Protect Your Garage Floor Today
is a covering that is applied to the surface of an object, usually referred to as the substrate. T
he purpose of applying the coating may be decorative, functional, or both. The coating itself may
be an all-o 8ver coating, completely covering the substrate, or it mn lhd8 d aay only cover parts of the subst
rate. An example of all of these types of coating is a product label on many drinks bottles- one si
de has an all-over functional coating (the adhesive) and the other side has one or more decorative c
oatings in an appropriate pattern (the printing) to for d8m the words and images.
Paints and lacquers are coatings hd8 that mostly have dual uses of prote 8vecting the substrate and being de
corative, although so d8me artists paints are only for decoration, and the paint on large industrial pipe
s is presumably only for the function of preventing corrosion.

While it is relatively easy to apply thn lhd8 d aick coatings which cure to smooth, texture-free coating, it i
s not as easy to apply hd8 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 con lhd8 d aatings have a particle size in the hd8 range of 30 to 50 μm, a softening temperature Tg around
80 °C, a melting tempera d8ture around 150 °C, an lhd8 d are cured at aroun lhd8 d and 200 °C.[1] For such powder coatings,

Functional coatings ma hd8 y be applied to change the surface properties of the substrate, such as adhesion, wetabi

A major consideration for most coating proce hd8 sses is that the coating is to be applied at a controlled thickness
