  • Publication number: 20110036262
    Abstract: This invention relates to a structural coating comprising a liquid carrier (e.g., paint), 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.
