I have had very good luck using a Birchwood Casey product called " pitchblack" it is a cold process black oxide solution much like a cold bluing, only stronger. The oxide can also be formed by an electrolytic process in anodizing. They told me if I want to do black oxide to use their equipment at work.
A review published in the Journal of Obesity in 2011 that looked at 12 clinical trials found that Garcinia Cambogia can increase weight loss by about 0. 88 kg, or 2 pounds, on average, over a period of several weeks (13). Their conclusion sums it up quite nicely: …Garcinia extractsHCA can cause short-term weight loss.
The main advantage of Fractal Black coating for us is the relatively high blackness at low temperatures (10KK) of the source of the thermal radiation achieved by small thickness of the coating (thin layer which is 40 times thinner than our epoxy layer). Steel Conversion Coatings (Black Oxide & Phosphate) Black Oxide: Black Oxide is a conversion coating formed by a chemical reaction with the iron in the metal to form an integral protective surface. (Contrasted to an applied coating which bonds to the metal but does not react chemically.). Acktar is a world leader in high absorptance & high emissivity black coatings for stray light suppression in high performance optics. The combination of a very low reflectance, high thermal stability, excellent adhesion, and low outgassing in a coating that is only a few microns thick is very unique.
