Corrosion Prevention and Friction Reduction Coating and Low Temperature Process
This invention relates to a structural coating comprising a polymeric resin, a borate-based additive, and a dynamic stabilization material. The borate-based additive provides corrosion protection through electrochemical binding of active surface corrosive sites, lubrication enhancement through the creation and re-supply to a surface where friction contact occasionally occurs of a weak slip lane crystalline material which may be a locally formed product utilizing local atmospheric humidity, and a material for reaction with an initiator to provide for freezing point depression during coating application. The dynamic stabilization material creates a balance of stabilized material for supply of corrosion protection product, lubrication reduction product, and freezing point depression product.

adding boric oxide to a polymeric resin to form a coating mixture;
applying said coating to said surface;
effecting passivation of said surface by continuous migration of boric acid to specific areas to be passivated, said migration being driven by an established chemical potential gradient; and
reducing the coefficient of friction through migration of boric acid to an operative surface in contact with an environment of nonzero humidity, said migration also being driven through a locally derived chemical potential gradient.
