Cleaning:

• All parts to be coated are first cleaned using a high electrostatic sterile de-ionized water solution.  The parts are either dipped or sprayed into the cleaning solution.  Parts are dried via ambient temperature and sent to the waiting area for coating

Coating:

• Depending on the size, volume, configuration, substrate or mechanical characteristics, all parts to be coated are either sprayed or dipped
   

• All TUA formulas are applied via Ionic-Exchange.  TUA formulas contain hydro/halo carbons of which post application "flash", resulting in a covalent bond between the formulas and the substrate
   

• TUA coatings last the lifetime of the original device coated.  Thickness of TUA formulas is completely dependent on the formula applied and the original substrate of the device coated

Chemical bonding is an attractive force between atoms strong enough to permit the combined aggregate to function as a unit.  A more exact definition is not possible because attractive forces ranging upward from zero (0) to those involving more than 250 kcal per mole of bonds are known.  A practical lower limit may be taken as 203 kcal per mole bonds, the work necessary to break about 1.5 x 10 to the 24th power bonds by separating their component atoms to infinite distance.

All bonds appear to originate with the electrostatic charges on electrons and atomic nuclei.  Bonds result when the net coulombic interactions are sufficiently attractive.  Different principal types of bonds recognized include metallic, covalent, ionic and bridge.

Bridge bonding involves compounds of hydrogen in which the hydrogen bears either a positive or negative charge.  When hydrogen is attracted by a polar covalent bond to one molecule, it may attract another molecule, bringing the two molecules together.  If the hydrogen is positive, it may attract an electron pair of the other molecule and is called a protonic bridge.  If the hydrogen is negative, it may attract, through a vacant orbital, the nucleus of an atom of a second molecule and is called a hydridic bridge.  Such bridges are at the lower range of bond strength, but may be very significant in their effect on the physical properties of condensed states of those substances in which they are possible.

Ionic bonding is the electrostatic attraction among oppositely charged ions.

Metallic bonding is the attraction of all the atomic nuclei in a crystal for the outer shell electrons that are shared in a delocalized manner among all available orbitals.  Metal atoms characteristically provide more orbital vacancies than electrons for sharing with other atoms.

Covalent bonding results most commonly when electrons are shared by two atomic nuclei.  Here the bonding electrons are relatively localized in the region of the two nuclei, although frequently a degree of delocalization occurs when the shared electrons have a choice of orbitals.  The conventional single covalent bond involves the sharing of 2 electrons.  There may also be double bonds with 4 shared electrons, triple bonds with 6 shared electrons, and bonds of intermediate multiplicity.

Covalent bonds may range from nonpolar, involving electrons evenly shared by the two atoms, to polar, where the bonding electrons are very unevenly shared.  The limit of uneven sharing occurs when the bonding electron(s) spend(s) full time with one of the atoms.  This makes this atom into a negative ion and leaves the other atom in the form of a positive atom.
