"We're all doing the same

"We're all doing the same thing," someone told me the other day. If we really are then I propose as long as we're having as much fun as @rob.lea on a Wasatch powder day what difference does it make? #skiing #wasatch #mountains #snow #powder #itsallthesame

An extract on #powder

Powder (hundred), an ancient subdivision of Cornwall in the United kingdom Powder, Copper and Coal, the official mascots of the 2002 Winter Olympics in Salt Lake City Protocol for Web Description Resources (POWDER), a W3C Working Group Powder snow, freshly fallen, uncompacted snow

The initial working party was formed in February 2007 with the W3C Content Label Incubator Group's 2006 work as an input. On 1 September 2009 POWDER became a W3C recommendation and the Working Group is now closed. POWDER supersedes the previous W3C specification PICS.

Because powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces. Because no carrier fluid evaporates away, the coating process emits few volatile organic compounds (VOC). Finally, several powder colors can be applied before curing them all together, allowing color blending and bleed special effects in a single layer. While it is relatively easy to apply thick coatings which cure to smooth, texture-free coating, it is not as easy to apply smooth thin films. As the film thickness is reduced, the film becomes more and more orange peeled in texture due to the particle size and glass transition temperature (Tg) of the powder. Most powder coatings have a particle size in the range of 2 to 50 (Microns), a softening temperature Tg around 80 C, a melting temperature around 150 C, and are cured at around 200 C. for minimum 10 minutes to 15 minutes (exact temperatures and times may depend on the thickness of the item being coated). For such powder coatings, film build-ups of greater than 50 (Microns) may be required to obtain an acceptably smooth film. The surface texture which is considered desirable or acceptable depends on the end product. Many manufacturers actually prefer to have a certain degree of orange peel since it helps to hide metal defects that have occurred during manufacture, and the resulting coating is less prone to showing fingerprints. There are very specialized operations where powder coatings of less than 30 micrometres or with a Tg below 40 C are used in order to produce smooth thin films. One variation of the dry powder coating process, the Powder Slurry process, combines the advantages of powder coatings and liquid coatings by dispersing very fine powders of 15 micrometre particle size into water, which then allows very smooth, low film thickness coatings to be produced. For garage-scale jobs, small "rattle can" spray paint is less expensive and complex than powder coating. At the professional scale, the capital expense and time required for a powder coat gun, booth and oven are similar to a spray gun system. Powder coatings have a major advantage in that the overspray can be recycled. However, if multiple colors are being sprayed in a single spray booth, this may limit the ability to recycle the overspray.
