Electrostatic Flocking is the last word in how to get the best "Flock".
It is the action of an extremely high voltage applied between the applicator and the object being coated. If you are familiar with "Powder Coating", it is much the same principle.
The object to be flocked is thoroughly cleaned either by bead blasting or chemical means. It then goes to the spray booth where it is placed on a negatively charged pad and coated with the appropriate adhesive to facilitate a strong bond with the flock material.
We use either rayon or nylon fibers, depending on it's future use. The nylon is best for heavy outdoor use and is very slick and does not stain easily. The rayon is a softer fiber and grabs onto slick surfaces such as record albums.
Because of the high voltage (10 to 40,000 volts) that creates an Ion flow, or a positve/negative charge on the fiber as it leaves the applicator. One end of the fiber is charged to a positive and the other is negative. it is literally sucked to the object being coated. The fibers strike the adhesive with the positive charged end of the fiber, pulling that end through the adhesive until it reaches the metal object being coated. It then loses some of it's charge, but remains standing erect. As other fibers are applied, they too fill all of the gaps possible end first. Thus a much denser coating because none of the fibers are laying down and taking space the other fibers need.
The end result is that all fibers are standing perfectly vertical to the object. When baked at a low temp for 4 to 8 hours, They are permently bonded to the surface of the object. The excess fibers that did not have room to reach the adhesive can then be blown off and recycled on the next job using that color.
Many people have been taught the "Old Way" of flocking and that is simply springling the flock material over a painted surface. This works great for decorative purposes because the fibers are laying flat in the paint and when cured, leave a nice jewelery box look. This is useful for some types of applications, but commercial and heavy use applications will obtain more life from an electo-statically applied flock. The wearing surface of the flock is the very tips of the material and not the mass of tumbled flock which will soon wear through. And the visual of an electrostically flock object is that of an extremly tight felt cover that cannot be achieved by any other method.

Received it earlier this wk. BEAUTIFUL work. The electrostatic method does make a difference!
