    Abstract: Epoxy coating powders for application to substrates by fusion coating process. The resultant coating protects the substrates from corrosion when used in hostile environments. The epoxy coating powders comprise (a) unmodified epoxy resins having an average functionality greater than 3; (b) an aromatic polyfunctional amine curing agent; (c) at least 50 parts by weight of resin per hundred parts by weight of filler; and (d) a boron trichloride catalyst. The epoxy coating powders are particularly suitable for protecting oil field gear used down hole such as drill pipe, filter screens, production or gas recovery tubing and the like.

    Abstract: A plastic hose of limited conductivity designed to bleed static electric charges such as encountered in paint spraying. The hose has a conventional tube (2), reinforcement (3 and 4), and cover (5). The novel element is a static electric drain element (6) mounted between two components of the hose comprised of a tape or beading made from a beat sinterable thermoplastic material filled with carbon black.
