on a single component.

TTFN (ta ta for now)

(OP)
IRstuff,

Are there any commercially available, reasonably priced, silver nano particle paints or coatings available?

- Shane

RE: Latest/greatest highest rated solar reflective paint or coatings?

(OP)
Trying to determine and acquire the best available is not.

RE: Latest/greatest highest rated solar reflective paint or coatings?

(OP)
If interested, best commercially available product I've found so far...

http://www.nationalcoatings.com/acryshield-ultra-h...

Bright White

Solar Reflectance (ASTM C1549)

Initial .92
Aged .87

NASA has used some on exterior of Ares I-X Rocket, high reflectivity being primary reason.

If you know of anything better, that's readily available and reasonable, please let me know, thanks.

- Shane

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
