PCT No. PCT/GB94/00538 Sec. 371 Date Nov. 29, 1995 Sec. 102(e) Date Nov. 29, 1995 PCT Filed Mar. 17, 1994 PCT Pub. No. WO94/21458 PCT Pub. Date Sep. 29, 1994An apparatus for and a method of forming a metal coated with a polymer is achieved through the provision of a reservoir containing a cooling liquid having a relative undisturbed upper surface. A metal coated with a polymer is introduced into the cooling liquid through the upper surface and is subject to quenching liquid at a temperature Tq directed at the polymer coated metal substantially immediately below the cooling liquid upper surface and substantially along the entire predetermined width thereof. This achieves rapid and uniform cooling in the absence of bubble formation and/or quenching liquid surface agitation to assure desired crystalline formation of the polymer absent the polymer blemishes.
